From a wheelbarrow to a wheelchair

SANRAL’s Wellness Programme makes a dream come true for 78-year-old Eastern Cape grandmother. 

SANRAL launched its Wellness Programme in 2011 and rolled the programme out to different parts of the country. In 2016, the programme was introduced into the Eastern Cape. 

Receiving a wheelchair was a life-changing experience for Ntakimba Mamkone, an elderly woman who, for years, had endured being pushed in a wheelbarrow for over 12-kilometres to and from a local clinic in Cwele, a village nearby Mthatha in the Eastern Cape Province.

Her dream of owning a wheelchair turned into reality after her plight was identified through a SANRAL wellness programme.  

Nombuso Feke, a wellness programme participant and female-owned Small Medium and Micro Enterprise (SMME) working on the South African National Roads Agency (SOC) Limited’s (SANRAL’s) R61 Routine Maintenance project, took it upon herself to assist and donated the wheelchair.

“In 2014, my mother had her leg amputated due to diabetes. This awakened me to the hardships people in her community face and I always wished I could do more to assist, especially when it came to Mamkone,” said Feke. 

Bringing healthcare closer to workers

SANRAL launched its Wellness Programme in 2011 and rolled the programme out to different parts of the country. In 2016, the programme was introduced into the Eastern Cape.

The purpose of the programme is to bring healthcare closer to workers and their families, to promote a healthy lifestyle and improve the wellbeing SANRAL’s Routine Road Maintenance (RRM) project teams.

Xoliswa Chubana, SANRAL Southern Region’s Community Development Specialist, said: “The programme does not only concentrate on HIV/AIDS awareness, but also on the holistic wellbeing of all employees working on RRM contracts. The Wellness Champion creates awareness around certain symptoms and prevention of communicable and non-communicable diseases. HIV Counselling & Testing (HCT) and health screenings are conducted bi-annually on site.” 

There are 18 Wellness Champions throughout all SANRAL’s RRM sites in the Southern Region.

“The Wellness Champions on all projects are encouraged to carry out outreach programmes on their sites. The R61 Mthatha to Port St Johns was one of them driven by Buli Dlutu,” Chubana said. 

Ma Mamkone is 78-years-old, lives with a physical disability and has 12 grandchildren. One of her granddaughters dropped out of school to take care of her. She would transport Ma Mamkone on a wheelbarrow to and from the clinic for her appointments.

Feke said; “After SANRAL appointed me as an SMME on the R61 Section 8, not only was I able to support my own family but Ma Mamkone, whose situation I was able to relate closely to because of the personal struggle and suffering of my mother’s experience”.  

Feke is glad to have helped her community and is looking forward to helping more families.

Chubana said: “SANRAL and SMMEs are working together to ensure better lives for each one in South Africa through the continuation of promoting and creating awareness about healthcare to the workers and their families. Family members also participate in the programme.  

“The Wellness programme also provides family visits by the Wellness Champions and talks are given about the current wellness topic of the month. During HIV counselling and testing the workers are allowed the opportunity to bring up to five of their families.”

Minister officially opens iconic Mt Edgecombe Interchange

This upgrade has forever changed the landscape, and will no doubt become a recognizable landmark.

Five years after the first pile was driven into the ground for major upgrading, the iconic Mount Edgecombe Interchange was officially opened by Minister of Transport Blade Nzimande, a fitting end to the 2018 October Transport Month. 

He described the interchange as “a veritable civil engineering work of art” and said it was a fine example of infrastructure development that has multifarious spin-offs: it contributes greatly to easing traffic congestion, promotes road safety and is also a significant business enabler. 

“Today’s ceremony comes between the stimulating announcement last Friday of the promised inflow of investments totalling R290-billion that will jump-start the economy, and the drawing to a close of October Transport Month 2018, which has showcased the country’s transport infrastructure development and services,” he said. 

The South African National Roads Agency (SOC) Limited (SANRAL) awarded the contract for upgrading of the intersection of the N2 and M41 to ease chronic congestion. 

SANRAL CEO Skhumbuzo Macozoma said the R1,1-billion interchange, which is one of the largest projects undertaken by SANRAL in KwaZulu-Natal, is more than a masterpiece of award-winning architecture – it is a vital artery of the greater eThekwini metropolitan highway system and has greatly contributed to SMME development. 

He said: “Due to the expansion of the uMhlanga and La Lucia Ridge areas, the existing interchange had been operating at capacity with vehicles backing up on the M41 and onto the N2 in peak hours. 

“An additional 40 000 vehicles were entering or leaving the N2 from the M41 daily resulting in substantial queuing of vehicles during the day.  

“This, together with expected future expansions and development of the Cornubia area, required the existing interchange to be upgraded in order to improve the flow to and from the N2 and M41 to the supporting road network.” 

A changed landscape 

This upgrade has forever changed the landscape, and will no doubt become a recognisable landmark. 

The new four-level interchange facility provides at least two lanes on each of the major movements. The upgrade includes the implementation of directional ramps, eliminating the need for controlled signalisation, thus ensuring free flow of traffic in all directions. 

The construction was jointly funded by SANRAL and KwaZulu-Natal Department of Transport and was undertaken by the South African branch of Italian construction company CMC di Ravenna. 

Two incrementally launched bridges are part of the interchange upgrade. One bridge, which is 948m long – the longest incrementally launched bridge in South Africa – joins the Mt Edgecombe side of the M41 with the N2 South. The other bridge is 440m long and joins the uMhlanga side of the M41 with the N2 North. 

The 948m bridge has 23 piers and two abutments and was built from two ends – one portion launched on a curve and the other on a straight. 

To provide for the safety of pedestrians, a pedestrian bridge has been constructed over the N2 and will connect to new footways. 

In addition, lighting has been installed to ensure the whole interchange is lit at night for increased safety. 

Engineering achievements 

The multiple engineering achievements behind this mammoth project are testimony to the exceptional skill and abilities of the entire construction team.  

The project engaged 80 designers at the peak of the design phase. Not a single road was closed permanently during construction. 

The improvement of roads has knock-on effects – it helps to develop SMMEs and create jobs. 

The maximum number of persons employed at a time by the Mt Edgecombe Interchange contractor and sub-contractors was 803 of which 724 were from the eThekwini target area, with a total of R240-million spent on wages to date. 

A total of 31 sub-contractors have been employed with work to the value of R59-million performed by 21 SMMEs to date. 

Resident engineer Henk Kaal said although there was a lot of skepticism about the completion date of the project, motorists are now beginning to smile as they start enjoying the improved flow of traffic.

Roads bring opportunity and upliftment to Mzamba

The project is part of the community development and small, medium and micro-sized enterprises (SMME) training programme.

Mayor Mafumbatha was joined by Welekazi Ndika, SANRAL Southern Region Stakeholder Relations Coordinator (left), Ntsizakalo Ngalo a Senior Facilitator for MAJV, and Hilda Cwele a Community Development Worker on the project.

Ten SMMEs received their SAQA accredited NQF certificates at the announcement of the completion of the construction of a 4.5km community access road in Mzamba in the Mbizana Local Municipality. 

The road construction project, which started in June 2016 and took two years to complete, is part of the community development and small, medium and micro-sized enterprises (SMME) training programme, which forms part of small business support strategies to optimise local economic development through the N2 Wild Coast Toll Road (N2WCTR) development in the Eastern Cape. 

Welekazi Ndika, SANRAL Southern Region’s Stakeholder Relations Coordinator, said: “The area has benefitted from the contract as the improvement of skills and knowledge has been critical to the built-environment capacity development within the municipality to assist the municipality to be able to support the provision of Sustainable Rural Local Economic Development.” 

In addition to the completion of the access roads, the community hall was also refurbished. 

Locals voice appreciation 

Chief Lunga Baleni said he was happy the project had been completed.  

“I hope this relationship with SANRAL will continue. I would like to encourage SANRAL to continue with their community development programmes in our area,” he said. 

Mbizana Local Municipal Mayor Councillor Daniswa Mafumbatha said they were happy to see the “great work” that was done by the SMMEs. 

“The roads built are beautiful. We can see that the money was spent well. We can see the growth in our SMMEs. I would like to take this opportunity to appreciate the job opportunities that were created on this project. We like what we see. The certificates handed out are not given to people because of their associations, but for their hard work and training,” said Mayor Mafumbatha. 

Mafumbatha added that it was “through the collaboration between the Municipality and SANRAL that the hall was also refurbished”. 

Dr Mongezi Noah, SANRAL Southern Region Community Development Specialist, said there more projects were on the cards and that the completion of the community access roads was just the beginning. 

“I encourage SMMEs to tender to work on other projects. The municipality can utilise the SMMEs from the area that have been developed,” Noah said. 

Ward 24 Councillor Ntlahla Hlebo said the community was “very happy” the road had been completed and the hall refurbished. 

Hlebo said: “Before this new road our road was gravel. During floods in the past, there would be big potholes. During heavy rains it was difficult for an ambulance to drive to a house, instead, people had to arrange for a lift or push someone in a wheelbarrow to the R61 and meet the ambulance there.  

“The training the SMMEs received has made them employable. They can look for work anywhere.” 

SMMEs benefit 

Nombali Hlongwe, a co-owner of Pumlani Construction, was elated with her certificate. 

“Now that the project is complete, I am looking at upgrading to CIDB level and am now looking at tender opportunities. Now that I have completed the project and received the certificate, I feel that the world has opened a lot of opportunities for me. The project has been successful for all of us,” said Hlongwe. 

Sethu Sibeni from Ngxathi Trading was very happy to have received his NQF level 3 certificate. Sibeni worked as a supervisor on the project. 

“The community appreciates the new road.  During heavy rains it was not easy to travel on this road. Having a tarred road means that public transport can now access the communities easier. The completion of the access road also means there is quicker access to the R61,” said Sibeni. 

Sibeni’s goal is to own a block yard and supply local businesses with material. 

The two-year project created opportunities for 50% women-owned Small Medium and Micro Enterprises (SMMEs), 70% youth-owned SMMEs and jobs for 130 people from the local community. 

Fifty of the local community members were also trained and received SAQA accredited NQF Level 2 certificates in road construction, while the remaining 80 received certificates for technical skills gained on the job.  

Sixty-four local SMMEs who did not qualify to be part of the construction project, received tendering training for construction contracts. 

Upgrading contractors 

Following the completion of the project, it is anticipated that Construction Industry Development Board (CIDB) upgrades will take place, with ten Grade 1CEs upgrading to Grade 2CE contractors. 

The training project entailed five phases, including: 

  • assessment of site conditions, socio-economic conditions of the area, and the availability of resources; 
  • design of approximately 4500m of community access road; 
  • local SMME participation through open tender process – 10 subcontracted on the construction of the haul roads; 
  • theoretical and practical training of the local SMMEs;  
  • construction of community access roads using labour-enhanced construction methods; 
  • CIDB Grading 4 local sub-contractor was used to construct earthworks and layerworks, while other suppliers were used to supply kerbs, water, sand and various materials to the project; 
  • Community policing forum was used for security on site; 
  • Various service providers used for catering and supply of toilets. 

“The community has benefitted from the contract as the improvement of skills and knowledge is critical to the building of capacity within the community. This will assist the Municipality in supporting the provision of Sustainable Rural, Local and Economic Development,” said Gcobani Socenywa, project manager for SANRAL Southern Region.

SANRAL develops knowledge economy with all-weekend Hackathon for youth

The Hackathon challenged participants to use the data and technology available to them to come up with tangible solutions for the road user.

The South African National Roads Agency (SOC) Limited (SANRAL) understands the importance of and is fully committed to developing South Africa’s knowledge economy, using the pillars of knowledge sharing, skills transfer, collaboration and innovation.  

SANRAL and Electronic Toll Collection (ETC) recently partnered with WhereIsMyTransport to host the ETC Hackathon in Cape Town. 

With the theme of Collaborate & Innovateparticipants in the Hackathon were invited to create innovative smart mobility applications utilising both Gauteng Freeway Improvement Project (GFIP) toll gantry data and WhereIsMyTransport public transport related data. 

SANRAL has been innovative  

SANRAL, manages the tenth-largest national road network in the world and has, for some time, been operating in the digital space with its Freeway Management System that deploys dedicated cameras on 520km of the busiest freeways across the country.  

Here, real-time traffic data is collected and used to determine how best to respond to an incident, dispatching the relevant response entity and ultimately saving lives on our roads. 

Randall Cable, SANRAL’s Western Region Manager, officially opened the Hackathon challenging the participants to use the data and technology available to them to come up with tangible solutions for the road user. 

“It is encouraging to see the low average age of the participants (under 25 years) and how committed these young South Africans are to be part of the change they want to see in our country,” said Cable. 

The Hackathon was sponsored by ETC, which was established in 2009 to supply and manage an integrated tolling system on behalf of SANRAL. 

According to Darewees Taliep from ETC, the system handles 550 000 transactions per hour, which equates to 155 transactions every second. ETC made a random selection of transactional data available to the participants for them to create a mobile solution to aid safe and improved road user experiences.  

Some of the proposed avenues included drawing usage/behaviour patterns, analysing traffic volumes, customer service centres and identifying foreign vehicles. 

“It is believed that 90% of the world’s big data was gathered in the last two years only. Big data analytics and building solutions using this data is definitely where the world is headed,” said Talliep in his briefing session to the participants. 

Innovation in mobility 

In Cape Town, 50% of all public transport trips occur in minibus taxis and involve primarily women and children under the age of 13.  

They do so without a schedule or the ability to plan according to a timetable, yet they must get to work and to school on time. This is according to WhereIsMyTransport, who facilitated and provided expert tech and data support during the weekend. 

The role of innovation in mobility for our emerging cities was the background against which they encouraged the participants to think out the box when developing public transport solutions that would make life easier for the ordinary man on the street, to navigate from point to point. 

Through their public transport API, they gave participants access to all the main public transport platforms, ie. bus, taxi, train, walking routes, etc, and these could be integrated to best achieve usable public transport solutions for the public. 

The winning team, which conceptualised a mobile solution that delivers turn-by-turn public transport directions via SMS or WhatsApp, walked off with a R20 000 cash prize and a year’s worth of free access to the WhereIsMyTransport Public Transport API. 

Cable said: “SANRAL firmly believes in the ability of the youth to add value to the broader transport industry. We have invested in a Technical Innovation Hub, which is thriving with young engineers exploring the extent to which technology can improve road user experiences, particularly as we head in the direction of smart cities, which demands smart mobility and disruptive thinking.  

“We are incredibly excited about the different solutions the Hackathon participants came up with to challenge the status quo, and we look forward to seeing some of these ideas come to fruition.”

Less traffic congestion for Hartbeespoort Dam

Motorists will enjoy a free flow of traffic and there will be a better link to the North West Province from the west of Pretoria and Johannesburg once the project is completed. 

Challenges faced during construction mainly relate to the quality of the in-situ material from the cutting slopes in the Magalies Neck, and the supply of suitable fill material locally.

Traffic flow in the Hartbeespoort Dam is set to improve with construction work on the R512-PWV3 making good progress.  

The estimated completion date is December 2019.   

Once the project is completed, motorists will enjoy a free flow of traffic and there will be a better link to the North West Province from the west of Pretoria and Johannesburg.  

Alex van Niekerk, Planning, Toll and Transport Manager of the South African National Road Agency (SOC) Limited (SANRAL), said: “The completion of the project will also ensure that long distance movements do not interfere with local traffic. The road stretches from the R512 to the west of the dam, through Pampoennek to the connection with the N4 to Rustenburg.” 

Details of the project 

Challenges faced during construction mainly relate to the quality of the in-situ material from the cutting slopes in the Magalies Neck, and the supply of suitable fill material locally. The project was originally scheduled to be completed in October 2019, but this has been extended due to changes made to the Game Underpass, which resulted in a larger structure being erected and thus requiring more time to complete.                                                                                               

The excavations at Pampoennek are progressing well and are approximately 80% completed.   

The contract must comply with the environmental authorisation and management plan issued by the Department of Environmental Affairs.  

As part of the plan, indigenous flora was rescued from the affected areas and will be reinstated into its natural environment on the cutting slopes in the Magalies Neck. 

As part of SANRAL’s project objectives to actively promote the development of small, medium and micro enterprises (SMME) and job creation, the contractor has created 165 jobs and utilised 21 SMMEs to date.  

SANRAL will continue to work on reducing traffic congestion in the area said Van Niekerk.  

“We look forward to successfully completing this project without harming the environment,” he said.

“Pay your tolls!” is the call from the new Minister of Finance

Tito Mboweni singled out the road network as a vital element that “supports growth and development” in an economy that is dependent on land transport. 

Minister of Finance, Tito Mboweni, singled out the road network as a vital element that “supports growth and development” in an economy that is dependent on land transport. 

A strong commitment to prioritise the country’s road network and a passionate plea to South Africans to “pay our tolls” were important features of new Finance Minister Tito Mboweni’s first Medium-Term Budget Policy Statement. 

This is vital to restore a culture of payment in the country, instil confidence in investors and ensure sustainable service delivery. 

The Minister also highlighted SANRAL’s partnerships with concessionaires as examples of how the public and private sectors can work together to deliver vital infrastructure.  

“These kinds of partnerships will be accelerated,” he announced. 

Speaking in Parliament, Mboweni devoted considerable time to announce steps taken to revitalise the country’s infrastructure as a core element of broader plans to attract investment, stimulate economic activities and create jobs. 

He singled out the road network as a vital element that “supports growth and development” in an economy that is dependent on land transport. 

“Over the medium term, funds are reprioritised to enable the strengthening and rehabilitation of the national non-toll road network – of which about 75% is beyond its design life,” he said. 

User pay principle 

Mboweni also committed to the user-pay principle as “the most efficient and effective way to ensure that the direct benefits of services are paid for by those who use them”. 

“If we want road transport that works, we need to pay our tolls,” he said. 

“We need to restore a culture of payment in this country to ensure the sustainability of our services and to give confidence to those institutions who invest in our bonds.” 

In the Medium-Term Budget Policy Statement – released together with the Minister’s speech – Treasury committed itself to the allocation of R5.8-billion to SANRAL for 2018/19.  

This amount is shifted to SANRAL within the adjusted budget for the Department of Transport (Vote 35). 

It notes that SANRAL has government guarantees of R38.9-billion, but there is a risk that the guarantees might be called in because it is not generating enough cash from the Gauteng Freeway Improvement Project to settle redemptions falling due over the medium-term period. 

Mboweni’s speech built strongly on the recent announcements by President Cyril Ramaphosa to prioritise infrastructure and revitalise state-owned companies.  

It was delivered on the eve of the National Investment Summit in Sandton where the President announced details on government’s progress to attract both local and foreign investment in the economy. 

The current reconfiguration of state-owned companies requires the country “to take a hard look at how they operate”.  

It also presents “an opportunity to demolish the walls that exist between the private and public sectors,” Mboweni said. 

Successful partnerships with the private sector – such as on the N3 highway and the N1/N4 Platinum Road – are examples of how service level agreements can be put in place to define relationships between the two sectors. 

Eight highlights from the 2018/19 Medium-Term Budget: 

  1. SA’s growth forecast has been revised down from 1.5% to 0.7%, but is expected to pick up to over 2% by 2021 “as confidence returns and investment gathers pace”. 
  2. The National Development Plan will occupy a central place in government policies and planning. This includes a commitment to strong, inclusive and sustained growth to sharply reduce unemployment, poverty and inequality. 
  3. Almost R16-billion of the 2018/19 Budget has been reprioritised towards infrastructure programmes and initiatives to support industrialisation. Investments in roads and transport infrastructure will improve access to social and economic facilities and help to attract investment, particularly in township economies. 
  4. Development finance institutions, multilateral development banks and private banks will be roped in to design, finance and implement infrastructure projects. Government will develop a framework and implement regulatory reforms to enable long-term investors to commit funds that will lead to returns on investment. 
  5. National Treasury will work with other department to deal with financial misconduct in all spheres of government. This will include the “employment of qualified, competent and incorruptible officials”. 
  6. No additional funds will be allocated for the implementation of the public service wage agreement. National and provincial departments will have to absorb these costs within their compensation baselines. 
  7. Treasury will work with the Auditor General to reduce fruitless, wasteful and irregular expenditure across the public sector and law enforcement agencies “will act against those implicated in wrongdoing”. 
  8. Government is working with the Johannesburg Stock Exchange to strengthen debt listing requirements for state-owned companies. This will lead to increased transparency and improved governance in this sector.

Tshwane Mayor urged to check his facts

SANRAL CEO Skhumbuzo Macozoma has echoed Finance Minister’s passionate plea to South Africans to pay road tolls.

 

SANRAL has achieved its 15th consecutive unqualified audit, as was revealed in its annual financial statements. The report includes a concern with respect to the future funding of roads. 

Following on Finance Minister Tito Mboweni’s backing for the user pay principle, Skhumbuzo Macozoma, CEO of the South African National Roads Agency (SOC) Limited (SANRAL) has sought to correct the “e-toll facts” given by Tshwane mayor Solly Msimanga. 

A strong commitment to prioritise the country’s road network and a passionate plea to South Africans to pay tolls were important features of new Finance Minister’s first Medium-Term Budget Policy Statement.  

This is necessary to restore a culture of payment in the country, instil confidence in investors and ensure sustainable service delivery. 

He singled out the road network as a vital element that “supports growth and development” in an economy dependent on land transport.  

The Minister committed to the user pay principle as “the most efficient and effective way to ensure that the direct benefits of services are paid for by those who use them”. 

Macozoma said: “Paying tolls is the law until decided otherwise. We urge motorists not to listen to calls for an e-toll boycott – this is how debt grows until when it is time to pay, motorists will find themselves short on funds.” 

Macozoma pointed out that the Tshwane Mayor’s “e-toll facts” were misrepresentations of the truth. 

Facts vs Fiction 

Msimanga: “R5.70 per litre of fuel and licence fees are not spent on road maintenance.” 

Fact: The fuel levy and vehicle licence renewal fees accrue to the national fiscus and are not ring-fenced for allocation to SANRAL. SANRAL’s allocation from Treasury is not linked to the fuel levy or vehicle licence fees. 

Msimanga: “93% of all e-tolls fees are leaving SA – only 7% is being used for maintenance of the road.” 

Fact: The e-toll operator is only paid for services delivered on the electronic toll collection system, as per tendered rates. Maintenance is not linked to the operator’s fee. 

Msimanga: “SANRAL has irregular, fruitless and wasteful expenditure of over R10bn.” 

Fact: Regulations define “irregular expenditure” as “expenditure incurred where there was non-compliance with any law or regulation”.
In the case of SANRAL, in 63% of cases the term “irregular” is used because of a disagreement with the Auditor-General (AG) over the interpretation of “the lowest acceptable price”.  

Neither the Public Finance Management Act (PFMA) nor the regulations provide a definition of what exactly “acceptable” means.  

SANRAL applied a statistical model designed by the University of Pretoria to determine this value for every tender.  

This was done to ensure sustainable pricing for SMMEs, who may otherwise be vulnerable to undercutting. This method was used for more than 11 years, during which there were no findings from the AG, nor complaints from contractors.  

In 2013 the AG declared the model non-compliant with the Preferential Procurement Policy Framework Act (PPPFA). Once the AG declared this methodology “irregular expenditure”, it was immediately abandoned and the absolute lowest price was accepted. 

Contracts already awarded based on this model could conclude because in all cases they represented good value for money. The contracts concluded in the 2017/18 financial year, but remain in the cumulative balance. 

Msimanga: “The system is corrupt and SANRAL must be investigated.” 

Fact: This claim is patently false. It has been publicly disproved many times. The former Public Protector, Thuli Madonsela, investigated SANRAL and there were no adverse findings. There were successive court actions. In no instance were there any negative findings on issues relating to governance at SANRAL and the e-toll project. 

Healthy finances 

SANRAL has achieved its 15th consecutive unqualified audit, as was revealed in its annual financial statements. The report includes a concern with respect to the future funding of roads. 

In the Medium-Term Budget Policy Statement (MTBPS) – released with the Minister’s speech – Treasury allocated R5.8-billion to SANRAL for 2018/19. This amount is shifted to SANRAL within the adjusted budget for the Department of Transport (Vote 35). 

“To call this a bail-out is mischievous; 87% of SANRAL’s finances are healthy, with the 13% toll portfolio under strain,” Macozoma said.

Warm asphalt is becoming the industry standard

When compared to hot mix asphalt, warm mix asphalt cools has less impact on the environment and is safer for workers. 

Warm mix asphalt is produced using temperatures up to 50 degrees Celsius lower than what is used for traditional hot mix asphalt. Less energy is needed to heat the warm mix asphalt, so it uses less fuel, decreasing the plant’s carbon footprint.

The benefits of using warm asphalt as opposed to hot asphalt on South Africa’s national highways have been lauded at an international roads conference in Durban. 

Krishna Naidoo, a Material and Pavement Specialist at the South African National Roads Agency (SOC) Limited (SANRAL) Eastern Region, said the roads agency was working towards ensuring that its stand-alone asphalt supply plants produced only warm mix asphalt (WMA). 

“In this way SANRAL will be leading the charge in worker safety as well as reducing its carbon foot-print in providing sustainable infrastructure. We are indeed more than roads,” Naidoo said. 

He was addressing delegates attending the conference themed, “Roads to Social and Economic Growth”, arranged by the South African Road Federation (SARF) in association with the Washington-based International Road Federation (IRF) and the Paris-based World Roads Association (PIARC). 

Less environmental impact 

Warm mix asphalt is produced using temperatures up to 50 degrees Celsius lower than used for traditional hot mix asphalt. Less energy is needed to heat the warm mix asphalt; thus, it uses less fuel, decreasing the carbon footprint. 

It is a greener process that has less impact on the environment, with reduced hydrocarbon emissions and greenhouse gases. Due to its lower temperature, it is also safer for construction workers to use. 

WMA’s journey in South Africa started about a decade ago with the formation of the country’s Warm Mix Asphalt Interest Group, led by Naidoo being elected the national coordinator. 

The WMA Interest Group led three major national trials that culminated in the publication of the South African Bitumen Association (Sabita) Best Practice guidelines and specifications for warm asphalt. 

“Through the process of these trials, the asphalt industry renewed its commitment to excellence, quality and efficiency. 

“But more importantly, it was the most tangible step by the entire asphalt industry, including clients, contractors and manufacturers, towards improving worker safety as well as reducing environmental impact,” said Naidoo. 

Hot versus warm mix 

Naidoo said: “When compared to hot mix asphalt, warm mix asphalt cools at a lower rate, so the paving season is extended, allowing road repairs and construction to finish more quickly. 

“This benefit helps save time and money on labour and equipment, as workers and tools are needed for a smaller span of time and projects can be finished more quickly. It also lessens the impact on traffic as projects finish faster and there are less interruptions to roadways.”   

The benefits of WMA, Naidoo said, were now being realised by more client’s country-wide and have also been included in the draft revision of COTO – Standard Specifications for Road and Bridge Works. 

“To date South Africa has successfully produced and paved over a million tons of WMA. 

“The latest success story has been the 370km haul of asphalt to a SANRAL job in Harrismith,” said Naidoo. 

He added that with the impending implementation of the Carbon Tax Bill, WMA will help contribute to offset the tax.

Rumble strips keep drivers on the right track and save lives

The strips, which replace traditionally smooth painted road markings, cause a tactile vibration and audible rumbling. 

International studies have shown that run-off-road (ROR) crashes can account for a large majority of the fatal single-vehicle crashes. 

There is nothing like a sudden rumble to alert inattentive drivers of potential danger when they drift from their lane. 

Hence the South African National Roads Agency (SOC) Limited (SANRAL) has authorised rumble strips – also known as sleeper lines, alert strips and wake-up calls – to be painted on the shoulder lines and between undivided dual carriageways of the N2 and N3 around Durban. 

Vibration and audible rumblings 

The rumble strips, which replace traditionally smooth painted road markings, cause a tactile vibration and audible rumbling to be transmitted through the wheels into the vehicle interior. 

The rumble strips are little balls of plastic paint dropped onto the road surface, which create a whining or humming noise when traversed by a vehicle tyre. 

International studies have shown that run-off-road (ROR) crashes can account for a large majority of the fatal single-vehicle crashes. 

ROR crashes are due to inattention, speeding, traction loss, over-reaction, crash avoidance and mechanical failure. Rumble strips only prevent ROR crashes due to inattention. 

New Zealand began using rumble strips since the late 1980s and has reported a reduction in ROR crashes by up to 80%. 

Hugh Brooks, SANRAL Eastern Region project manager, said rumble strips were used where there were very high volumes of traffic and where driver concentration was crucial. 

“Centreline rumble strips are used on undivided highways to reduce cross-over incidents and the resultant head-on collisions. 

“Shoulder rumble strips are used primarily to reduce run-off-road collisions. They alert distracted or drowsy drivers that they are leaving the roadway or crossing the centreline of the road,” he said. 

Joos Joubert of Lanino Traffic Markings, which has applied the rumble strips, said the innovative warning system was developed in Norway. 

Rumble drop markings 

He said the textured marking called Rumble Drop Markings (RDM) cause a noise when you drive over it and can be seen in the rain at night. 

Joubert said: “RDM consist of 25 to 50mm thermo-plastic drops that are 3mm high. Normal road markings provide only day-time visibility. If there are no street lights, the road markings are almost invisible. 

“On national and provincial roads, glass beads are applied on top of the wet paint and provide night time visibility. This effect is accomplished by the refractive index of the beads sending light rays back to the light source. 

“These road markings provide very good visibility during day time and night time, but as soon as any rain falls on the road markings the water covers the beads and the markings will not be visible at night.” 

With RDM the water drains instantly off the road markings and protruding beads, providing visibility at night and in wet conditions. 

He said there had been no complaints about the rumble strips – only compliments.

SANRAL-Wirtgen MoU levels the playing field for smaller contractors

Memorandum of Understanding will afford small to medium construction contractors’ full access to the Wirtgen Group’s full suite of leading equipment brands, as well as financing, training and logistics.

The South African National Roads Agency (SOC) Limited (SANRAL) and Wirtgen Group South Africa have signed a Memorandum of Understanding that will give small enterprises better access to the road construction machinery they need to execute major SANRAL-owned projects. 

The agreement will afford small to medium construction contractors’ full access to the Wirtgen Group’s full suite of leading equipment brands, as well as financing, training and logistics.    

“This is an important step in the broader national aim to transform the construction and engineering sectors and enable emerging black contractors, including enterprises owned by women and the youth, to participate more fully in major projects,” said Louw Kannemeyer, Engineering Executive at SANRAL. 

“Infrastructure development will be a major contributor to the efforts to attract investment to the country and was singled out at the recent Job Summit for its ability to create employment and stimulate economic activity. 

“We are delighted that a global leader in construction such as Wirtgen is stepping up to fill major gaps in the industry that constrain the growth of smaller contractors and impose barriers on their ability to tender for major work packages,” said Kannemeyer. 

Waylon Kukard, National Sales Manager at Wirtgen South Africa, said: “Equipment is one of the major success factors for contractors in the execution of their projects. If contractors are not well equipped, the country also faces the danger of sub-standard road infrastructure.  

“The agreement will afford upcoming contractors’ greater access to all Wirtgen Group equipment brands, namely Wirtgen, Vögele, Hamm, Kleemann, Benninghoven and Ciber.” 

Changing the landscape 

The agreement with Wirtgen is part of a process introduced by SANRAL to open the engineering and construction industries through its tender and enterprise development initiatives. It will greatly benefit smaller contractors who will now have access to the company’s range of equipment. 

Through its leading brands, Wirtgen offers a wide range of equipment, all the way from rollers, bitumen spreaders, sweepers, milling machines, recyclers, slipform pavers, modular asphalt pavers, to mobile asphalt plants and crushers and screens. 

Emerging contractors will be able to purchase or lease the sophisticated machinery required to meet the high standards that are in place within the South African road construction environment. 

This move will open new doors for Wirtgen to collaborate with small contractors by offering them access to finance, technical assistance, mentoring and logistical support. SANRAL and Wirtgen will also collaborate on issues such as training, supply chains and access to information about tendering processes. 

“We are confident that this MoU will increase the number of participants across the value chain of the road construction sector and contribute to fair competition,” said Kannemeyer.
