Plastic Road to Be Trialed In South Africa

• This week Kouga Municipality in the Eastern Cape announced that it will be building the first plastic road in South Africa.
• The local authority would be taking hands with a Scottish company and South African civil engineering experts to build the road.
• A 1km-stretch of Woltemade and Koraal Streets in Jeffreys Bay has been earmarked for the trial.
• The trial will be done at no cost to the municipality, with the respective partners set to foot the bill.

Horatio Hendricks, Executive Mayor of Kouga Municipality, made the announcement in Jeffreys Bay on Monday (11 March 2019). The local authority would be taking hands with a Scottish company and South African civil engineering experts to build the road.

“The backlog in road repairs for our region is estimated to be more than R500-million. While Kouga is strong financially, we simply do not have the rates base to deal with this backlog decisively,” he said. The DA-led Kouga Council has, therefore, been looking for innovative ways to slay this giant since taking power in the municipality in 2016.”

The search led Hendricks to Vicky Knoetze, a member of the Eastern Cape Legislature who first introduced the idea of solving some of South Africa’s problems through plastic roads to the Provincial Legislature in 2017. Her notion was, however, rejected at the time.

She facilitated a meeting between the municipality and Scottish innovators MacRebur, whose plastic roads have already been put to the test in the United Kingdom and other countries across the globe. Also present were Port Elizabeth-based civil engineering and construction companies SP Excel and Scribante Construction.

“I am delighted with the outcome and that Kouga has agreed to become the first municipality in South Africa and the continent to put the technology to the test, ” Knoetze said.

“Essentially we will be doing what we have done for years and will be doing till the end of days, which is building roads, just in a much more efficient and effective way.”

She said what MacRebur offered, was an enhancement of the asphalt mix traditionally used for the top layer of roads. “Non-recyclable plastic waste, which ends up in the ocean or clogging up landfill sites, is processed into pellets and used to replace a large component of the bitumen in a conventional asphalt mix. It is estimated that up to 1,8 million plastic bags can be used in just one kilometre of road”.

“The result is a road that is stronger and more durable. Water, the main cause of potholes, does not penetrate it as easily as with traditional asphalt mixes and it is also more heat resistant,” she explained.

Hendricks said Kouga was looking forward to the potential benefits of the trial.” Poor roads have a devastating impact on communities. It’s not only a danger to motorists, it is also bad for the economy as it scares off potential investors and makes it difficult for existing businesses to ply their trade.”

He said should the trial be successful, the municipality would like to see a factory being established in Kouga to produce the pellets locally. “In this way it will be a triple win for our people – better roads, less pollution and more job opportunities.”

He said a 1km-stretch of Woltemade and Koraal Streets in Jeffreys Bay has been earmarked for the trial.”We expect work to start in about a month’s time as the product has to be imported for now.”

The trial will be done at no cost to the municipality, with the respective partners set to foot the bill.
