South Africa has the expertise and technology to design, construct and maintain concrete roads on a par with the best in the world, according to Bryan Perrie, managing director of the Cement & Concrete Institute (C&CI). “Virtually all of the many potholes on our roads are on asphalt pavements and are essentially due to lack of maintenance. By contrast, concrete roads do not form potholes and they require significantly less maintenance. Concrete also does not form ruts and it can be used to rehabilitate asphalt roads, either by overlaying or inlaying,” says Perrie. “With their long life and low maintenance requirements concrete roads can increase the sustainability of the country’s road network. “Research has shown that when equivalent designs are compared, concrete is about 10 to 15% more expensive on initial costs. But concrete lasts much longer than asphalt and the significantly lower maintenance costs mean that in a full life-cycle cost assessment, concrete roads have a similar or lower whole-life cost.
