CRCP on the Ben Schoeman Freeway – No Alternative

For the commuter traveling between Pretoria and Johannesburg, the name “Ben Schoeman” nowadays has become synonymous with traffic congestion and delays. Towards the end of the previous century, the Ben Schoeman was already the busiest road on the African continent with the Average Annual Daily Traffic on some road sections close to 150 000. For the South African Civil Engineer, however, the Ben Schoeman can be viewed from a totally different perspective as it is the only continuously reinforced concrete pavement (CRCP), of substance, in the country. The increasing traffic volume and a traveling public becoming more and more environmentally conscious, but intolerant to traffic delays, was only one of the issues facing the Engineers who, once again, had to develop an innovative long-lasting concrete pavement repair solution. Considerable research went into developing and testing rapid repair concrete mix designs as the worldwide philosophy on freeways is: Get in, get out and stay out. The CRCP has proven to be a low-cost high-benefit solution with only 0.2% of the pavement surface area requiring local repair work after nearly 20 years of service. The paper gives an overview of the history of the Ben Schoeman, the investigation into the CRCP over a number of years and the fast track concrete repair measures implemented during a recent repair contract. A comparison is made between the behavior of the CRCP and that of jointed concrete pavements (JCP) over time.
