The development of grey water resistant asphalt

The City of Cape Town noted that bituminous surfacings on various roads in informal settlement areas needs to be repaired or replaced at least every 5 years. Closer investigation has shown that most of the serious failures are located in areas adjacent to communal standpipes or in areas where people dispose of “Grey Water” on the road. Mew Way in Khayelitsha was identified as a particularly problematic example of this phenomenon to investigate and to find appropriate solutions. The paper discusses the typical damage caused by Grey Water, background to identify potential solutions based on the performance of different compositions of asphalt mixtures in the laboratory testing phase as well as additional research required and the way forward.
