ASPHALT OVERLAYS IN RESIDENTIAL STREETS: DESIGN CONSIDERATIONS

Asphaltic concrete (ac) overlays have proven to be an economic and durable method of pavement rehabilitation. Residential street conditions are significantly different to highways, and overlay procedures developed to suit the highway have little significance in residential streets, where other than load factors have greater influence on performance. Significant improvement in ac overlay performance can be achieved by simply increasing the bitumen content of conventional continuously graded ac mixes, to give surfacings with potentially double the service life of ac mixes used in the past. The economic benefits to the community are potentially significant, if rehabilitation decisions are made utilising a management system. Expedient, low first cost rehabilitation options must not be adopted wittout carful thought to overall cost. (TRRL)
