Road research in progress at ARRB: part i - recent research on bituminous surfacings; part ii - research in progress of particular relevance to tropical regions

Part i of this paper describes briefly recent ARRB research into the effect of the environment on the performance of bituminous surfacings. It shows that hardening is related to maximum temperatures and the onset of distress is related to minimum temperatures. The use of rubber to improve the elastic recovery of seals and asphaltic concrete is being investigated with initial studies of particle size, time of digestion and method of production of rubber crumb. Skid resistance measurements to establish seasonal and temperature correction factors are described. Part ii discusses selection of research topics, resource allocation, research management and dissemination with examples of current ARRB work relevant to tropical regions. The technical committee structure is outlined and its part in generating studies exemplified in residential street research and studies of overtaking. The instrumentation support needed by a research group is mentioned and the ways of providing for the application of research are listed (a).
