PERFORMANCE MODELS FOR DEEP IN SITU RECYCLED, BITUMEN STABILISED PAVEMENTS UNDER ACCELERATED TRAFFIC

Described is research to assess the use of foamed bitumen and bituminous emulsion treated materials with deep in situ recycling. Heavy Vehicle Simulator and laboratory test results on these materials are discussed. The HVS data are used to develop preliminary structural design models for effective fatigue and permanent deformation, and to determine damage factors.
