FRACTURE ENERGY - USEFUL MATERIAL CHARACTERISTIC IN PAVEMENT EVALUATION

Energy as material characteristic has been the basic parameter for investigating material behaviour under fatigue. Such an approach to explain pavement behaviour under traffic has not been commonly adopted so far. This paper presents the development of the concept of fracture energy as the parameter representing the overall state of a pavement at any stage of its life. A hypothesis is presented for the application of the energy concept in pavement evaluation. A mathematical relation between fracture energy and remaining life is also derived. For the covering abstract see TRIS 450963. (TRRL)
