FATIGUE CRACKING OF ASPHALT PAVEMENTS

This paper validates a theoretical expression for the rate of fatigue crack propagation experimentally for asphalt concrete and sand asphalt beams supported on an elastic solid. The properties of the materials were determined experimentally from fracture tests on simply supported beams, and the rates of crack propagation under fatigue loading were determined from fatigue tests on the beams that were supported on an elastic solid. The results for the rates of crack propagation predicted from the fracture tests were then compared with those obtained experimentally; they were found to be in reasonable agreement. The theory is then usued to predict the fatigue life of a full-depth asphalt pavement. The result appears in reasonable agreement with the expected life for such a pavement.
