Abstract:

Data were collected from test road sections in the Province of Quebec, Canada, for the purpose of evaluating the effects of materials and in situ conditions on the performance of asphalt concrete pavements. These pavements were tested in 1980 to determine rutting, ride, and deflection characteristics. In situ conditions were determined by sampling and test measurements. Asphalt concrete cores were obtained for indirect tensile strength tests and for recovery of asphalt for conventional consistency tests (penetration, viscosity, and softening point). These data were compiled along with information contained in the original construction records and pavement crack surveys. Statistical analyses were conducted and various relationships were developed that relate to factors that influence asphalt binder properties, tensile strength, and transverse cracking. The most significant findings include (a) a verification of greater age hardening when in-service asphalt concrete pavements have air voids in excess of 4.0 percent, (b) a tentative test method that incorporates the work of Goode and Lufsey to evaluate the age hardening of binders, and (c) mathematical relationships developed from statistical analyses by using recovered asphalt penetration and traffic level for the prediction of transverse cracking. Results of other analyses are presented that define those variables that have an effect on consistency parameters, mix tensile strength, rutting, and ride quality. Dynaflect deflection basins were analyzed by using an elastic layer computer program, which resulted in the development of relationships between subgrade moduli and the fifth-sensor deflection.
