The mechanical and thermal property of concrete containing recycled asphalt pavement (RAP) and their application in concrete pavement are evaluated. Concrete containing 20%, 40%, 70% and 100% RAP as aggregate were produced and their property was compared with normal concrete. Results of the laboratory testing program indicated that compressive strength, splitting tensile strength, flexural strength and elastic modulus of the RAP concrete were found to decrease as the percentage of RAP increased. The coefficient of thermal expansion and drying shrinkage increased with the increasing percentage of RAP. Finite element analysis was conducted to study the performance of concrete containing RAP in rigid pavement, under critical temperature and wheel loads at middle edge of the slab. The results of RAP concrete showed that the ratio of maximum stress to flexural strength is comparable and some even smaller than the normal concrete.
