The feasibility of using concrete containing recycled asphalt pavement (RAP) in concrete pavement applications was evaluated. Recycled asphalt pavement (RAP) is the removed pavement material containing asphalt and aggregate. However, limited researches have been done to examine the potential of incorporating RAP into concrete. Since RAP contains asphalt, it is very likely that the toughness of concrete made with RAP could be improved. An alternative use of RAP is to use it as an aggregate in Portland cement concrete (PCC). Concrete containing 0%, 15% and 30% of RAP replacement by weight of natural coarse aggregates with different cement content with (250, 300 and 350 kg/m3) were produced in the laboratory and evaluated for their properties that are relevant to performance of concrete pavements. Mechanical properties of the concrete mainly compressive strength, modulus of elasticity and Poisson’s ratio after 28 days were recorded. The test results indicated that, the modulus of elasticity was found to decrease as the RAP content of the concrete increased, due to a decrease in the compressive strength of the concrete. However, these results as RAP were incorporated in the concrete, the resulting of compressive strength to modulus of elasticity and Poisson’s ratio for the concrete was reduced as compared with mixes that of a reference concrete without RAP. This indicates that, using a concrete containing RAP could possibly result in improvement in the performance of concrete pavements. Moreover, RAP could be used into Portland cement concrete without any modification to the conventional equipment or procedures.
