• Abstract:
  Based on findings from the literature review, laboratory tests, and pavement performance ; simulations, researchers concluded that the use of reclaimed asphalt pavement (RAP) in Portland ; cement concrete (PCC) is largely feasible for the pavement application. Despite the fact that ; RAP-PCC yielded reduced mechanical properties (especially different strengths), a proper ; utilization of optimized aggregate gradation benefits from using RAP and the use of RAP-PCC ; as a bottom lift in a two-lift pavement construction can compensate the strength reduction and ; allow more RAP in the mixture. An even higher amount of aggregates (both coarse and fine) can ; be replaced to make full use of RAP to make low strength PCC for the other applications such as ; curbs, gutters, sidewalks, etc. Considering the factors related to strength, materials, construction, and performance, researchers developed the following guidelines.
