Abstract:
This study was focused on evaluating the feasibility of using minimally processed reclaimed asphalt pavement (RAP) as aggregate replacement in concrete pavements. A statistical experimental design procedure (response surface methodology) was used to investigate the effects of key mixture parameters on concrete responses. The response surfaces generated from this analysis adequately characterized the behavior of these concrete mixtures, and were ultimately used to develop optimum mixtures to meet varying performance criteria. In laboratory tests, the optimum mixtures performed well and as predicted, thus validating the feasibility of using RAP in this application and this mixture design methodology.
