    Abstract

    Full depth reclamation (FDR) is a pavement recycling technique that incorporates the entire pavement section to create a rehabilitated, stabilized pavement layer. This method is cost effective, environmentally friendly, and structurally viable. Unfortunately, there is some uncertainty regarding how this composite material is classified. In this study, the material characterization of FDR was explored by comparing the effect of different compaction methods on the optimum moisture content, optimum amount of foamed asphalt or asphalt emulsion, the tensile strength, and the stability of the mixture. The superpave gyratory compactor (SGC) is typically used for the compaction of HMA samples, and the Proctor hammer is the most common method of compaction for soil samples. In addition to comparing these two methods, different sized compaction molds and varying amounts of compactive effort were considered. Samples compacted with the modified Proctor hammer produced the highest dry unit weights. Although samples compacted in the SGC had higher tensile strengths. At optimum mixture proportions, moisture conditioned samples compacted with the modified proctor hammer did not reach the minimum tensile strength requirements.
