Abstract

The Full-Depth Reclamation (FDR) technique is a cold-mix asphalt (CMA) technology employed in New Mexico to rehabilitate existing pavements. It results in minor disruption to traffic, environmental advantages, and decreased construction period and costs. However, insufficient data on the material properties of FDR mixtures and their characterization limits the use of the mechanical-empirical (M-E) design method of FDR materials. The MEPDG develops performance models using the structural response of pavement layers to predict pavement structure systems based on material properties, climate models, and loading conditions. This study has developed MEPDG models to predict the long-term performance of FDR materials and ensure that the pavement design of FDR materials is dependable and efficient. Several tasks were performed in the laboratory to characterize and determine FDR materials' mechanical and performance properties. Two MEPDG models were developed to justify and validate the hypotheses of this study: Mr and |E*| input parameters.
