Development of a Mixture Design Procedure for Recycled Asphalt Mixtures

This report summarizes the findings of a study to evaluate the fatigue and elastic characteristics of recycled asphalt pavement materials and to develop a preliminary mixture design procedure. Mixtures with different types and amounts of additives were evaluated in terms of their engineering properties. The primary methods of evaluation were the static and repeated-load indirect tensile tests. Estimates of tensile strength, static elastic characteristics, resilient elastic characteristics, and fatigue characteristics were obtained. Preliminary findings indicate that recycled asphalt mixtures can be treated through the addition of asphalt and/or reclaiming agents to produce a material which exhibits satisfactory engineering properties as measured by laboratory tests on both laboratory-prepared specimens and field cores. Based on these results, a preliminary mixture design procedure was formulated which will allow engineers to begin to routinely design mixtures involving recycled asphalt mixtures. Future work may lead to modifications of this procedure.
