Abstract:

Statistical sampling plans were developed for obtaining samples of reclaimed asphalt concrete from the roadway prior to recycling, from trucks transporting processed reclaimed asphalt concrete, and from stockpiles of materials to be used for hot-mix recycling. The plans were tested on five recycling projects. Physical and chemical tests were run on aged asphalts, salvaged binder from reclaimed asphalt concrete, recycling agents, and blends of the materials. It was found that for a wide range of typical asphalts and recycling agents, an asphalt viscosity blending chart could be used to establish proportions of aged asphalts and recycling agents to produce a blend of materials generally meeting standards. Detailed test procedures, based on National Cooperative Highway Research Program Reports 192 and 246, "Predicting Moisture-Induced Damage to Asphaltic Concrete," were developed for determining the effects of water and freeze-thaw on the indirect tensile strength of recycled asphalt mixtures. Use of this test on materials from five recycling construction projects indicated that the procedures should be useful for determining moisture damage susceptibility. Detailed procedures were developed for designing hot-mix recycled paving using Marshall and Hveem test apparatus. Tentative mix design criteria are proposed based on studies of the mix design procedures using materials from five recycling projects and from tests on cores from these projects.
