This report, sponsored by the Alabama Department of Transportation, presents the development of a non-solvent based test method for evaluating reclaimed asphalt pavement (RAP) mixes. The primary objective is to create a simple and quick test to assess binder properties using standard gyratory-compacted asphalt concrete samples. The test method involves indirect tensile creep testing, which is simpler and more efficient than traditional methods. The test uses standard gyratory samples, controlled near-ambient temperatures, and a simple load frame with an electronic load cell. The test duration is only 5 minutes per sample, making it suitable for field applications. The report outlines the steps for assessing RAP stockpile binder properties, estimating the percentage of RAP in a given mix, and selecting the appropriate virgin asphalt PG grade. It also discusses the practical applications of the findings, such as determining when to change the virgin PG grade and estimating the actual percentage of RAP used in construction. The research program includes a detailed analysis of the stress relaxation modulus and curvature coefficient, which are key parameters for evaluating binder properties. The results show that these parameters can be used to differentiate between mixes with different PG grades and to estimate the percentage of RAP. The test method was validated through field studies, demonstrating its repeatability and reliability. The report concludes by recommending further work, including adapting Marshall stability load frames for stress relaxation testing, collecting data from a wider range of HMA mixes, and verifying the test method in the field for monitoring RAP stockpile binder properties.This report, sponsored by the Alabama Department of Transportation, presents the development of a non-solvent based test method for evaluating reclaimed asphalt pavement (RAP) mixes.
