Back-Calculation of Binder Properties in Asphalt Mixture Containing Recycled Asphalt Materials
AbstractIn this paper, the effect of adding Reclaimed Asphalt Pavement (RAP) and Recycled Asphalt Shingles (RAS) on low temperature properties of recycled asphalt mixtures is investigated through Bending Beam Rheometer (BBR) tests. A back calculation transformation, derived from analogical modeling of rheological behavior, and a micromechanical model are used to predict the asphalt binder creep stiffness from mixture experimental data. The, results are then compared with the experimentally determined BBR creep stiffness on extracted binders. Results indicate the addition of RAP and RAS significantly affects low temperature performance and the effects are related to mixing and blending processes
