This study aims to investigate promising mitigation strategies for improving the cracking performance of high recycled binder ratio (RBR) asphalt mixtures. Moisture-resistant aggregates that do not require anti-stripping agents, reclaimed pavement (RAP), and shingles (RAS) were sampled this from sources in two climatic zones, south north. The south-moisture-resistant (SR) mixtures designed with 0.16 0.29 RBRs RAP, while north-moisture-resistant (NR) included 0.21 0.37 RAP 0.44 RBR RAP/RAS....
The economic and environmental benefits of incorporating recycled asphalt materials (RAMs) into new mixtures are achieved only if the durability is maintained. This study, conducted under National Cooperative Highway Research Program project 09-65, aims to evaluate with high RAM contents, considering component materials, mitigation strategies, balanced performance. evaluation included existing mix designs variable contents typically produced in each U.S. climatic zone (north/freeze south/no...
The IDEAL cracking test (IDEAL-CT) (ASTM D8225) provides a fracture mechanics-based parameter: tolerance index or CT Index which is sensitive to specimen thickness and air void (AV) content. of field cores with variable thicknesses AV contents are not comparable those laboratory-compacted specimens prepared at specified values. This study analyzed the sensitivity these features by preparing reheated plant-mixed (RPMLC) content developing correction factors. factors were obtained using...
