Abstract
To promote waste tire recycling in the asphalt industry, high-content crumb rubber-modified asphalt (CRMA) has received increasing attention. This study integrates binder- and mixture-level evaluations to clarify how crumb rubber (CR) content, thermal storage, and production parameters influence binder rheological behavior, and how CR content alone affects mixture performance. Binder performance was evaluated using the Dynamic Shear Rheometer and Bending Beam Rheometer tests, while mixture performance was assessed in terms of rutting, cracking, and moisture damage resistance. The results show that CRMA significantly improves binder performance across high-, intermediate-, and low-temperature regimes. All CRMA mixtures demonstrated excellent cracking resistance. Notably, higher binder-level rutting indices did not consistently translate to superior mixture rutting resistance, while lower low-temperature performance grades correlated well with improved cracking performance. Overall, high-content CRMA provides balanced mixture performance and supports sustainable pavement applications.
