Abstract The compatibility between crumb rubber (CR) and asphalt binder plays a key role in the storage stability and rheological performance of rubberized asphalt binder. This review provides a comprehensive overview of characteristics of rubberized asphalt binder, factors influencing compatibility, compatibility evaluation methods, and improvement approaches. Desired compatibility results from the fact that CR is cross-linked with molecules of asphalt binder and evenly distributed in the asphalt binder, forming a homogeneous system. Rheological methods are the most widely used methods for compatibility evaluation. Additionally, the hybrid processing of surface activation treatment of CR and additives-grafting has shown to be a promising method for improving the compatibility of rubberized asphalt binder.
