Influence of Bitumen Chemistry and Crumb Rubber Pre-Treatment on the Storage Stability and Rheological Performance of Modified Binders
The incorporation of crumb rubber (CR) into bitumen offers significant performance and sustainability advantages, yet its widespread adoption is impeded by poor storage stability caused by thermodynamic incompatibility. To address this fundamental challenge, this study investigates the role of bitumen chemistry, specifically the balance of fractions determined via SARA analysis, and the efficacy of crumb rubber pre-treatment in creating a stable binder system. Two base bitumen with distinct chemical compositions (P …
