Performance evaluation of asphalt binder and mixture modified by pre-treated crumb rubber
Highlights Pre-treatment changed the chemistry, hydrophilicity, and morphology of crumb rubber. Modification effects by crumb rubber were more significant after pre-treatment. The developed asphalt mixtures exhibited excellent road performance. The developed asphalt mixture was successfully applied in two practical projects.
Abstract This work presents a laboratory and field study on the performance of the asphalt binder and mixture modified by pre-treated crumb rubber. Initially, a mechano-chemical method was employed to pre-treat crumb rubber, intending to increase its surface activity and compatibility with asphalt binder. Subsequently, the properties of asphalt binders and mixtures modified by the pre-treated crumb rubber were evaluated systematically. Test results showed that the incorporation of pre-treated crumb rubber resulted in the reduced penetration value, higher softening point, enhanced tensile performance, improved elastic recovery, and greater aging resistance of asphalt binder. Additionally, the asphalt mixtures modified by pre-treated crumb rubber demonstrated excellent road performance. Furthermore, the developed asphalt mixtures were successfully applied in practical engineering, validating the feasibility and practicality of the modified asphalt mixture by pre-treated crumb rubber.
