| contents | <p>Crumb rubber serves as a modifier for bitumen in the production of asphaltic aggregates, utilizing either the dry or wet process. When incorporated through the wet process, crumb rubber-modified bitumen demonstrates enhanced road performance, including increased resistance to rutting and cracking, as well as a higher resilience modulus. In this study, crumb rubber was subjected to thermal pre-treatment and blended with bitumen at temperatures between 160 °C and 180 °C. Physical properties such as viscosity, softening point, penetration value, and ductility were measured. The results reveal that the addition of crumb rubber increases viscosity and elevates the bitumen's softening point. A reduction in penetration value further improves rutting resistance. However, excessive reduction in ductility may compromise resistance to low-temperature cracking. Analytical techniques, including FTIR, SEM, and DSC-TGA confirmed the improved performance of crumb rubber-modified bitumen with respect to rutting and cracking resistance.</p> |
