SBS is a well-known elastomeric polymer used to improve the elasticity, viscosity, and temperature susceptibility of asphalt binders. However, the integration of Crumb Rubber (CR)—derived from recycled tires—into SBS-modified asphalt is a crucial approach to improving sustainability. This combined modification (CR/SBS) offers a synergic effect, where the elasticity of SBS and the filling/reinforcing properties of the crumb rubber improve the pavement's resistance to permanent deformation and fatigue cracking.

While swelling improves properties, excessive aging or improper manufacturing can lead to the degradation of the crumb rubber, affecting the long-term performance of the asphalt. Studies like the one cited focus on optimizing this balance. SBS is a well-known elastomeric polymer used to

The interactions between the rubber particles and the SBS copolymer change the morphology of the asphalt binder. When properly blended, the rubber particles swell, absorbing the lighter components of the bitumen, which increases the viscosity of the mastic. Key Findings in Binder Investigation mentioned, such as
