Evaluation of Crumb Rubber/SBS Modified Asphalt Binder and Mixture (124048) Introduction

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. Evaluation of Crumb Rubber/SBS Modified Asphalt Binder and
