Investigation into these modified binders often focuses on their morphological properties, rheological characteristics, and swelling-degradation behavior. Key findings in this domain include:
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.

Evaluation of Crumb Rubber/SBS Modified Asphalt Binder and Mixture (124048) Introduction
The modernization of transportation infrastructure relies heavily on the advancement of asphalt technology to create more durable, sustainable, and high-performance pavements. Traditional bitumen is often insufficient to meet the demands of high traffic loads and extreme temperature fluctuations. Consequently, the modification of asphalt binders using polymers and waste materials has become a critical area of study. A significant contribution to this field is the research identifying the swelling-degradation degree of crumb rubber in SBS (Styrene-Butadiene-Styrene) modified porous asphalt, often cited within studies such as Ren et al. (2021). The Role of SBS and Crumb Rubber Modification
