Styrene Butadiene Rubber (SBR) Particle asphalt modifier is a high-performance polymer elastic material. By adding SBR particles according to highway grades, it modifies asphalt characteristics through appropriate grafting of monomers to produce a network-structured material. This high ductility asphalt modifier subverts traditional road SBR modification status.

Compared to block rubber, SBR particles offer significant advantages: less addition required, short dissolution time, and superior anti-aging performance. It creates a stable shell-core structure in modified asphalt without needing additional stabilizers. It excels in low-temperature performance, making it particularly suitable for high-altitude and cold regions.
