Why Styrene Ethylene Butylene Styrene is the main raw material for asphalt modification

For road construction and maintenance, the performance of asphalt will affect the service life, safety and comfort of roads. Styrene Ethylene Butylene Styrene (SEBS), with its unique structure and excellent performance, has become the main raw material for asphalt modification.

SEBS is a thermoplastic elastomer, formed by block copolymerization of Styrene, Ethylene, Butylene and Styrene. This special molecular structure endows it with many properties suitable for asphalt modification.

Firstly, SEBS can significantly enhance the high-temperature stability of asphalt, enabling the modified asphalt to maintain good strength and stability at high temperatures and effectively reducing problems such as rutting. Moreover, SEBS can improve the low temperature crack resistance of asphalt, make it still have certain elasticity and ductility in low temperature environment, reduce the generation of pavement cracks, and improve the frost resistance of roads.

SEBS has good resistance to oxidation and ultraviolet aging. When added to asphalt, it can slow down the aging speed of asphalt. SEBS has good compatibility with asphalt. During the modification process, SEBS can be evenly dispersed in the asphalt, ensuring the quality stability of the modified asphalt.

SEBS has many excellent properties, which make it an ideal raw material for asphalt modification, and it is widely used in the construction and maintenance of important transportation infrastructure such as highway runway.
