SBS modified asphalt chemical properties

• SBS-modified asphalt uses styrene-butadiene-styrene block copolymer (SBS) as a modifier.
• Through physical blending, a thermoplastic elastomer network structure is formed, significantly improving the asphalt's weather resistance, elasticity, and fatigue resistance.
• Its chemical stability ensures no significant performance degradation during hot storage, making it suitable for harsh environments.

Advantages of SBS modified asphalt

• High-temperature stability: SBS modified asphalt has a softening point of 40-50℃, about 15℃ higher than base asphalt, effectively resisting rutting deformation.
• Low-temperature crack resistance: Its ductility exceeds 1.5 meters, 3-5 times that of base asphalt, reducing the risk of low-temperature cracking.
• Enhanced durability: The carbonyl index increase after aging is reduced by 30%, improving UV resistance and extending pavement service life.

Application scenarios of SBS modified asphalt

 

High-grade roads: Used in the surface layer of highways, reducing rutting depth by 58%.

Special environments: Suitable for bridge expansion joints (elastic recovery rate >85%) and airport runways (increased shear deformation resistance by 45%).

Extreme climates: Performs excellently in extremely cold or hot regions; graphene/SBS composite modified asphalt further enhances high and low temperature performance.
