What technical requirements define asphalt modified by sbs triblock copolymer structures and properties for asphalt or bitumen modification?

The technical requirements for asphalt modified by SBS triblock copolymer include enhanced elasticity, improved temperature susceptibility, and increased resistance to deformation and aging. The SBS modification should meet specific performance criteria such as viscosity, softening point, and penetration grade. Additionally, the modified asphalt must exhibit superior adhesion properties and durability under various environmental conditions. Compliance with relevant standards, such as ASTM or AASHTO, is essential to ensure the quality and performance of the modified bitumen.
