【 摘 要 】

In engineering application, a kind of SBS is often used to modify the matrix asphalt, but there is less research on the application of double SBS composite modified asphalt. This paper shows through indoor testing: 3.15% Dushanzi T161B Star SBS Modifier +1.05% LCY3501 Linear SBS Modifier +3.75% Stabilizer + Tipke 70# matrix asphalt can be made into composite modified asphalt, which the high-temperature performance, ductility and anti-aging properties can be well adapted to the high temperature characteristics of Hainan Province, and the commonly used single modified asphalt has obvious economic advantages and can be widely used in Hainan.
