This kind of modifier can significantly improve asphalt viscosity, asphalt mixture high-temperature stability (anti-rut capacity), fatigue resistance, water stability and low-temperature cracking resistance.
1)Porous asphalt pavement
2)Rigid bridge pavement，paving asphalt mixture on old cement concrete pavement
3)Heavy-traffic roads and roads which are easy to rut under heavy load.
3.Product usage amount and methods
1)Premixing: heat heavy-traffic asphalt to 185℃, add 10% DS-SHV high-viscosity asphalt modifier, and shear for 25～30min at high speed.
2)Direct distribution: Add DS-SHV high-viscosity asphalt modifier while adding aggregates to mixing pot according to the usage ratio, add asphalt based on asphalt-aggregate ratio, and mix the materials for 40～45s.
