The TOL super-tough additive is an independently developed high-viscosity and high-elasticity asphalt modifier featuring high dispersion, high viscosity and high toughness. The high-viscosity asphalt mixture prepared with it delivers excellent anti-stripping performance, water resistance and weather resistance, greatly improving pavement durability. It can be applied to porous drainage, anti-skid and noise-reducing pavements (OGFC, PAC, PA), colored permeable asphalt pavements, steel bridge deck surfacing, high-viscosity high-elasticity SMA pavements, stress absorption layers and other projects.
