High viscosity asphalt
WebApr 2, 2014 · High viscosity asphalt binders (HVABs) were developed by Japanese companies to improve rutting resistance and durability of porous asphalt [ 15 ]. HVABs are compound modified asphalt binders, which are mainly modified by styrene–butadiene–styrene (SBS), mineral oil and petroleum resin [ 9 ]. WebThick stiff fluids such as asphalt rubber have high viscosity; water has low viscosity. Viscosity is specified as a measure of field quality control for asphalt rubber production and its use in RAC mixtures.
