Material Design and Property of High Viscosity Asphalt Used in Pervious Asphalt Pavement

Abstract:

Dynamic viscosity, toughness and tenacity were used as the key indicators combined with conventional asphalt indicators such as ductility, penetration, softening point to evaluate the modification effect. The change laws of the indicators influenced by the dosages of polymer, compatilizer and stabilizer as well as the modification mechanism were analyzed; and the dosages of the three modifiers were determined. The results indicate that the modification effect is strongly influenced by the content of modifiers. Each of the modifiers plays a unique role in the performance the high viscosity asphalt. Through a particular modification technology, the optimum dosages of polymer, compatilizer and stabilizer used in self-modified high viscosity asphalt were determined at 7%, 3% and 2% respectively.
