High-viscosity high-elasticity asphalt based on surface modification of rubber particles, and high-viscosity high-elasticity SMA (stone mastic asphalt) mixture based on surface modification of rubber particles and preparing method thereof
The invention discloses high-viscosity high-elasticity asphalt based on surface modification of rubber particles, and high-viscosity high-elasticity SMA (stone mastic asphalt) mixture based on surface modification of rubber particles and preparing method thereof. The high-viscosity high-elasticity asphalt is made from base asphalt, activated rubber powder, a weatherable component, a tackifying component, a plasticizing component, a compatibilizing component and a cross-linking component according to a mass ratio being 100:(15-20):(4-6):(2-4):(1-3):(1-5):(0.1-1). By applying the high-viscosity high-elasticity asphalt to the production of the SMA mixture, performances of the mixture, such as ageing resistance, low temperature performance, high-temperature performance and fatigue resistance. The technical problem that the composite modified asphalt with low amount of rubber powder is difficult to use in asphalt concrete is solved; the high-viscosity high-elasticity asphalt and the high-viscosity high-elasticity SMA mixture are suitable for popularization and application.
