Embodiment 1
[0036] A preparation method for deicing, antiskid, and noise-reducing asphalt pavement materials, comprising the steps of:
[0037] 1) Preparation of rubber high-viscosity and high-elasticity modified asphalt:
[0038] Rubber high-viscosity and high-elasticity modified asphalt is composed of base asphalt, modified main agent, modified auxiliary agent, viscosity-increasing component, toughening and stabilizing component,
[0039] According to the mass ratio of each component: base asphalt: modified main agent: modified auxiliary agent: thickening component: toughening and stabilizing component = 100: 3.0: 15: 2: 2, select base asphalt, modified main agent, modifying auxiliary agent, tackifying component and toughening and stabilizing component; first, heat the base asphalt to 165°C, add the modified main agent, modifying auxiliary agent and tackifying component, stir for 10min, and then Grow in the oven for 20 minutes, start the high-speed shearing machine at a speed of 5000 r...
