[0058] In addition, the present invention provides a method for preparing a multi-layer reinforced high-strength asphalt anti-rutting agent with the above-mentioned industrial solid waste powder as the core, including:
[0059] (1) Place red mud and boron mud in enamel trays respectively, and place them in an oven at 110±1°C to dry for 48 hours to fully dry red mud and boron mud. Preliminarily crush the dried red mud and boron mud respectively, and then grind them with a ball mill for 15-30 minutes. After sieving, the specific surface area is 360-430m 2 / kg red mud fine powder and specific surface area is 300~430m 2 / kg of boron mud fine powder;
[0060] (2) Pour red mud fine powder and boron mud fine powder into a porcelain evaporating dish, and place in a high-temperature furnace (500°C-600°C) to heat for 6-8h; then take out the porcelain evaporating dish and place it in a desiccator, and cool to Standby at room temperature;
[0061] (3) Weigh the recovered waste polyolef...
