Embodiment 1
[0028] Warm-mix high modulus asphalt mixture additives include the following components by weight, 10 kg of polymer organic wax, 25 kg of thermoplastic elastomer polymer polypropylene, 5 kg of waste truck tire rubber powder (30 mesh), KH~550 5 kg of silane coupling agent, 5 kg of inorganic filler cement, 7 kg of anti-aging agent p-diphenylamine and 40 kg of hard asphalt.
[0029] The preparation process of warm-mix high-modulus asphalt mixture additives is as follows: First, use the auxiliary device of the silo, that is, the electronic metering device to accurately weigh the content of each component, and then control the content of each component in the silo according to the proportion of the components. The feeding speed and the inclination angle of the feed chute, each component is introduced into the feed hopper of the screw extruder through the feed trough, and the mixed components enter the screw extruder through the funnel for mixing, and are extruded by the extruder. A...
