Abstract

The invention discloses a high-performance epoxy resin asphalt warm mixing agent comprising a component A and a component B, wherein the component A is composed of epoxy resin, a reinforcing agent and a coupling agent; the component B mainly comprises a flexible curing agent, an accelerant, a reinforcing agent, a toughening agent and a defoaming agent; and the mass proportion of the component A to the component B is equal to (100:250)-(100:300). High-performance warm mixing epoxy resin asphalt prepared by using the high-performance epoxy resin asphalt warm mixing agent provided by the invention has the characteristics of lower mixing temperature, high strength, better high-temperature ductility resistance and low-temperature fracture resistance, longer construction time, simple construction process, low-carbon and environment friendliness and the like and is suitable for paving pavements of roads, bridges, tunnels, airfield runways and the like. The invention discloses a preparation method of the high-performance epoxy resin asphalt warm mixing agent.

Description

technical field [0001] The invention relates to an asphalt warm mix agent and a preparation method thereof. Background technique [0002] At present, the asphalt pavement in road construction basically adopts the traditional Hot Mixture Asphalt (HMA). HMA is a hot-mixed asphalt mixture. It heats the asphalt from normal temperature to about 140°C, heats the mineral material from normal temperature to 160-180°C, and then mixes the asphalt and mineral material at a high temperature of 160°C. , the HMA temperature after stirring is not lower than 150°C. The temperature during paving and rolling shall not be lower than 120°C. Heating asphalt and mineral materials to such a high temperature not only consumes a lot of energy, but also emits a lot of waste gas and dust during production and construction, which seriously affects the quality of the surrounding environment and the health of construction workers. Therefore, it is very necessary to study a green and environment-friend...
