[0002] In recent years, with the rapid construction of large-span highway steel bridges in my country, epoxy asphalt concrete paving scheme, as one of the most commonly used paving schemes for steel bridge deck paving, has been increasingly used. Epoxy asphalt binder is mainly composed of epoxy resin component, epoxy curing agent component and asphalt. When producing epoxy asphalt mixture, asphalt is measured by asphalt mixing plant and pumped into asphalt mixture mixing tank. Epoxy resin component and epoxy curing agent component are generally mixed and put in semi-automatic and semi-manual way. The specific method is: epoxy resin component and epoxy curing agent component are packaged separately according to proportion, firstly, epoxy resin component and epoxy curing agent component are placed in heating shed and heated separately, and then corresponding epoxy resin component and epoxy curing agent component are poured into the agitator at the same time, and after mixing evenly, they are pumped to the mixing tank of asphalt mixing plant through conveying pipeline.

[0003] The main disadvantages of the existing approach are: (1) the number of workers required to carry and pour the materials into the agitator is huge; (2) the agitator is located at the bottom of the asphalt mixing plant, and the pipeline for transporting the mixed epoxy resin to the mixing tank is more than 15 meters long. After each round of epoxy asphalt mixture production is completed, the mixed epoxy resin in the pipeline cannot be recovered, resulting in great waste; (3) the mixed epoxy resin in the pipeline is constantly undergoing a curing reaction, and there is a high risk of pipeline blockage during the production of epoxy asphalt mixture.
