In the hot-mix epoxy asphalt concrete steel bridge deck pavement system, the production of epoxy asphalt binder is an important link, the epoxy resin binder, asphalt and mineral aggregate need to be added in the production process and are fully stirred and mixed together, and the proportion of the epoxy resin binder to the asphalt is 1: 1. the epoxy resin binder consists of two materials, namely a main agent (epoxy resin) and a curing agent, wherein the ratio of the main agent to the curing agent is 56: 44, preheating the barreled main agent and curing agent to a temperature range of 60 +/-5 ℃ before use so as to ensure the optimal mixing effect and construction timeliness. When the binder is produced, the main agent and the curing agent are mixed according to the barrel number of the production dosage of each plate according to the proportion of 56: the mixture is fully stirred and mixed in a proportion of 44 (generally, the barreled weight of the main agent and the curing agent is packed according to a proportion of 56: 44, and the barreled weight is equal to the proportion of 1: 1 in barrels), and then the mixture and the matrix asphalt are synchronously put into a stirring cylinder of an asphalt mixing plant to be stirred and mixed with mineral aggregate.
