During the pavement construction, traditionally, epoxy asphalts need heating and operation at constantly high-temperatures. Consequently, a great amount of toxic gases and harmful components are released into the atmosphere, which leads to not only pollution of the environment but also produce annual escalation of energy consumption. Compared to traditional hot mixed epoxy asphalts, cold-mixed epoxy asphalts (CMEA) is an emerging technology. CMEA cure at room or lower temperatures, which do not need a heat source for mixed, and also have a relatively highly workable and has good bonding between the materials in the mixture. Additionally, the engineering benefits of CMEA technology include reduce energy consumption, decrease greenhouse gases and better mixture compaction, during the construction as an environmentally friendly technology. In present study, epoxidized soybean oil (ESO) has been grafted polymerization onto nano SiO2 surface, and then modified Nano-silica solubilizer was applicated to the cold-mixed epoxy asphalt for raised the compatibility of CMEA, which were observed by fluorescence microscope (FM) and differential scanning calorimetry (DSC). Furthermore, conducted MD simulation to comprehensively evaluate the compatibility properties of CMEA were also investigated.
