[Abstract]:The surface structure of cement concrete pavement was worn off in 1-2 years, which seriously affected the driving safety. The waterborne epoxy resin modified emulsified asphalt sand fog seal is a new type of preventive maintenance technology. The mixture composed of modified emulsified asphalt or coal bitumen base material, clay, polymer additive as the main composition of fog sealing material and sand, is laid on the road surface, It can maintain or improve the skid resistance of road surface. But ordinary modified emulsified asphalt has poor adhesion and durability. Waterborne epoxy resin is a kind of emulsion formed by dispersing epoxy resin in aqueous continuous medium in the form of particles or droplets. It has low content of hydrophilic VOC, small pollution, good stability and high solid content. The adhesion of waterborne epoxy resin modified emulsified asphalt and its sand fog sealing layer was studied in this paper, and the adhesive strength of the modified emulsified asphalt was greatly improved by adding waterborne epoxy resin into modified emulsified asphalt. The main research work is as follows: the main technical indexes of modified emulsified asphalt and waterborne epoxy resin are tested, and the curing mechanism of waterborne epoxy resin with modified emulsified asphalt is expounded. The influence of the content of waterborne epoxy resin on the properties of modified emulsified asphalt was studied. It was found that the high temperature performance, low temperature property and emulsion viscosity of modified emulsified asphalt with waterborne epoxy resin were increased significantly. The effects of the amount of waterborne epoxy resin, the particle size of sprinkled sand and the amount of sand on the wear and slip resistance of emulsified asphalt sand modified by waterborne epoxy resin were studied. The content of waterborne epoxy resin and the particle size of sprayed sand are determined as the main factors that influence the wear performance of fog sealing layer. Based on the load wear test, the content of curing agent is compared. The effect of temperature and content of waterborne epoxy resin on curing time of fog seal layer is studied. The results show that the content of curing agent and curing temperature of waterborne epoxy resin are the main factors affecting curing time of fog seal layer. Water dilution test and coarse aggregate adhesion test were used to compare and analyze the properties of waterborne epoxy resin modified emulsified asphalt fog seal layer and traditional modified emulsified asphalt fog seal layer. The results show that waterborne epoxy resin foggy seal is much better than traditional fog seal in wear performance and skid resistance, and its foggy sealing material has water dilution property and better adhesion to coarse aggregate. The economic benefits of different curing measures were analyzed. It was pointed out that the annual life cycle cost of emulsified asphalt sand sealed by waterborne epoxy resin was lower than that of traditional fog seal, and it had good economic benefit.
