Waterborne epoxy resin was used to modify emulsified asphalt.The physical properties of modified emulsified asphalt with different waterborne epoxy resin dosage were investigated.The optimum dosage was determined according to the actual performance requirements of antiskid composite sealing material.The structure and properties of emulsified asphalt modified by waterborne epoxy resin were characterized by infrared spectroscopy,DSC and TG.The results shown that the hardness,adhesion,peeling strength,tensile strength and low temperature flexibility of the modified asphalt were greatly improved when the content of waterborne epoxy resin was 30%,and the heat resistance and frost resistance were also obviously improved.Infrared spectrum shown that the waterborne epoxy resin and emulsified asphalt was ideally hybrid.The waterborne epoxy resin was used to modify the emulsified asphalt.The antiskid and water-proof properties of the pavement constructed with antiskid composite seal were obviously improved.
