[Abstract]:With the continuous extension of the road network in our country, the traffic volume of the road increases rapidly, and the maintenance work of the road surface becomes more and more serious. The maintenance of the road surface is in urgent need of high performance repair materials which are not restricted by the climatic conditions. As an excellent repair material, waterborne epoxy emulsified asphalt mixture can quickly repair the pavement at room temperature. Therefore, the study of epoxy emulsified asphalt and its mixture is carried out in this paper. According to the current research situation and existing problems of waterborne epoxy emulsified asphalt and its mixture, the main research in this paper is as follows:. (1) the fatty acrylic resin (PF5233), which gives flexibility to epoxy resin, was selected as toughening modifier for epoxy resin, and the polyamine curing agent T450 was used as curing agent for flexible resin system. The emulsifier PF108 is used as emulsifier to prepare waterborne epoxy emulsion. According to the purpose of this experiment, the curing time is considered. The composition of E-51 / PF5233C-1 / 1 is considered as the formulation of epoxy system in the binder of mixed mixture, the waterborne epoxy emulsion is prepared by reverse conversion method, and the PF108 emulsifier is used. The microcosmic morphology of waterborne epoxy resin emulsion was observed by electron microscope. The results showed that the epoxy resin distributed uniformly in the medium water. 2 through the analysis of emulsification mechanism and emulsification conditions of emulsified asphalt, anionic emulsifier U-58 was selected as asphalt emulsifier, and its dosage was 1.1. The microscopic morphology of emulsified asphalt was observed by electron microscope. The results showed that the emulsifying effect was better. (3) by analyzing the modification mechanism of modified emulsified asphalt and comparing its preparation methods, the effects of waterborne epoxy resin emulsion, curing agent and emulsified asphalt on the performance of epoxy emulsified asphalt were analyzed. The results show that when the ratio of waterborne epoxy emulsion to emulsified asphalt is 1: 1, the curing time meets the experimental requirements, the tensile strength is strong, and the elongation at break meets the standard requirement. On the basis of preparing waterborne epoxy emulsified asphalt, the mixture ratio of epoxy emulsified asphalt mixture is optimized and its road performance is studied systematically. Epoxy emulsified asphalt mixture has good high temperature stability, water stability and low temperature performance, and open traffic time to meet the construction requirements. 5. The influence of emulsifier dosage, water consumption, filler and mixing condition on the construction performance is discussed, and the corresponding points for attention are put forward.
