The technical maintenance quality of micro-surface for airport pavement is for the performance of its agglutination material to decide. In order to clarify the effect of water-based resin polymer content on the rheological properties of modified emulsified asphalt for micro-surfacing, WER/WPU modified emulsified asphalt and WER/WPU/EVA modified emulsified asphalt for micro-surfacing are prepared. With the help of dynamic shear rheological test, linear amplitude scanning test and bending beam rheological test, the high temperature deformation resistance, medium temperature fatigue performance and low temperature creep characteristics of modified emulsified asphalt under different water-based resin polymer content are proved. The rheological properties of WER/WPU modified emulsified asphalt and WER/WPU/EVA modified emulsified asphalt are compared and analyzed. The anti-deformation and anti-cracking ability of the modified emulsified asphalt in the existing research are compared and evaluated. The results show that the high temperature deformation resistance, medium temperature fatigue life and low temperature flexibility of emulsified asphalt material are effectively improved after resin polymer is being added, and the improvement range increases with the increase of water-based resin polymer content. The high temperature deformation resistance of WER/WPU/EVA-15 modified emulsified asphalt is slightly better than that of WER/WPU-15 modified emulsified asphalt, but its fatigue characteristics and low temperature crack resistance are slightly lower than that of WER/WPU-15 modified emulsified asphalt. The resin-based modified emulsified asphalt developed in this paper is significant advanced.
