Tn order to improve the shortcomings of airport pavement repair mortar, such as high brittleness and poor bonding performance, a kind of quick mortar was prepared by using waterborne epoxy resin (WER), polypropylene (PP) fiber and sulfoaluminate cement (SAC), and its working performance, mechanical properties, damping properties and sulfate corrosion resistance were studied. The results show that PP fiber and WER can significantly improve the toughness and bonding properties of the quick repair mortar, making the 2 h compressive and folding strength and bonding strength of the quick repair mortar reach 22.3, 5.1 and 3.7 MPa respectively, meeting the requirements of civil airport specifications, and improving the damping performance and sulfate erosion resistance of the quick repair mortar.
