Abstract: It is difficult to repair or achieve a satisfactory repair effect because of the non-stop flight regulation and cement concrete deformation characteristics under load. Epoxy resin (epoxy value is 0.44) and polyamide resin are used as curing agent. Glass layer, mica powder, alumina, titanium oxide are used as fillers of pavement surface thin layer repair materials. Performance indices of the four proportioning schemes are tested including BPN, impact resistance, wear resistance (TD value) and durability. Testing result shows that the BPN of the thin layer repair material under the designed proportioning is increased by 14%~27%, the impact resistance is increased by 140%~320%, TD values of all the four proportion schemes are more than 0.7, and all the loss rates of high temperature and freeze-thaw tests are less than 2%, the second proportioning scheme has the best comprehensive properties.The test result can provide technical reference for the proportion of airport pavement thin layer repair material.

Key words: airport pavement, thin repair material, material proportioning, performance testing
