Abstract In order to reduce the stability damage of the underlying permafrost caused by asphalt pavement in Qinghai-Tibet area, an original creation of heat-shielding coating (HSC) was put forward in this work. By a self-developed cooling effect testing device, the optimal coating structure was selected and the optimum adding amount of the functional materials was determined. We also investigated the depth dependence of cooling effect, and by employing pendulum type frictiograph test and MMLS3 load-accelerating equipment, evaluated the anti-skid performance and wear resistance of the coating. The results show that the optimal coating structure is CHSC with a combination of an upper reflective layer and a lower insulative layer, which can reduce the surface temperature by 12.75 ℃. Moreover, the upper layer of CHSC mixed with 15% (PVC) reflective functional materials and the lower layer of CHSC mixed with 10% (PVC) insulative functional materials are recommended. CHSC can reduce the temperature by 9.6 ℃ at the depth of 5 cm and by 6.7 ℃ at the depth of 10 cm. The ceramic particles spread in the coating act as an anti-skid material, and the amount of 0.8 kg/m² can make CHSC achieve satisfactory anti-skid performance and wear resistance which are adequate for the requirement of pertinent standards. Our work can provides reference for the solution to the underlying permafrost problem in Qinghai-Tibet Area.

Key words： Qinghai-Tibet area asphalt pavement compound heat-shielding coating (CHSC) hollow glass bead wear resistance
