Abstract: The organic-inorganic composite pavement (OICP) is a new road material which combines the best qualities of Portland cement concrete (PCC) and asphalt concrete (AC) by means of filling the voids of the gap-graded asphalt mixture with high strength cement mortar. It has excellent performances such as high load-bearing capacity, high rutting resistance and outstanding shearing resistance. It is particularly applicable to the deck pavements, turning sections, charge stations, crossroads and climbing sections. The applications of the organic-inorganic composite pavement material is common at home and abroad, but the research of resistance to rutting and chloride salt erosion in the extreme conditions is less reported. In the paper, we firstly prepared the organic-inorganic composite pavement material, and then tested the anti-erosion effect in the freeze-thaw cycles in the laboratory. We also tested the ability of resistance to deformation under high-temperature and heavy load. The results show that the chlorine salt erosion, freeze-thaw damage and long-term overweight loads rutting resistance of OICP are much better than that of SMA. The OICP is very suitable for loading and unloading areas of container in the port or the pier, but the perfusion rate of the cement mortar should be more than 90%.
