Abstract
Due to heavier aircraft loading conditions, the durability of airport asphalt pavements must be increased. In addition, the fast and efficient construction method of asphalt concrete is required, especially in overlay works. As the measure to accomplish these requirements, the thick lift construction method using conventional asphalt concrete for airport pavement surface course is considered herein. Through a series of researches, mechanical properties of the thick lift-constructed asphalt concrete, and the bearing capacity and surface characteristics of the resultant pavement are found to satisfy the specification even when 10cm thick layer is constructed in one lift. In conclusion, the applicability of thick lift construction method in actual projects was verified.
