By comparing and evaluating the physical properties of asphalt road pavement in Cambodia and Korea, Cambodian companies will use it as basic data for future efficient management such as road pavement design, quality and maintenance management. The purpose of this study was to examine the pavement status of Cambodia’s asphalt roads through quality control cases based on overseas demonstration projects. The thickness of the asphalt layer was thinner and larger than that of Korea. on the other hand, density is generally similar. Deformation strength test results showed that neither surface layer nor base layer corresponded Korean standards. Marshall stability, flow, retained stability, indirect tension, tenacity, and tensile strength ratios were corresponded Korea’s quality standards, but not enough. The performance analysis of the asphalt core specimens showed that the overall quality standards of Korea were satisfied. However, As the thickness of the asphalt layer is rather thin and the variation is severe, it is necessary to thoroughly manage the construction and the quality fluctuation due to the thickness difference of the surface layer and the base layer will be serious.
