With the age of asphalt pavement, the service function of asphalt pavement is degraded by cracking,rutting and roughness. In particular, the reduction in bearing capacity of the base course due to rainwater infiltration from cracks has a significant impact. On the other hand, asphalt pavement is required to maintain its function for a long period of time and to reduce management costs. In this study, geotextiles were installed in the base course to improve the bearing capacity of asphalt pavement and to investigate countermeasures against rainwater infiltration by cracks. In this paper, the effect of rainwater infiltration on the bearing capacity and deformation of geotextile-loaded ground is investigated by conducting loading tests in a small soil box. The results showed that the reduction in the bearing capacity of the base course with rainwater infiltration was suppressed by laying geotextile, which was effective in improving the durability of the pavement.
