Effect of rainwater infiltration from pavement surface on base course bearing capacity
Effect of rainwater infiltration from pavement surface on base course bearing capacity
Japan has a huge stock of road pavements, exceeding 1.2 million km. However, road pavements require constant maintenance and repair work because they gradually progress in deterioration due to various factors immediately after the operation. In particular, the deterioration of base course bearing capacity due to rainwater infiltration through cracks from the asphalt layer is said to have a significant impact on the durability of road pavements. However, it is difficult to observe and investigate the deterioration in the base course while it is in service, and there are only a few cases where detailed investigation and analysis have been attempted. This study reports the results of CBR tests on the effects of water content ratio at the time of sample preparation and rainwater infiltration time on the bearing capacity reduction behaviour of base course using two types of pavement materials.
