Abstract
Blistering of the runway surface course was found during a runway inspection at New Chitose Airport in June 2001. A more detailed survey revealed that water penetration has reduced the bearing capacity of both the surface course and the binder course below the joint, as well as the asphalt stabilization layer. Because of a working time restriction on the runway, the thick lift method, whereby asphalt is placed in a short time, was applied in combination with a large-grain asphalt mixture that can be placed at lower temperatures than usual. The study reports the causes of pavement failure and the results of measures against such failure.
