Abstract
The role of an airport during and after a great earthquake is important as helpful existence for emergency medical service and special operation for transporting relief supplies to the stricken area. In this paper, a full-scale experiment using controlled blasting technique conducted at the Ishikari Bay New Port in Hokkaido Island, Japan, is discussed. The purpose of the experiment is to assess the performance of prototype runway pavement subject to liquefaction due to a large earthquake. Ground-penetrating radar and differential leveling before and after blasting investigated nondestructively the damage status of asphalt concrete including roadbed and underground occurred by the liquefaction. The investigation result revealed that aspects of the damages between asphalt concrete and roadbed were different.
