This paper proposes the construction of an emergency restoration system for the damage caused to the airport asphalt pavement during an earthquake disaster. In the process, first, the damage (crack) caused by the earthquake and the effect of subsequent repair work are evaluated from a structural point of view, and then an emergency restoration method is examined. For the former, the deflection is measured using a falling weight deflectometer (FWD) in the cracked and healthy parts. For the latter, the materials must be permanently stored in the airport and large-scale equipment and machinery must be used when using them. In order to use a method that can be easily manufactured and installed, we conducted laboratory tests and experimental construction. As a result, the method shown below was considered to be appropriate as an emergency restoration system for airport asphalt pavement.
(1) As a method for repairing steps and depressions, we considered a large-scale construction method using simple machines and a small-scale method using human power. Powdered asphalt heated mixture is suitable for the former, and resin-based room-temperature mixture is suitable for the latter.
(2) As a crack repair method, it is suitable to use asphalt-based room-temperature injection materials, which are particularly excellent in terms of filling.
