Abstract
Asphalt pavement is widely used in airports in China. Airport pavement under the long-term action of aircraft load and environmental load which makes various problems such as structural damage and performance degradation. As a preventive maintenance measure, the fog seal has timeliness. There is the best period for fog seal and the maintenance performance will be brought into full play. There is no specification of fog seal used in airport. Since many conventional performance evaluation indexes (PCI, etc.) of airport pavement without obvious change during use fog seal. This paper proposed a single pavement performance index to determine the appropriate use time of fog seal from the aspects of pavement service life, pavement relaxation, texture depth and water permeability coefficient. And the appropriate ranges of different indexes are studied according to the treatment purpose of fog seal. The research provides decision basis for airport pavement management department to carry out preventive maintenance.
