Abstract
The solutions against the problems found as a result of applying Airport Pavement Optimal Rehabilitation Timing System (AirPORTS) to the asphalt pavements of some airports being studied, advanced version of AirPORTS has been being developed. The points taken into consideration this time were the following three. As the items for pavement performance evaluation, cracking, rutting and roughness are included in addition to PRI, and the fatigue damages of both asphalt mixtures and subgrade are also included. For quantifying the change of pavement performance, various kinds of curve models other than a straight line model are introduced. Furthermore, prolongation of the planning period and types and number of operations of aircraft are arbitrarily selected.
