In this paper, based on pass-to-coverage ratio and power spectral density, which are the major factors of the airport pavement, we separately construct the carrying capacity mathematics model of airport pavement and the accidental degree mathematics model of the airport pavement. Then based on fuzzy mathematics, we propose the evaluation method of the airport pavement. Then, this thesis selects three domestic airports as the evaluation samples, makes imitation analyses based on actual data, and achieves identical results with the current operation situation of the plane. Also, the evaluation method is an effective mathematics description of the airport pavement condition and gives clear evaluation result according to the computer simulation. The method above gives suggestions to the airport pavement management.
