Abstract
In this paper, influences of New Generation Large Aircrafts (NGLA) on the runway rutting were analyzed and the importance of combining laboratory performance tests and suitable analytically-based methodology was emphasized. Based on the multilayered elastic theory, the vertical compression stress distributions under different airplanes including NGLA were studied. Then the dynamic creep test was conducted to obtain the visco-plastic characteristics of pavement including three mixture types. Furthermore, the rutting depth under different airplane was predicted by employing the Shells method and the dynamic creep test results. The results showed rutting depth would be more significant by loading cycles of NGLA, compared with that by ordinary airplane. Suggestions composed of both the structural and material considerations were proposed for runway pavement design.
