Fatigue damage property of permeable friction courses under the water-temperature-load coupling action

In order to investigate the fatigue damage property of permeable friction courses (PFC) under the coupling action of water, temperature and load, the PFC with length of 2.93 m, width of 1.10 m and thickness of 0.04 m was prepare in the laboratory and tested by the accelerated loading testing system MMLS3. The profilometer and the portable seismic properties analyzer (PSPA) was utilized to measured the rutting depth and modulus of the whole asphalt pavement, respectively. It is found that the PFC is compaction-type rutting. In the position 200 mm, the modulus first increases and then decreases. The excess pore water pressure is not measured in pavement. The results can provide beneficial references for the design, construction and fatigue damage analysis of PFC.
