摘要: The permeability of porous asphalt (PA) reduces after a few years in service due to clogging. two-layer asphal (TLPA) was developed mitigate this problem. This paper presents laboratory-simulative clogging test single-layer and TLPA using falling-head water permeameter. resistance the PA specimens evaluated by subjecting five cleansing cycles. All tests were carried out at an ambient temperature. To evaluate effects temperature on resistance, procedure also conducted selected but conditioned 10°C, 30°C 50°C. results showed that significant loss took place during first cycles, beyond which it asymptotes. can better resist compared with specimens. Binder content significantly affects behaviour, while higher more susceptib...
