AI Technical Summary
Traditional impermeable pavements cause water accumulation on the road surface, reducing vehicle driving safety, increasing the risk of traffic accidents, and blocking rainwater infiltration paths, leading to urban flooding and a drop in groundwater levels.
Design a permeable asphalt pavement structure, including a permeable asphalt layer, a permeable base course, an impermeable subbase, and drainage components. The permeable base course and the impermeable subbase are tightly bonded together. The permeable base course is provided with drainage chutes and drainage pipes. The anti-clogging filter is tightly bonded to the permeable base course to form an efficient drainage channel.
It enables rapid rainwater infiltration and drainage, improves road surface load-bearing capacity, reduces the risk of traffic accidents, avoids urban flooding and groundwater level decline, and extends the service life of the structure.
