Abstract: A method for permeable pavement of dirt interception comprises laying a permeable structure layer with a toothed groove between the base layer and the transition surface of the cushion layer or directly setting the upper surface of the cushion layer as a toothed structure; in the base layer, laying at least one layer of dirt interception trough; providing a water-permeable coating or fine sand at the bottom of the sewage interception trough; the present invention traps the dirt between the base layer and the cushion layer that are most likely to cause void blocking in the base layer, close to the shallow part of the surface layer is used to remove dirt by high-pressure flushing operations.
