Referring to fig. 1 and 2, the material of the water permeable slurry seal layer 12 is modified emulsified asphalt slurry, and has better water permeability. The medium-sized asphalt layer 13 has larger particle gaps due to larger particle sizes of asphalt particles, and has better water permeability. An asphalt mastic macadam adhesive layer 14 is also paved on the medium-grain asphalt layer 13 so as to improve the oxidation resistance and the durability of the asphalt pavement.

Referring to fig. 1 and 2, the medium asphalt layer 13 allows water to infiltrate into the road surface, and the water infiltrated into the road surface can infiltrate down through the water-permeable slurry seal layer 12, so that the drainage effect of the water on the road surface can be improved, and the anti-skid performance of the basic road surface can be improved. The cement-gravel base layer 112 and the cement-gravel base layer 112 can form a relatively compact and stable base layer 11 structure for the pavement structure, so that the possibility that the seeper water is leaked downwards has less influence on the stability of the pavement structure.
