S1, paving a reinforcing and stabilizing frame (6) on the surface of the latticed frame (5), installing a plurality of vertical fixing rods (16) in the reinforcing and stabilizing frame (6), enabling the distance between two transversely arranged vertical fixing rods (16) to be 5-15cm, enabling the distance between two vertically arranged vertical fixing rods (16) to be 8-12cm, stably connecting two adjacent vertical fixing rods (16) through connecting shafts (17), and stably connecting the two connecting shafts (17) through reinforcing columns (18) to form a supporting surface in the latticed frame (5);

s2, filling elastic particle bodies (19) in the latticed frame (5) to enable the elastic particle bodies (19) to fill the whole latticed frame (5);

laying an upper base layer (7) on the surface of the reinforced stable frame (6), spraying water mist on the surface of the upper base layer (7) to keep the upper base layer (7) in a wet state, and covering the surface of the upper base layer with a heat-insulating layer after finishing laying until the upper base layer (7) is restored to a dry state;

and step six, paving a pavement layer (8) on the surface of the upper base layer (7), wherein the pavement layer (8) is a mixture of sedimentary rocks with the grain size of 0.5mm and asphalt with the grain size of 2 mm.

7.
