Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

Referring to fig. 1-2, the utility model discloses a water stable base layer with crack resistance function for road, which comprises a water stable base layer main body 1, wherein a water stable base layer upper layer 2 is laid above the water stable base layer main body 1, and a water stable base layer lower layer 3 is laid below the water stable base layer main body 1;

a reinforcing steel bar reinforcing layer 11 is laid on the upper surface of the water stabilization base layer main body 1, a diversion layer 12 is laid above the reinforcing steel bar reinforcing layer 11, a diversion channel 13 is formed in the surface of the diversion layer 12, and a closed conduit 14 is arranged on the side face of the diversion channel 13;
