Water drainage anti-cracking type cold-recycling pavement structure
The invention discloses a water drainage anti-cracking type cold-recycling pavement structure, belonging to the technical field of road surface pavement. The pavement structure comprises a cold-recycling layer and is characterized in that a permeable stress absorbing layer is arranged at the lower part of the cold-recycling layer, and the permeable stress absorbing layer adopts high-viscosity rubber asphalts as a cementing material. Compared with the prior art, the pavement structure is provided with a water drainage anti-cracking layer at the bottom of the cold-recycling layer for draining moisture entering the pavement structure horizontally, up-down water damage of the pavement is avoided, a bottom-top reflection crack of the pavement structure is avoided, the damage to the pavement structure can be effectively avoided, and the anti-cracking type cold-recycling water drainage pavement structure has high promotion and application values.
