Abstract

The invention proposes a high-strength environment-friendly water-permeable material, a preparation method thereof, and a pavement prepared by the material, which belong to the technical field of pavement paving material preparation. The pavement structure includes the following components and their weight ratios: waste rubber powder: 30-40 parts; plastic ribs: 13‑18 parts; matrix asphalt: 30‑40 parts; reinforcing fiber: 6‑10 parts; crosslinking agent: 0.1‑0.3 parts; base material: 140‑185 parts; ; Water: 20‑30 parts. The high-strength environment-friendly permeable pavement of the invention can improve the strength of the pavement and prolong the service life of the pavement.

Description

technical field [0001] The invention belongs to the technical field of preparation of pavement paving materials, in particular to a high-strength environment-friendly water-permeable material, a preparation method thereof and a pavement prepared by the material. Background technique [0002] The traditional pavement is impermeable. The purpose is to prevent groundwater from infiltrating into the pavement structure and causing damage to the pavement structure. However, this pavement structure will cause a large amount of water to accumulate in the road area in rainy weather, which will not only affect traffic operation and pedestrian travel, At the same time, rainwater runoff will be formed on the road surface, resulting in damage to the surface of the road surface; and the traditional road surface cannot absorb the noise generated during the driving of vehicles, resulting in the urban heat island effect. With the increasing awareness of the importance of sustainable developm...
