Description

Technical Field

[0001] The utility model relates to the technical field of rubber asphalt bridge deck pavement structures, in particular to a water-permeable rubber asphalt bridge deck pavement structure. Background Art

[0002] Rubber asphalt is made by first processing the original material of waste tires into rubber powder, then combining them according to a certain coarse and fine gradation ratio, adding a variety of high polymer modifiers, and fully mixing them under high temperature conditions (above 180°C) to fully melt and swell with the base asphalt. Rubber asphalt has high temperature stability, low temperature flexibility, anti-aging, anti-fatigue, and water damage resistance. It is an ideal environmentally friendly pavement material and is mainly used in the stress absorption layer and surface layer of road structures.

[0003] Currently, rubber asphalt is widely used. When used for bridge deck paving, the current rubber asphalt is directly paved on the bridge deck, which has poor water permeability and is likely to cause the bridge deck to be damp for a long time, affecting driving safety. In addition, the existing permeable rubber asphalt bridge deck paving structure has poor anti-leakage performance of the bridge body itself. If the bridge body itself is in a humid environment for a long time or is penetrated by rainwater, it is easy to affect the life of the bridge body, thereby seriously affecting driving safety. Therefore, the existing permeable rubber asphalt bridge deck paving structure has the disadvantages of poor hydrophobicity and permeability and poor anti-seepage effect. Utility Model Content
