Problems solved by technology

However, the existing technology of synchronous fiber-reinforced gravel seal layer needs to rely on the natural driving action for compaction. Due to the uneven distribution of the driving track in the lateral direction of the road, its overall consistency cannot be guaranteed, and the effective structural reinforcement cannot be achieved. The durability of the project also needs to be improved; in addition, because there are a lot of negative textures on the surface after construction, this leads to loud noise inside and outside the vehicle driving on it, and poor driving comfort

Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] like figure 1 Shown is a pavement structure that quickly restores the function of pavement and bridge deck, including double-layer fiber reinforced crushed stone seal and ultra-thin anti-skid wear layer from bottom to top.

[0026] The double-layer fiber-reinforced gravel sealing layer includes a lower binder layer, a chopped fiber layer, an upper binder layer and a single-size stone chip layer from bottom to top. Both the lower adhesive layer and the upper adhesive layer are formed by sprinkling adhesive, and the adhesive is rubber asphalt, epoxy resin or epoxy asphalt, and the sprinkling of the lower adhesive layer The amount is 0.2~0.6kg / m 2 , the spreading amount of the upper adhesive layer is 0.2~0.4kg / m 2 . The chopped fiber layer is laid by chopped fibers, and the single-size stone chips layer is formed by spreading single-size stone chips, and the si...

Abstract

The invention discloses a paving structure and a paving method for quickly recovering functions of a pavement and a bridge floor. The paving structure comprises a double-layer fiber-added macadam seal layer and an ultrathin antiskid wearing layer from the bottom up, wherein the double-layer fiber-added macadam seal layer comprises a lower binder layer, a chopped fiber layer and an upper binder layer from the bottom up. According to the paving structure and the paving method for quickly recovering the functions of the pavement and the bridge floor, compared with the prior art, on the basis that the original paving is made full use of, gap graded aggregate is adopted to achieve water proofing of the pavement, prevent water from damaging the pavement, and exert the functions of water shutoff and drainage simultaneously; and the paving structure is high in construction efficiency, and can reduce the interference of the traditional construction manner to traffic.

Description

technical field [0001] The invention relates to a pavement structure and a pavement method for quickly restoring the functions of road surfaces and bridge decks, which are suitable for the maintenance and rapid restoration of pavement pavement and bridge deck pavements of existing roads, and belong to the road surface maintenance technology. Background technique [0002] With the continuous construction and use of expressways and long-span steel box girder bridges across rivers and seas in my country, the maintenance and repair technology of high-grade asphalt pavement and steel bridge deck pavement has become one of the important contents of current research. [0003] The main diseases of asphalt pavement are cracks, potholes, ruts, etc., and the traffic on expressways and bridge decks has the characteristics of large traffic volume and fast speed. In order to ensure the high-speed, safe and comfortable passage of vehicles, disease treatment must be carried out in a timely a...
