Embodiment 1

[0030] A factory-prefabricated water-sealed anti-skid and anti-crack pavement sticker includes: a release paper layer, an anti-crack cloth layer, a lower binder layer, an aggregate layer, an upper binder layer and a surface protection layer; the upper binder layer and The lower binder layer covers the aggregate layer.

[0031] in,

[0032] The release paper layer is made of double-sided release paper.

[0033] The anti-crack cloth layer is made of polyester fiber anti-crack cloth.

[0034] Both the upper binder layer and the lower binder layer are paved with emulsified high-viscosity modified asphalt. The emulsified high-viscosity modified asphalt is compounded and emulsified by 50 parts of base asphalt, 7 parts of SBS, 5 parts of SBR, 2 parts of SEBS, 3 parts of epoxy resin, 2 parts of emulsifier, and 20 parts of water.

[0035] Compared with the existing modified emulsified asphalt, the emulsified high-viscosity modified asphalt used in this example has significant advant...

Embodiment 2

[0054] A factory-prefabricated water-sealed anti-skid and anti-crack pavement sticker includes: a release paper layer, an anti-crack cloth layer, a lower binder layer, an aggregate layer, an upper binder layer and a surface protection layer; the upper binder layer and The lower binder layer covers the aggregate layer.

[0055] in,

[0056] The release paper layer is made of single-sided release paper.

[0057] The anti-crack cloth layer is made of polyester fiberglass anti-crack cloth.

[0058] Both the upper binder course and the lower binder course are laid with commercially available modified asphalt.

[0059] The aggregate layer is formed by laying aggregates. In this embodiment, the aggregates are 98 parts of diabase rock and 2 parts of high elastic rubber particles. Form a multi-texture aggregate layer, preferably a multi-texture single-size aggregate layer (particle size 2.36~4.75mm), which provides good wear resistance and skid resistance, low driving noise, and ens...

Embodiment 3

[0074] A factory-prefabricated water-sealed anti-skid and anti-crack pavement sticker includes: a release paper layer, an anti-crack cloth layer, a lower binder layer, an aggregate layer, an upper binder layer and a surface protection layer; the upper binder layer and The lower binder layer wraps the aggregate layer.

[0075] in,

[0076] The release paper layer is made of single-sided release paper.

[0077] The anti-crack cloth layer is laid by carbon fiber anti-crack cloth.

[0078] Both the upper binder layer and the lower binder layer are laid by commercially available polyurethane.

[0079] The aggregate layer is made of aggregates. In this embodiment, the aggregates are 60 parts of basalt rock and 40 parts of diorite rock (particle size 2-3mm).

[0080] The surface protection layer is sprayed with a thermosetting polymer binder; in this embodiment, the thermosetting polymer binder is compounded from 7 parts of styrene-acrylic emulsion and 3 parts of chloroprene latex...

Abstract

The invention discloses a water-sealing anti-slip and anti-crack pavement paste made in a factory, a preparation method and a construction method thereof, belonging to the field of highway maintenance. The invention comprises an isolation paper layer, an anti-crack cloth layer, a lower binder layer, an aggregate layer, an upper binder layer and a surface protection layer. The surface protective layer is sprayed with thermosetting polymer binder. The pavement sticker of the invention completely wraps the aggregate and forms a continuous adhesive material layer to ensure that the water permeability coefficient is 0; Multi-texture surface structure and surface protective film ensure the anti-slip coefficient BPN >= 55 and the driving noise is low; The longitudinal and transverse fracture strength is high, and the reflection crack is delayed. The pavement paste of the invention is directly applied to the tortoise-shaped cracks of the local pavement network which needs to be repaired or thewhole pavement is corrected and pre-cured when the pavement is used after the pavement is brushed and the binder is coated. The pavement paste of the invention is convenient to use, can quickly openthe traffic, has long service life, high performance-price ratio, is green, low-carbon, energy-saving and environment-friendly, and has remarkable social and economic benefits.

Description

technical field [0001] The invention relates to the technical field of road maintenance, in particular to a factory-prefabricated water-sealed anti-skid and anti-crack pavement sticker and its preparation and construction methods. Background technique [0002] Preventive maintenance is an important part of road maintenance. Two to three years after the road is open to traffic, the overall structural strength is sufficient, and the surface layer has problems such as binder aging, aggregate shedding, and insufficient skid resistance, especially those caused by fatigue and reflective cracks. The decrease of structural strength and the increase of water seepage accelerate the expansion of minor diseases to moderate and severe diseases. Therefore, appropriate preventive maintenance measures should be taken in time to realize the maintenance of pavement functions, the recovery of pavement functions, the extension of pavement service life, and the elimination of traffic accidents. ...
