Abstract

The invention discloses a factory-prefabricated self-adhesive pavement sticker, a preparation method and a construction method, belonging to the technical field of highway maintenance. The invention comprises an isolation paper layer, a self-adhesive adhesive layer, an anti-cracking cloth layer, a lower binder layer, an aggregate layer and an upper binder layer. 15 DEG C pull-out test>= 0. 5MPa;The binder completely covers the aggregate and forms a continuous bonding material layer to ensure that the water permeability coefficient is 0; Multi-texture surface structure and surface protectivefilm 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 sticker of the invention is directly applied to the tortoise-shaped cracks of the local pavement network which needs to be repaired or the whole pavement is corrected and pre-cured, is convenient to use, can quickly open the traffic, has long service life, 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 self-adhesive 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. Potential safety hazards...
