Abstract

The invention discloses a wear-resistant embedded type anti-skid layer of a new cement concrete pavement and a construction method, and relates to the technical field of highway engineering. The wear-resistant anti-skid layer comprises a wear-resistant material embedded in the surface of the new cement concrete pavement; when being used for tunnel pavements, the wear-resistant material includes high wear-resistant aggregates, pigments and a retroreflection material, and when being applied to other parts, the wear-resistant material only includes the high wear-resistant aggregates; and the highwear-resistant aggregates are natural or artificial stones each with a polishing value of not less than 45PSV. The construction method comprises the following innovated contents: base treatment and necessary preparation work; concrete layer concrete proportion design, workability requirement, a construction method for and process control over a surface mortar layer; a construction and control method for the wear-resistant material embedded anti-skid functional layer, a uniform spreading method for the wear-resistant material, an embedding and endurance method for the wear-resistant material,a skid resistance and flatness improvement method for he wear-resistant layer, and the like; anti-slip layer curing at a plastic stage, structure treatment and the like. The anti-skid layer can save scarce natural sand resources, makes full use of recycled aggregates, and realizes changing wastes into treasures.

Description

technical field [0001] The invention relates to the technical field of highway engineering, in particular to a newly built cement concrete pavement wear-resistant material embedded anti-skid layer and a construction method. Background technique [0002] The current situation of poor anti-skid performance of high-grade cement pavement in my country is mainly manifested in the erosion of anti-skid microstructure and groove macrostructure in about 3-4 years. Hidden danger. Especially under the action of rainwater, the skid resistance attenuates significantly. In addition, it also faces the test of super-heavy traffic. Contents of the invention [0003] The purpose of the present invention is to provide a newly built cement concrete pavement wear-resistant material embedded anti-skid layer and construction method to solve the problem of existing cement concrete pavement anti-skid performance. The anti-skid functional layer is newly paved cement concrete pavement The surface l...
