Abstract

The invention discloses a cement pavement EAP fine anti-sliding wear layer and a construction method thereof. The cement pavement EAP fine anti-sliding wear layer comprises, by weight, 100 parts of afine aggregate, 10-25 parts of an epoxy asphalt binder and 5-10 parts of a stabilizer. The construction method comprises: a, closing a construction section, grinding an old cement pavement, repairinglocal damage and cleaning the pavement, b, simultaneously spraying the fine aggregate and the epoxy asphalt binder on the cement pavement by a synchronous gravel sealer to obtain an epoxy asphalt anti-sliding wear thin layer and rolling the epoxy asphalt anti-sliding wear thin layer through a pneumatic-tired roller 1-2 times, and c, spraying a stabilizer onto the epoxy asphalt anti-sliding wear then layer through an asphalt spreader after the epoxy asphalt anti-sliding wear thin layer is cured, carrying out maintenance molding and quality inspection and handing over and using the qualified product. The cement pavement EAP fine anti-sliding wear layer has the advantages of water prevention, sliding resistance, corrosion resistance and wear resistance, fast repairs the surface structure of the old cement concrete pavement and improves the anti-sliding ability of the pavement and the appearance of the pavement.

Description

technical field [0001] The invention relates to the related fields of maintenance and repair of cement concrete pavement, in particular to an EAP fine anti-skid wear layer of cement pavement and a construction method. Background technique [0002] With the continuous development of urban construction in our country, urban roads, as an important part of urban construction, play a pivotal role in the process of urban construction. The scale and mileage of road construction are increasing exponentially every year. For a long period of time after the founding of New China, the pavement structure in urban road construction is mainly cement concrete pavement. Cement concrete pavement has the advantages of high strength, high rigidity, good durability, low cost and easy daily maintenance, etc., but the shortcomings of cement concrete pavement are also very obvious, especially the macroscopic structure and microscopic texture of cement concrete pavement. The problem of anti-slip on...
