Construction method for non-traceless treating of slight mesh cracking disease of asphalt pavement

Abstract

The invention belongs to the technical field of asphalt road disease treatment, and particularly relates to a construction method for non-traceless treatment of a slight mesh cracking disease of an asphalt pavement. The construction method comprises the following steps of cleaning a pavement of a mesh cracking area, spraying a first layer of adhesive, spreading first layer of fine stone chips, carrying out a first rolling, spraying a second layer of adhesive, spreading second layer of fine stone chips, carrying out a second time rolling, and spraying a polyurethane waterproof coating. The construction method for non-traceless treating of the slight mesh cracking disease of the asphalt pavement provided by the invention has the advantages that the construction process is reasonable and efficient, the construction cost is low, and the repair effect is good; the construction method can effectively fill up the slight subsidence of the mesh cracking area, can prevent the crack from furtherdeveloping, prevents water from entering, and the construction method has the advantages that the color of the repairing place is close to that of the original asphalt pavement.

Description

technical field [0001] The invention belongs to the technical field of asphalt road disease treatment, and in particular relates to a construction method for non-marking treatment of slight network crack disease on asphalt pavement. Background technique [0002] The network cracks (reticular cracks) in the existing asphalt pavement are usually interlaced cracks that divide the pavement into small polygonal blocks with sharp angles that look like nets or moirés, and the size of the blocks is less than 50cm×50cm. Reticular cracks are fatigue cracks caused by repeated traffic loads. The initial form is one or several parallel longitudinal cracks. As the number of repeated loads increases, horizontal and oblique joints appear between parallel longitudinal cracks. Form polygonal, acute-angled, reticular, and crack-like crack patterns. Network cracking disease is a common quality problem that often occurs on asphalt pavement, and it will have a great impact on the quality and lif...
