Crushed stone seal paver and use method thereof

Abstract

The invention discloses a chip sealing vehicle and a using method thereof.The chip sealing vehicle comprises a vehicle body, a transverse rib preparing device, a longitudinal rib preparing device, a high-temperature fixing device, an asphalt tank and a material collecting tank, and the transverse rib preparing device, the longitudinal rib preparing device, the high-temperature fixing device, the asphalt tank and the material collecting tank are all fixedly installed on the vehicle body; the longitudinal rib preparing device is located in the transverse rib preparing device, and the asphalt tank and the material collecting tank are located on the rear portion of the vehicle body. According to the method, it is guaranteed that transverse ribs and longitudinal ribs of the prepared geogrid are stacked in a staggered mode, the geometric size of geogrid meshes needed by a road is calculated according to the interlayer shearing performance of the road surface and the traffic load grade of the road, the geogrids meeting different asphalt road surfaces are automatically manufactured and paved, the integrated operation from manufacturing to paving of the geogrids is completed, and the production efficiency is improved. The problem that the stability between the gravel sealing layer and the base layer is poor is solved, and meanwhile the problems that geogrids need to be prefabricated in advance, and time and labor are consumed in manual paving are solved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a gravel sealing vehicle and a method for using the same. Background technique [0002] Due to its simple construction process, low cost, wide application range, and less environmental pollution, the crushed stone seal layer is suitable for preventive maintenance and repair of roads of different grades, and is very popular in road construction and reconstruction. [0003] However, the crushed stone seal layer has the disadvantages of loose particles and poor adhesion to the pavement base layer. Adding geogrid between the base layer and the surface layer can effectively improve the shear strength and rutting resistance of the pavement. However, the traditional geotechnical The grid needs to be prefabricated in advance, and requires a lot of manpower and material resources for production and paving. It cannot be paved immediately, and in the paving process, it cannot be p...

Problems solved by technology

[0003] However, the crushed stone seal layer has the disadvantages of loose particles and poor adhesion to the pavement base layer. Adding geogrid between the base layer and the surface layer can effectively improve the shear strength and rutting resistance of the pavement. However, the traditional geotechnical The grid needs to be prefabricated in advance, and requires a lot of manpower and material resources for production and paving. It cannot be paved immediately, and it cannot be paved simultaneously with the asphalt pavement during the paving process, which slows down the construction progress.

When selecting the mesh of traditional geogrid, it is generally selected based on construction experience, which may lead to poor interlayer stability of the pavement after laying, and poor anti-rutting ability.
