Road construction method

Abstract

The invention discloses a road construction method. The road construction method comprises steps of flattening an area to be constructed to form a horizontal roadbed; laying a cushion layer on the roadbed; laying an asphalt layer on the cushion layer and compacting the asphalt layer while the asphalt layer is hot; laying one layer of emulsified asphalt in a molten state; laying an asphalt mixturepavement layer on the emulsified asphalt and compacting the asphalt mixture pavement layer while the asphalt mixture pavement layer is hot; after the roadbed is formed, laying measuring slide rails onthe two sides, wherein infrared laser transmitters and receiving seats are correspondingly and slidingly connected to the two measuring slide rails; during the construction of each layer of structure, calculating a virtual elevation H of a central point of the layer of the structure according to designed double-slope value i% and width L of each layer of structure; and obtaining a lifting amountor a digging amount through calculation. Through the arrangement, the control of each layer is simple and clear, the labor cost can the labor intensity can be reduced, and meanwhile, the working efficiency is enhanced, the situation of mechanical idling of the labour force is reduced, and moreover, the construction quality can also be preferably guaranteed, and the flatness and the construction quality of a road are improved.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a road construction method. Background technique [0002] Road construction generally includes leveling the site to form a roadbed, laying a cushion, laying asphalt or concrete on the cushion to form the main structure of the road, and then laying the surface layer. If it is asphalt, it needs to be compacted with a road roller while it is hot, and the road can be completed. construction process. For different road grades, there are corresponding changes and requirements. Similarly, corresponding adjustments will be made in the construction process or process. Regardless of the grade of road, the flatness of the road surface during construction is the same. An important indicator of the performance of the cheap road surface, it directly affects the driving quality of the vehicle on the road surface and the full play of the basic functions of the road. [0003] Therefor...

Problems solved by technology

[0004] In the current road construction process, the control of the flatness is mainly in the form of machinery supplemented by manual work. Before construction, the existing surveyors measure and set out each section and each layer in the construction, so that the machinery can carry out the construction, and the construction process requires The surveyors recheck the measurement data many times for guidance, such as coordinates, elevation, etc., and the technical requirements for mechanical operators are also high. The whole process requires continuous verification and measurement, and the cooperation between machinery and labor can complete the construction of each layer of structure. Elevation control, if the road is long and segmented, parallel flow operation, it is easy to cause mechanical and artificial slowdown
