A method for laying integral pavements

Abstract

The invention relates to the field of water stability and asphalt pavement construction of all highway engineering, and particularly discloses an overall pavement laying method. The overall pavement laying method comprises the steps that firstly water stability construction is performed, after a water-stable layer is paved, liquid asphalt is uniformly sprayed to permeate into the water-stable layer, and then compaction construction is performed; and secondly, asphalt is paved on the already compacted road surface in a layer mode, and each layer of the asphalt is paved with a paver with a heating function to control the heating temperature. The overall pavement laying method reduces the influence of vehicle load on the road surface, improves the process environment, reduces the conditions for disease generation, improves the quality and prolongs the life of the road surface, and reduces the construction cost.

Description

technical field [0001] The invention relates to the fields of all highway engineering water stability and asphalt pavement construction, in particular to an integral pavement laying method. Background technique [0002] Asphalt pavement is an application form of pavement structure at present, and it is the main application form of high-grade pavement and mainstream pavement structure. The design and construction of the pavement increase layer by layer according to the gradation gradient. Generally, there is a bonding layer (emulsified asphalt or hot asphalt spreading layer) between the layers, and the multi-layer pavement structure is combined into a whole by means of interlayer bonding. pavement structure. The pavement paved by the current paving method is prone to strong interlayer shear stress. If the shear stress is too large, the asphalt mixture will be rubbed. Long-term rubbing will cause the rheology of the mixture, so that the pavement is greatly affected by the veh...

Problems solved by technology

The pavement paved by the current paving method is prone to strong interlayer shear stress. If the shear stress is too large, the asphalt mixture will be rubbed. Long-term rubbing will cause the rheology of the mixture, so that the pavement is greatly affected by the vehicle load. The pavement is easy to be damaged, for example, it is easy to cause a single layer of the pavement to fall off, ruts, chicken claws, etc.
