Embodiment Construction

[0045] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0046] A road paving method such as figure 1 As shown, the road includes a subgrade 1 , a cushion course 2 , a subbase course 3 , an upper course course 4 and a surface course 5 in sequence.

[0047] The roadbed 1 is excavated at a certain distance to form grooves 11 , and the cushion layer 2 is gravel laid on the surface of the roadbed 1 and the grooves 11 .

[0048] refer to figure 1 and figure 2 , the base layer 3 includes skeletons 31 arranged along the pad 2 and connectors 33 laterally connecting adjacent skeletons 31, the connectors 33 include a rod 331 and a spherical end 332 whose diameter is larger than that of the rod 331, and the skeleton 31 is provided with There is an embedding groove 311 for the spherical end 332 to engage with and a through hole 312 for the rod to pass through.

[0049] refer to figure 1 and image 3 The two ends of the ...

Abstract

The invention relates to a road pavement method. A roadbed, an underlayer, a subbase layer, an upper base layer and a face layer are sequentially involved. The method comprises the construction stepsof roadbed finishing, underlayer paving, template adjustment, preliminary grinding, preliminary framework installation, material supplementing, secondary paving, secondary grinding and maintenance. The road pavement method has the advantages that the construction efficiency is high, the toughness, structural strength and the mutual adhesion effect between every two layers are good, the safety of apipe network is guaranteed, and the structural strength of a road itself is also effectively improved.

Description

technical field [0001] The invention relates to the field of municipal engineering, in particular to a road paving method. Background technique [0002] In the process of road construction, in order to obtain a flat road surface structure, it is usually necessary to carry out rolling treatment on the paved pavement materials, and then it can be opened to traffic after being compacted and leveled. At the same time, in order to make the road surface have sufficient strength and compressive capacity, when laying the road surface, most of them adopt a multi-layer paving structure. [0003] For example, the Chinese patent whose publication number is CN103993534 discloses a "road construction method", which adopts spreading rubber asphalt on the surface of the asphalt pavement to form a rubber asphalt layer, and lays gravel on the rubber asphalt layer to form a gravel layer. This is achieved by laying an emulsified asphalt layer on top of the gravel layer. Although the pavement ...
