Problems solved by technology

[0002] The desert area is dry and lacks water, and the construction of cement pavement requires a lot of water resources, so it is not suitable to use cement pavement
For asphalt pavement, the temperature is low in the morning and evening in summer, and the temperature is low in winter for a long time, so it is impossible to construct hot-mix asphalt pavement; constructing emulsified asphalt or foamed asphalt cold-mix asphalt pavement requires a lot of water, and it cannot be used when it freezes in winter construction

Embodiment 1

[0039] The desert highway prefabricated asphalt pavement of the present invention is implemented on a certain expressway.

[0040] like figure 1 As shown, the prefabricated asphalt pavement of the desert road described in this embodiment includes a combination layer of asphalt pavement prefabricated blocks, a gravel base 4, and an aeolian sand roadbed 5, wherein the asphalt pavement prefabricated block combination layer, the gravel base 4. The aeolian sand subgrade 5 is laid in sequence from top to bottom according to the layered superimposed structure. The asphalt pavement prefabricated block composite layer is assembled and paved by a plurality of asphalt pavement prefabricated blocks, and the plane dimensions of each asphalt pavement prefabricated block are: 5 m in length and 1 m in width. The thickness of the crushed stone base 4 is 15cm, and a plurality of reinforcing units 3 are laid on its upper surface, which can be geogrids, geotextiles or glass fiber cloths. In this...

Abstract

The invention discloses an assembly asphalt pavement for a desert highway and a construction method of the assembly asphalt pavement. The asphalt pavement comprises an aeolian sand subgrade, wherein a macadam base and an asphalt pavement precast block combination layer are sequentially laid on the upper surface of the aeolian sand subgrade from bottom to top according to a laminated structure, and the asphalt pavement precast block combination layer is formed by assembling and paving a plurality of asphalt pavement precast blocks; a plurality of reinforcing units are laid on the upper surface of the macadam base, correspond to joints of every two asphalt pavement precast blocks one to one, and are used for reinforcing the joints of the asphalt pavement precast blocks, and the macadam base and the asphalt pavement precast block combination layer are fixed by bonding; each asphalt pavement precast block sequentially comprises an asphalt surface course and a base plate from top to bottom according to a laminated structure, and each asphalt surface course and the corresponding base plate are fixed into a whole by bonding. The assembly asphalt pavement provided by the invention has the advantages of water-saving construction, prolonged construction season, rapid construction, rapid maintenance and the like.

Description

technical field [0001] The invention relates to the technical field of desert highways, in particular to a desert highway assembled asphalt pavement and a construction method thereof. Background technique [0002] The desert areas are dry and water-deficient, and the construction of cement pavement requires a lot of water resources, so cement pavement should not be used. For asphalt pavement, the temperature is low in the morning and evening in summer, and the temperature is low in winter for a long time, so hot mix asphalt pavement cannot be constructed; construction of emulsified asphalt or foam asphalt cold mix asphalt pavement requires a lot of water, and it is impossible to construct pavement with icing in winter. construction. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a desert highway prefabricated asphalt pavement and a construction method thereof, which realizes water-saving...
