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 assembled asphalt pavement of the desert road of the present invention has been implemented on a certain expressway.

[0040] like figure 1 As shown, the assembled asphalt pavement of the desert road described in this embodiment includes an asphalt pavement prefabricated block composite layer, a crushed stone base 4, and aeolian sand subgrade 5, wherein the asphalt pavement prefabricated block composite layer, crushed stone base 4. The aeolian sand subgrade 5 is laid sequentially from top to bottom according to the layered superposition structure. The composite layer of prefabricated asphalt pavement blocks is formed by assembling and paving a plurality of prefabricated asphalt pavement blocks, and the planar dimensions of each prefabricated asphalt pavement block are: length 5m, width 1m. The thickness of the crushed stone base 4 is 15cm, and a plurality of reinforcement units 3 are laid on its upper surface, which can be geogrid, geotextile or glass fiber cloth, ...

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 roads, in particular to an assembled asphalt pavement of desert roads and a construction method thereof. Background technique [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. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a desert highway assembled asphalt pavement and its construction method, which realizes water-saving construction, prolo...
