Embodiment Construction

[0013] Referring to accompanying drawing, the technical scheme step that the present invention adopts is as follows:

[0014] (1), preparation of asphalt mixture; (2), transportation of asphalt mixture; (3), ferrying of asphalt mixture; (4), paving of asphalt mixture; (5), pressing of asphalt mixture Reality.

[0015] After the mixing device prepares the material and asphalt into a qualified asphalt mixture, it is loaded on a dump truck, and the dump truck unloads the asphalt mixture into the hopper of the asphalt mixture ferry vehicle. The basic working principle of the ferry vehicle is: A hopper, a feeding scraper system, a silo and a secondary discharging scraper system are arranged on the self-propelled chassis. The dump truck pours the asphalt mixture into the hopper, and the asphalt mixture is poured by the feeding scraper system. Input into the silo, the asphalt mixture is fully stirred in the silo of the asphalt mixture ferry vehicle, and reaches a uniform level, the ...

Abstract

The present invention discloses a mechanized construction process of asphalt mixed material pavement layer, and it includes the following steps: 1. preparation of asphalt mixed material; 2. conveyance of said asphalt mixed material; 3. ferrying asphalt mixed material; 4. spreading asphalt mixed material; and 5 compacting the asphalt mixed material. Said invention can raise the quality of pavement layer, and can prolong service life of asphalt pavement layer by about 40%.

Description

technical field [0001] The invention relates to a mechanized construction technology of road surface, in particular to a mechanized construction technology of asphalt mixture road surface. Background technique [0002] In the construction of road pavement, the paving process of traditional asphalt pavement is to mix the asphalt mixture in the asphalt mixing equipment, and then use several dump trucks to transport the asphalt mixture to the construction site, and then transport the asphalt mixture from the dump The truck is directly unloaded into the hopper of the paver, and the dump truck and the paver basically move forward synchronously. The paver paves along the road surface, and the road roller compacts the road surface. Such a paving process produces the following problems: (1) The temperature and material segregation will occur during the transportation of asphalt mixture from the mixing equipment to the paver hopper, which will seriously affect the quality of the road...
