Asphalt laying device and method for highway construction

Abstract

The invention discloses an asphalt laying device and method for highway construction. The asphalt laying device comprises a base and walking wheels arranged on the left side and the right side of the base and used for walking, a stirring barrel used for storing asphalt materials is arranged at the upper end of the base, and a stirring assembly used for stirring asphalt is arranged in the stirring barrel. The right end of the base is provided with a tiling assembly used for evenly tiling asphalt on the road surface, and a conveying assembly used for conveying the asphalt is arranged between the tiling assembly and the stirring barrel. The asphalt mixing device is designed for overcoming the defects of an existing device, asphalt can be circularly stirred, fed asphalt can be divided into multiple strands according to the paving width, the uniform paving is facilitated; and in addition, adjustment can be carried out according to road surfaces with different widths, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of road equipment, in particular to an asphalt paving device and method for road construction. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is liquid, semi-solid or solid. It is a waterproof, moisture-proof and anti-corrosion organic gelling material. Used in coatings, plastics, rubber and other industries, as well as paving roads, etc. Asphalt is solid at room temperature, so it needs to be heated to melt the solid asphalt when used. The heating temperature is generally around 120°C. The asphalt heating in the prior art is generally heated by a boiler, which is not conducive to carrying out operations and consumes a lot of manpower. Material resources and time lead to low production efficiency. The existing patent announcement number of CN108824142B discloses a kind of asphalt laying devi...

Problems solved by technology

Asphalt is solid at room temperature, so it needs to be heated to melt the solid asphalt when used. The heating temperature is generally around 120°C. The asphalt heating in the prior art is generally heated by a boiler, which is not conducive to carrying out operations and consumes a lot of manpower. Material resources and time lead to low production efficiency. The existing patent announcement number of CN108824142B discloses a kind of asphalt laying device with stirring function for road construction. It is not easy to spread the asphalt evenly when laying, and it needs to be assisted by vibration, but this vibration is not conducive to improving the service life of the device
