Preparation method of asphalt concrete

Abstract

The invention relates to a preparation method of asphalt concrete. Concrete mixing equipment is adopted in the preparation method of the asphalt concrete. The concrete mixing equipment comprises a supporting heating device, an intermittent feeding device and a rotary mixing device. The supporting heating device is of a hollow structure. The intermittent feeding device is mounted on the upper end face of the interior of the supporting heating device. The rotary mixing device is mounted on the lower side of the interior of the supporting heating device. Through the preparation method of the asphalt concrete, the problems that when existing equipment is used for preparing the asphalt concrete, sandstone, cement and asphalt are mixed insufficiently due to continuous feeding, the mixture gets caked and hardened in a mixing device, the mixing device needs to be cleaned regularly, the processing efficiency is low, the quality of produced asphalt concrete is poor, the temperature and fluidityof asphalt in the conveying process are reduced when the existing equipment prepares the asphalt concrete, the asphalt solidifies easily and blocks a pipeline, and the processing efficiency is reducedduet to pipeline cleaning can be solved.

Description

technical field [0001] The invention relates to the field of concrete processing and manufacturing, in particular to a preparation method of asphalt concrete. Background technique [0002] Asphalt concrete, commonly known as asphalt concrete, is artificially selected with a certain gradation composition of mineral materials, crushed stone or crushed gravel, stone chips or sand, mineral powder, etc., and a certain proportion of road asphalt materials, mixed under strictly controlled conditions made mixture. [0003] At present, the existing asphalt concrete usually has the following defects when preparing asphalt concrete: 1. When the existing equipment is preparing asphalt concrete, continuous feeding leads to insufficient mixing of sand, cement and asphalt, and agglomerates in the mixing device Hardening, regular cleaning is required, the processing efficiency is low, and the quality of the asphalt concrete produced is poor; 2. When the existing equipment is preparing asph...

AI Technical Summary

Problems solved by technology

[0005] The invention can solve the problem that when the existing equipment is preparing asphalt concrete, the mixing degree of sand, cement and asphalt is insufficient due to continuous feeding, the agglomeration and hardening in the mixing device require regular cleaning, the processing efficiency is low, and the produced The quality of asphalt concrete is poor, and when the existing equipment prepares asphalt concrete, the temperature and fluidity of the asphalt transportation process are reduced, and the asphalt is easy to solidify, resulting in pipeline blockage, cleaning the pipeline and reducing processing efficiency.
