A kind of asphalt concrete highway construction method

Abstract

The invention relates to the field of road construction, in particular to a construction method for asphalt concrete roads, which uses an asphalt concrete road construction device, the asphalt concrete road construction device includes a machine body and a pressure plate, both sides of the machine body are fixedly installed with Supporting frame, there is an arc-shaped raw material chute in the body, the top of the raw material chute runs through the body, and a number of rollers are correspondingly arranged in the body, and a conveyor belt is set between the rollers. The conveyor belt covers the raw material trough, and the conveyor belt runs through the body. At the bottom of the machine body, a number of reinforcing rods are symmetrically fixed and fixed on the conveyor belt, and scrapers are fixedly installed on the reinforcing rods. The bottom of the machine body and one side of the raw material tank are provided with a pressure groove, and the pressure plate is inserted in the pressure groove. Inside, a No. 1 air cylinder is fixedly installed in the pressure tank. The invention can pressurize the cast asphalt concrete, so that the asphalt concrete can efficiently penetrate into the gravel, and is suitable for popularization.

Description

technical field [0001] The invention relates to the field of road construction, in particular to an asphalt concrete road construction method. Background technique [0002] Road is an important infrastructure in modern society. There are many types of roads, which are generally made of concrete. However, conventional concrete roads are prone to cracking after long-term use, which greatly limits the service life of roads. [0003] Therefore, existing roads are often cast with asphalt concrete, which can greatly improve the strength of the road surface, avoid cracking, and improve the service life of the road. However, when casting asphalt concrete, it is usually necessary to Lay a layer of crushed stones, and then lay asphalt concrete on the crushed stones.

[0002] Road is an important infrastructure in modern society. There are many types of roads, which are generally made of concrete. However, conventional concrete roads are prone to cracking after long-term use, which greatly limits the service life of roads.

[0003] Therefore, existing roads are often cast with asphalt concrete, which can greatly improve the strength of the road surface, avoid cracking, and improve the service life of the road. However, when casting asphalt concrete, it is usually necessary to Lay a layer of crushed stones, and then lay asphalt concrete on the crushed stones. Most of the existing construction methods are manually pouring asphalt concrete on the crushed stones, and then smoothing with troweling equipment. It will prevent the asphalt concrete from completely penetrating into the gravel, reducing the strength of the asphalt concrete. At the same time, the manual laying is inefficient and increases the construction period of the asphalt concrete road.
