Melting, nourishing and protecting method for asphalt concrete road

Abstract

At the present stage of China, most of the roads are asphalt concrete roads, a small part of the asphalt concrete roads are damaged, an existing maintenance method is a patching method, and the method has the defects of time waste and labor waste, namely contour cutting is carried out on a damaged area by using a cutting machine, then the damaged road surface is excavated and cleaned, and then asphalt concrete is used for filling and flattening; the invention discloses a fusion compensation method. 2, foreign matter cleaning is conducted on the pavement damage area of the asphalt concrete road, and dust in the pavement damage area is cleaned through a brush and an air blower; step 2, heating the damaged area of the pavement by adopting asphalt concrete pavement melting equipment, so that the pavement is heated to the asphalt concrete paving temperature; 2, asphalt concrete is supplemented and paved in the pavement damage area; compared with an existing patching method, the method has the advantages that the damaged pavement does not need to be cut and cleaned, the process is simple, the operation time is shorter, and the efficiency is high.

Description

[0001] Technical Field The present invention relates to a method for repairing and maintaining an asphalt concrete road.

[0002] Background technology At present, my country has more than 5 million kilometers of roads, most of which are asphalt concrete roads. For small parts of damaged asphalt concrete roads, the current maintenance method is the digging and patching method, which has the disadvantages of being time-consuming and labor-intensive. That is, the damaged area is contour cut with a cutting machine, and then the damaged road surface is dug out and cleaned, and then filled and flattened with asphalt concrete.

[0003] SUMMARY OF THE INVENTION The object of the present invention is to provide a method for the maintenance of asphalt concrete roads.

[0004] The asphalt concrete road fusion and repair method has the following steps:

[0005] The first step is to clean foreign objects from the damaged area of ​​the asphalt concrete road surface and use a brush and blower to clean the dust from the damaged area of ​​the road surface.

[0006] The second step is to use asphalt concrete pavement melting equipment to heat the damaged area of ​​the pavement at a constant temperature so that the pavement temperature rises to the asphalt concrete paving temperature.

[0007] Step 3: Pave the damaged area of ​​the road with asphalt concrete.

[0008] Step 4: Use roller equipment to flatten the road surface.

[0009] Advantages of the present invention: Compared with the existing excavation and patching method, the present invention has the advantages of no need to clean the damaged road surface, simple process, shorter operation time and high efficiency. DETAILED DESCRIPTION

[0011] The implementation of the present invention is described by taking the maintenance and repair of a circular road pit with a diameter of 20 cm.

[0012] Construction equipment preparation

[0013] Asphalt concrete pavement melting equipment is manufactured by customizing an electric heating plate with a side length of 50 cm as a heat source. To prevent heat dissipation, a heat collecting cover is set outside the heating plate, and the heating plate is installed inside the heat collecting cover. A constant temperature control method is adopted inside the heating plate, and the temperature is controlled by a temperature control instrument. Different temperatures are set according to different types of asphalt.

[0014] The power supply of the heating plate ground melting equipment can be taken from the battery of a new energy vehicle, or it can be powered by a 20KW diesel generator set.

[0015] Other conventional existing equipment required include a small road roller and an asphalt concrete mixer truck.

[0016] With construction operations:

[0017] The first step is to use cleaning tools to clean the dust and dirt in the potholes and surrounding areas.

[0018] The second step is to cover the pothole with the asphalt concrete pavement melting equipment, connect the power supply, and radiate heating to the ground at a constant temperature of 130 degrees Celsius.

[0019] The third step is to remove the asphalt concrete pavement melting equipment when the pavement temperature rises to the temperature required by the process.

[0020] The fourth step is to fill and pave the damaged areas with asphalt concrete.

[0021] The fifth step is to use a small roller to flatten the road surface.
