2.1 Selecting materials to meet requirements

Generally speaking, the selected mixture must meet the relevant aspects of the standards, such as high temperature stability, low temperature crack resistance, wheelbase performance, and long service life of the cable asphalt manufacturer. D. It's a great mixture. When selecting asphalt mixture fillers, it is also necessary to ensure that the selected materials meet the requirements for functionality. Generally, hard stones with strong wear resistance and good mosaic properties are selected, and asphalt materials can be effectively combined with the materials. Assuming the filler is acidic, an appropriate amount of preservative or lime powder should be added to ensure the anti drop properties of the mixture before adjustment.

2.2 Ensure strength and maintain stability

The roadbed is the most basic pavement structure and the primary part of the load-bearing pavement. Therefore, the strength and stability of the road surface have a significant impact on the overall strength and stability of the road structure, which requires construction personnel to inspect both ends. The process of roadbed filling should be strictly controlled, and the filling materials should be selected according to the construction standards. Unqualified materials should obstruct their use. The new journey will present issues such as uneven rolling, partial sealing or inadequate sealing at both ends of the journey, which will have a significant impact on the functionality of the road surface and often lead to varying degrees of cracks. This requires builders to conduct inspections in many aspects to ensure that all policies are in line with their interests.

2.3 Spread voltage, accelerated absorption by cable asphalt manufacturers

After carefully studying the causes of reflection cracks, we need to lay low elastic modulus materials between the bottom layer and the surface, such as rubber asphalt, sand, and crushed stone in the middle layer. These intermediate layers can effectively absorb the stress generated by the bottom reflection, greatly reducing the adverse effects of crack formation and maintaining the usefulness of the journey function.

2.4 Adjust the bottom layer and add thickness

Humidity and temperature are important factors affecting the functionality of the underlying material, which requires the selection of semi-rigid materials with excellent corrosion resistance, low shrinkage rate, low temperature shrinkage rate, and high tensile strength in the planning process of semi-rigid coatings. Form the bottom layer. In addition, using cement instead of lime as cement to stabilize gravel can have stronger crack resistance. It is necessary for construction personnel to treat the moisture content during the construction of the semi-rigid bottom layer to ensure that the moisture content of the mixture meets the engineering standard requirements. Through construction experiments, the thickness of the bottom layer was increased from 10 centimeters to 25 centimeters, and the throughput was three times that of earlier years. This requires the engineering unit to do as much as possible to improve the thickness of the bottom layer.
