The structural layer of asphalt pavement engineering consists of multiple layers such as surface layer, bottom layer, cable asphalt manufacturer's bottom layer, and laying.
1. The surface layer is directly affected by repeated wheel loads and various natural factors, transferring the load to the structural layers below the bottom layer. Therefore, it is necessary to meet the requirements of surface functionality and structural application. The surface layer can be single-layer, double-layer, or three-layer. The two-layer structure is called the outer structure, and the bottom structure; If a three-layer structure is used, it is called the surface layer, middle layer, and bottom layer.
The outer layer should have maintenance functions such as flat density, anti slip and wear-resistant, and stable use. It should also have characteristics such as high temperature guide rail, low temperature cracking resistance, and aging resistance. The middle and bottom layers should be fine and completely impermeable, with high-temperature mechanical properties such as rail resistance, shear resistance, and fatigue resistance.
2. The bottom layer is the primary load-bearing layer, and cable asphalt manufacturers need to have stability, durability, and high throughput. The quality can be single-layer or double-layer, with double-layer being called the upper and lower layers. Whether it is asphalt mixture, bottom layer particles, semi-rigid bottom layer, or rigid bottom layer, relatively high physical and mechanical performance indicators are required.
3. The bottom layer is a secondary load-bearing layer, installed below the bottom layer, and together with the outer layer and the bottom layer, it receives multiple load effects on the wheels. Therefore, the technical requirements for the bottom layer data may be slightly lower than those for the bottom layer data. The bottom layer can also be divided into upper and lower layers.
4. The gasket is a structural layer that is located between the bottom and the bottom, providing hydrophobic, waterproof, antifreeze, and anti fouling effects, reducing the modularity ratio between layers, and reducing the stress on the semi-rigid bottom of the bottom.
