What to do if the channel floor is not hardened?

You can find professional engineers to fill in the road. If the ground is not hardened, construction must be carried out in accordance with the "Uniform Standards for Quality Acceptance of Construction Projects". If the damaged area is not large, you can just find someone to bulldoze it. Warm reminder: Hardened roads are also called asphalt roads. Hardened roads (asphalt pavement) refer to mineral pavements mixed with asphalt paving materials. Asphalt materials improve the ability of paving particles to resist damage to the road surface from traffic and natural factors, making the road surface less dusty, impermeable and durable. Hardened road pavement structure: The asphalt pavement structural layer consists of surface layer, base layer, base layer and cushion layer. The asphalt pavement structural layer itself belongs to the category of flexible pavement, but in addition to flexible materials, the base layer can also be made of rigid cement concrete or semi-rigid hydraulic materials. The surface layer is the structural layer that directly bears the repeated effects of wheel loads and the influence of natural factors. It can consist of 1~3 layers. The surface layer should be provided with a non-slip, wear-resistant, dense and stable asphalt layer according to the usage requirements; the middle and lower layers should be selected according to the road grade, asphalt layer thickness and climate conditions. The base layer is set under the surface layer, and together with the surface layer, it spreads the repeated effects of wheel load to the base layer, cushion layer, and soil foundation, and plays the main load-bearing role. The strength index of base material should have higher requirements. The base layer can be set up with one or two layers depending on the needs of the highway grade or traffic volume. When the base layer is thick and needs to be constructed in two layers, it can be called the upper base layer and the lower base layer respectively. The bottom plate is set below the bottom plate, and together with the surface layer and the bottom plate, it bears repeated wheel loads and plays a secondary supporting role. The strength index of the base material is slightly lower than that of the base material. Depending on the grade of the road or the amount of traffic, the base can have one or two levels. When the thick base layer needs to be divided into two layers for construction, it can be called the upper base layer and the lower base layer respectively. The cushion is the structural layer between the base layer and the foundation, which plays the roles of drainage, water isolation, antifreeze, and antifouling.
