What are the uses of roadbed slabs?

The main uses of roadbed slabs include the following aspects: ‌ : ‌ homogenizing the bearing capacity of the roadbed ‌ : The primary function of roadbed slabs is to evenly transfer the bearing capacity of the roadbed to the foundation, thereby enhancing the bearing performance of the pavement. The use of subgrade slabs can enhance the compressive strength and stability of the pavement, reduce pavement deformation and settlement, and extend the service life of the pavement ‌.

A smooth road surface can not only improve driving comfort and safety, but also reduce vehicle wear and fuel consumption, and lower operating costs ‌. Youdaoplaceholder0 slow down freeze-thaw damage ‌ : In the cold winter, the use of roadbed slabs can slow down freeze-thaw damage and extend the service life of the pavement. Under extreme climatic conditions, the subgrade slab plays an important role ‌. Youdaoplaceholder0 provides drainage performance ‌ : Roadbed slabs usually have good drainage performance, which can effectively drain rainwater and other water from the road structure, prevent water accumulation in the soil, keep the road dry, and improve driving safety ‌. The function of the ‌ isolation layer ‌ : The roadbed slab can serve as an isolation layer between the road and the soil beneath it, preventing harmful substances in the soil from seeping into the road structure and maintaining the cleanliness and safety of the road. Meanwhile, it can also prevent water and chemical substances in the road structure from polluting the soil, playing an environmental protection role ‌. Youdaoplaceholder0 Strong adaptability ‌ : Roadbed slabs can adapt to various geological conditions and traffic demands. Whether in complex environments such as soft soil foundations, mountain roads, or urban expressways, appropriate roadbed slab materials and construction plans can be selected to meet the needs of road construction ‌. Youdaoplaceholder0 Long-term stability ‌ : The subgrade slab can maintain stable performance during long-term use and is not easily affected by the natural environment and traffic loads. This enables the road to remain smooth, safe and comfortable for a long time.
