Geocells have broad application prospects and significant advantages in paving. It can effectively improve the performance and stability of the road surface, reduce construction costs and environmental impact, and provide a reliable and economical solution for road construction.

The application of geocells in paving has significant advantages. The following is a detailed introduction to its use in paving:

Ⅰ.Basic concepts and structure
Geocell is a three-dimensional network structure made of reinforced HDPE sheets or other polymer materials that are welded with high strength. It unfolds into a honeycomb shape and can be easily retracted. It only needs to be folded for transportation, making it easy to carry and store.

Ⅱ. Road paving application
1. Roadbed enhancement:
Geocells are mainly used for roadbed reinforcement on highways, urban roads, railways and airport runways. Its honeycomb-like network structure can disperse pressure, thereby improving the pressure resistance of the road surface. By filling the geocell with filler (such as sand and gravel), the load can be effectively and evenly distributed, reducing the concentrated effect of load on the subgrade, and reducing the risk of subgrade settlement and deformation.
2. Soft foundation treatment:
Geocells can be used as an effective reinforcement measure when paving on soft soil foundations. It can increase the anti-lateral limit and anti-sinking capabilities of the roadbed and improve the stability of the roadbed. For example, in the reconstruction project of Provincial Highway S366 in Guangdong Province, the method of geocells + graded gravel was used to widen the old road, which effectively solved the problem of the old road not having soft foundation treatment.
3. Drainage performance:
The geocell is designed with drainage holes inside, which can speed up the drainage of accumulated water inside the roadbed and keep the roadbed dry, thereby reducing the impact of water on the stability of the roadbed.

Ⅳ. Advantages and effects
1. Save material costs: The use of geocells can save a large amount of materials, such as sand and gravel, thereby reducing the cost of paving.
2. Improve pavement performance: Geocells can enhance the stability of the roadbed and improve the pressure resistance and service life of the pavement.
3. Environmentally friendly and beautiful: Geocell materials can be recycled and reused, and the construction is simple and fast, which helps to reduce environmental pollution during the construction process. At the same time, after filling with suitable filler, different plants can also be planted to improve the landscape effect.
