Why Geotextile Is Used in Road Construction

Road construction plays a crucial role in a country's infrastructure, directly impacting people's travel safety and national economic development. Among the various materials used in road construction, geotextile has become an indispensable material due to its unique properties and extensive applications. This article explores the usage and significance of geotextile in road construction.

Basic Characteristics of Geotextile

Geotextile is a geosynthetic material made of synthetic fibers, boasting excellent tensile strength, elongation, corrosion resistance, aging resistance, and water permeability. These characteristics enable geotextile to fulfill multiple functions in road construction, meeting various needs.

Applications of Geotextile in Road Construction

Reinforcement

Geotextile can be used as a reinforcement material to enhance the stability of soil or fill materials. By laying geotextile in the soil or fill, it effectively improves the road's bearing capacity and resistance to deformation, reducing issues such as subsidence and cracks during use.

  Isolation

Geotextile provides excellent isolation between different layers of the road. It prevents the mixing and infiltration of different materials, maintaining the integrity and stability of the road structure. For instance, laying geotextile between the subgrade and the pavement layer prevents subgrade materials from entering the pavement layer, affecting its service life.

  Filtration

Geotextile acts as a filter, allowing water to pass through while preventing soil particles from being carried away by waterflow. This protects the road structure from erosion and scouring, crucial for maintaining its stability.

  Drainage

Geotextile's excellent permeability quickly drains water from the road structure. This reduces the humidity of the structure, preventing road diseases caused by excessive moisture. Additionally, drainage enhances the road's frost resistance and durability.

  Impermeability

In situations requiring waterproofing, such as between the road foundation and groundwater, geotextile offers impermeability. It effectively prevents groundwater from entering the road structure, protecting it from the effects of groundwater.

Importance of Geotextile in Road Construction

  Enhanced Road Quality

Using geotextile significantly improves road quality. It not only enhances the stability and bearing capacity of the road but also reduces issues such as subsidence and cracks during use. This improves the road's service life and safety.

  Reduced Engineering Costs

Although geotextile has a relatively high price, using it in road construction reduces overall costs. It reduces raw material usage and simplifies maintenance procedures, reducing maintenance costs. Therefore, in the long run, using geotextile reduces the total cost of road construction.

Environmental Protection and Energy Saving

Geotextile is an environmentally friendly and energy-saving material. Its excellent corrosion resistance and aging resistance allow it to be used for a long time without frequent replacement. Additionally, it reduces the impact of road construction on the environment, such as soil erosion and ecological protection.

In conclusion, geotextile plays a vital role in road construction due to its extensive applications and significance. With technological advancements and the continuous development of engineering techniques, geotextile's usage in road construction is expected to become more extensive and profound in the future. Haoyang specializes in the production of high-quality geotextile products designed specifically for road construction.
