Geotextiles have many advantages and specific details in highway construction, mainly reflected in the following 7 aspects:
1、Reinforce soil stability: Geotextiles can effectively reinforce soil and improve soil stability. In highway construction, especially under weak foundation conditions, the use of geotextiles can increase the anti-deformation and anti-settlement capabilities of the roadbed.
The main method used by geotextiles to reinforce land stability in highway construction is by enhancing the tensile strength and deformation resistance of the soil. The following are specific reinforcement methods:
(1)Foundation treatment: Before carrying out roadbed construction, the foundation needs to be treated first. This may include removal of loose or organic material, proper filling and compaction. Ensure that the base layer is uniform and tight, which is conducive to the effective application of geotextiles.
(2)Laying geotextiles: Geotextiles are usually laid between the various layers of the subgrade, especially between the fill layer and the base layer. The fabric must be smooth and wrinkle-free, and the coverage area must match the design requirements. When laying, be careful to avoid sharp objects to avoid damaging the geotextile.
(3)Cross-Lamination: For requirements requiring greater strength and stability, multiple layers of geotextile can be laid in a cross-lamination manner. Cross-lamination increases overall tensile strength and stability.
(4)Fastening and Attachment: Geotextiles need to be securely fastened to the foundation, usually using ground nails or other fastening devices. The connection points between the fabrics also need to be strong and reliable to ensure that each layer of geotextile forms an integral structure.
(5)Combination with soil: One of the main functions of geotextile is to combine with soil to form a whole. This requires maintaining sufficient soil penetration at the interface between the fabric and the soil to ensure that the geotextile and soil are closely combined to form a strong composite.
(6)Construction management: Strict management and monitoring are required during the construction process to ensure the correct use and effectiveness of geotextiles. Reasonable construction sequence and construction quality assurance are crucial to the reinforcement effect of geotextile.
Through the above reinforcement measures, geotextiles can effectively improve the tensile strength, deformation resistance and overall stability of the subgrade soil, thereby enhancing the stability of the land and extending the service life of the subgrade.

2、Anti-erosion and prevention of soil loss: Geotextile has anti-erosion properties, which can effectively prevent soil erosion by water flow and rainwater, and reduce the risk of soil loss. This is critical to protecting highway slopes and maintaining the integrity of the roadbed.
The main role of geotextile in resisting erosion and preventing soil loss in highway construction is to slow down water flow, stabilize soil, and prevent soil from being washed away and eroded through its protective and filtering functions. Here are ways geotextiles can resist erosion and prevent soil loss in highway construction:
(1)Covering bare land: During construction or repair, if there is exposed land surface, it can be covered with geotextile to form a protective layer. This can effectively prevent wind and water erosion from eroding the soil.
(2)Prevent water erosion: Geotextiles can be placed on slopes and ditches to prevent water erosion. It slows the flow of water and reduces its impact on the soil, thereby reducing the potential for erosion.
(3)Filtration Function: The filtration function of geotextile prevents soil particles from being washed away while allowing moisture to pass through. This helps maintain soil stability and reduces soil erosion.
(4)Strengthening ditches: Along highways or on slopes, geotextiles can be used to strengthen the structure of ditches, prevent water flow from forming cut ditches, and reduce erosion.
(5)Combined with vegetation: Geotextiles can be used in combination with vegetation to form an ecological protection system. The roots of vegetation can be anchored into the soil with geotextiles, providing additional protection against erosion.
Maintain construction sites: On construction sites, use geotextiles to cover construction areas, especially temporary exposed land, to reduce the risk of erosion.
The combination of these methods can effectively reduce soil erosion and loss, protect land resources during highway construction, and maintain the stability of infrastructure.

3、Improve the bearing capacity of the roadbed: The use of geotextiles can increase the bearing capacity of the roadbed, reduce the settlement of the roadbed, and improve the stability and durability of the road surface. This is crucial for highway projects under high traffic loads.
Geotextiles can be used to improve the bearing capacity of roadbeds in highway construction, mainly through the following methods:
(1)Increase the stability of the roadbed: Geotextiles can be used to enhance the stability of the roadbed and prevent lateral spreading and subsidence of the roadbed material. By laying geotextiles at different levels of the subgrade, the overall stability of the subgrade can be improved.
(2)Dispersed load: The use of geotextiles can effectively disperse the load and reduce the stress concentration on the surface of the roadbed, thereby reducing the subsidence and deformation of the roadbed. This is essential to improve the load-bearing capacity of the roadbed.
(3)Anti-permeability and anti-scouring: Geotextiles have certain anti-permeability and anti-scouring properties, which can prevent moisture from intruding into the interior of the roadbed, slow down the loosening of the soil, and improve the compactness and consistency of the roadbed.
(4)Inhibiting the growth of herbaceous vegetation: Covering the surface of the roadbed with geotextile can effectively inhibit the growth of herbaceous vegetation, prevent its roots from penetrating the roadbed, and reduce the risk of roadbed deformation and loosening.
(5)Prevent differential settlement of roadbed: In roadbed design, geotextiles can be used to build layered structures to prevent differential settlement of different levels of roadbed. This helps maintain the smoothness and load-bearing capacity of the roadbed.
(6)Combining geogrids: The combination of geogrids and geotextiles can form a reinforcement layer that improves the shear strength of the soil, thereby enhancing the overall load-bearing capacity of the roadbed.
In actual construction, it is necessary to select appropriate types and specifications of geotextiles according to specific engineering conditions and requirements, and rationally design construction plans to achieve the effect of improving the bearing capacity of the roadbed.

4、Drainage and anti-infiltration: Geotextiles can be used to improve the drainage performance of the roadbed and prevent groundwater from penetrating into the roadbed. This helps prevent moisture from damaging the subgrade structure and increases the service life of the pavement.
In highway construction, geotextiles are used for drainage and anti-seepage purposes, which are usually achieved in the following ways:
(1)Choose permeable geotextile: In order to achieve drainage effect, you can choose geotextile with good water permeability. Permeable geotextiles have an open structure that allows water to penetrate and drain away from the geotextile, preventing water from being retained within the subgrade structure.
(2)Applied to different levels of subgrade structure: Geotextiles are usually used at different levels of subgrade structure to meet different engineering needs. For example, geotextiles with good water permeability can be used in the surface structure, while geotextiles with strong anti-penetration properties can be used in the underlying structure to achieve drainage and anti-penetration effects.
(3)Reducing the groundwater level: In some cases, by taking measures to reduce the groundwater level, the drainage burden of the geotextile can be reduced and the drainage effect can be improved. This may include appropriate water table lowering before works begin.
(4)Adopt transverse and longitudinal drainage measures: Combined with geotextiles, transverse and longitudinal drainage measures can be designed. Horizontal drainage removes water laterally through drainage pipes, drainage channels and other structures, while longitudinal drainage removes water longitudinally through the drainage performance and structure of the geotextile itself.
(5)Reasonable design and construction: In actual construction, it is necessary to ensure the correct laying and connection of geotextiles to reduce possible damage and leakage. A properly designed construction plan can give full play to the drainage and anti-seepage effects of geotextiles.
(6)Use in conjunction with other drainage materials: Geotextiles can be used in conjunction with other drainage materials (such as drainage pipes, drainage boards, etc.) to improve the overall drainage effect. The synergistic effect can further enhance the drainage and anti-seepage properties of the subgrade.
Through the above methods, geotextiles can effectively drain water and prevent seepage during highway construction, ensuring the stability and long-term service life of the roadbed structure.
