Geotextile: Innovative Power for Highway Construction and Maintenance
In the construction and maintenance of modern expressway, geotextile is playing an increasingly important role.
Geotextile, a permeable geosynthetics made of synthetic fibers by acupuncture or weaving, has become a new favorite in the highway field with its excellent performance. It has good isolation, filtration, drainage, reinforcement and protection functions.
In the construction process of the highway, the geotextile can effectively isolate different soil layers, prevent the soil from mixing, and maintain the stability of the soil layer. For example, in the filling section, the geotextile can separate the fill soil from the original foundation soil to avoid the mutual penetration and interference of the two, so as to ensure the uniform settlement of the subgrade.
Filtration function is also a big advantage of the geotextile. It is able to prevent the loss of soil particles, while allowing the free passage of water. In the side ditch and drainage system of the highway, the application of geotextile can prevent the sediment from blocking the drainage channel and ensure the smooth drainage.
In addition, the reinforcement of the geotextile can enhance the tensile strength and deformation resistance of the soil. When building expressways on the soft soil foundation, laying geotextiles can improve the bearing capacity of the foundation and reduce the settlement and cracks of the road surface.
Geotextiles also excel in highway maintenance. It can be used to repair road cracks, prevent further infiltration from rain, and extend the service life of the road.
With the continuous progress of technology, the performance of geotextile is constantly improved, and its application prospect in the field of highway will be broader. It is believed that in the future, the geotextile will continue to provide strong support for the safety, comfort and lasting operation of the highway.
