We engineers all know that geotextile is an environmentally friendly material widely used in highway construction. Its use can enhance the stability of the highway base, improve the bearing capacity and durability of the highway.
Firstly, in order to ensure the stability of the highway subgrade, it is necessary to ensure that the geotextile is effectively connected with the road, bridge, and subgrade geotechnical materials when using it, so as to form a stable road surface. Therefore, a comprehensive investigation of the geotechnical conditions of the roadbed must be conducted before laying road materials, so that suitable geotextile models and specifications can be selected in case of soft or broken foundations, while ensuring the mutual coordination between the geotextile and the roadbed structure.
Secondly, when using geotextiles, attention must be paid to their usage methods and conditions. Geotextile must be laid strictly in accordance with design requirements, and at the same time, it needs to have strong resistance to environmental factors such as temperature changes, humidity changes, and wet dry alternation. When selecting geotextile materials, evaluation can be conducted based on the strength, quality, and applicability of the materials, and then suitable products can be selected according to actual needs.
In addition, during the use of geotextiles, close attention should be paid to their construction and maintenance to ensure their reliability and lifespan. During the construction process, it is necessary to strictly follow relevant construction specifications and procedures, such as direct administrative units and horizontal verification, edge fixation, joint treatment, etc. before laying, to ensure the correct laying of geotextiles. During maintenance, regular inspections and maintenance can be carried out according to the actual situation, and dust and dirt can be removed in a timely manner to ensure better performance of the geotextile.
Finally, the importance of geotextiles in highway construction cannot be ignored, as this material greatly enhances the bearing capacity and durability of highways. Therefore, the widespread use of geotextiles in highway construction can not only improve the bridge performance of highways, but also reduce the deformation of roads under high temperature or high humidity, while also reducing maintenance costs and saving paving costs.
