Geotextile is widely used in many fields. It is also used in highway maintenance?Generally speaking,the main function of laying geotextile on the highway is to keep moisture,so as to help the highway extend its service life.

Three applications of Geotextile in highway maintenance:

1. Strengthening effect for pavement: no matter asphalt pavement or concrete pavement, flexible pavement or hard pavement has strengthening effect. Compared with traditional pavement, it not only consumes less money, but also delays the generation of ground cracks, and the corresponding service life is longer.

2. Waterproof and thermal insulation: there are many specifications of geotextile. For a certain thickness of geotextile, it will form an isolation layer when it is bonded with the adhesive layer of asphalt pavement, and then play a role of isolation and protection for the foundation.

3. Moisturizing: when the highway is just repaired, the ground should be moisturized, because the hardening of cement cannot be separated from water. If the moisturizing is not in place, it will affect the strength of cement and then affect the service life of the highway. Geotextile has a good water storage property. The use of Geotextile for pavement maintenance can ensure the wetting of cement pavement and prevent cement cracking. Geotextile has a good moisturizing effect on the highway.

What are the advantages of using geotextile in highway maintenance?

1. Increase friction: the friction coefficient of geotextile is relatively large, which can prevent the vehicle from slipping on the one hand and prevent the geotextile from being rolled up by the vehicle and damaging the highway surface on the other hand.

2. Better quality: the so-called pavement maintenance cloth in the past is not only of poor material, but also of poor durability, which is not good for the maintenance of the ground. Sometimes it even needs to be constructed many times. For enterprises and construction personnel, it will cause a great waste of manpower and capital, while the geotextile will not show this situation.

3. Simple construction and time saving: the geotextile has good construction convenience. Generally, the geotextile is 6m wide and 100m long, with light weight, high strength and good durability. As long as the construction team's technology is in place, the construction does not need to waste too much time. Compared with the traditional highway maintenance with straw cover, geotextile has the characteristics of fast and convenient construction.

4. Compared with other pavement maintenance products, geotextile has the characteristics of low price, which can save the cost of pavement maintenance.

Finally, the geotextile can be reused. The geotextile can be reused and reused in pavement maintenance, so as to reduce the cost of pavement maintenance.
