Why use geotextiles in road maintenance?

1, increase friction: geotextile has a larger coefficient of friction, construction on the one hand, to prevent vehicles from skidding, on the other hand, to prevent the geotextile from being rolled up by the vehicle, damage to the road surface.

2, better quality: the so-called pavement maintenance cloth, not only the material is not good, but also inconvenient to use, a waste of manpower and money, while the geotextile does not have such a problem.

3、Construction is easy and time-saving: geotextile is light in quality and high in strength, as long as the construction team is skillful, the construction doesn't need to waste too much time.

Is filament geotextile widely used in engineering?
Filament geotextile can be used in water conservancy project, embankment, anti-filtration of berm, road berm, seepage control, foundation protection of highway, railroad, airport runway, anti-filtration, drainage, earthy slopes, road reinforcement of retaining wall, and so on.

Drainage: soft foundation treatment of harbor project, beach embankment, seaport terminal breakwater reinforcement, drainage.

Polyester filament geotextile has been applied in the field of infrastructure construction and is being widely used in various fields.

The price of filament geotextile is calculated on the basis of grams per square. The strength of the same covered filament geotextile will not be impaired after a period of time, and the strength of the uncovered filament geotextile will be impaired after a period of time. Filament geotextiles are used in a wide range of projects such as household landfills, waste disposal, highways, railroads, embankments, coastal beaches and so on. The use of filament geotextile has a certain life span, so we need to extend its service life by some methods. In the storage process, the integrity of the label and the integrity of the data should be linked, only with the correct method of storing filament geotextile, to ensure that its performance is not affected, and there will be no problems in the use of the process. Filament geotextile is used in barrier construction engineering, filtration construction engineering, drainage construction engineering, reinforcement construction engineering, protection construction engineering and so on. The tendril of filament geotextile is covered with opaque material to prevent UV aging. Therefore, after the filament geotextile is laid, it should be covered with some rare earth elements, which will prolong its service life. The rolls of filament geotextile should be stacked in a flat place without water accumulation, and the stacking height should not exceed the height of four rolls, and the identification sheet of the rolls can be seen. So how should filament geotextile be stored? Filament geotextile rolls should be protected from damage before installation and unrolling. The method of storing filament geotextiles is just as important as the method of using them, and I hope that you masters will not neglect it. To prolong the service life of filament geotextile, you should shorten the exposure time of filament geotextile in sunlight as much as possible, and cover the geotextile with rocky soil or deep water of more than 30cm in thickness, and add anti-aging agent in the raw material. The strength of filament geotextile with anti-aging agent added will only lose 25% when exposed to sunlight for a period of time. If there is a broken filament geotextile, it should be repaired in time so as not to affect the unbroken geotextile after being blown by the wind.

Composite geotextile products have good physical and mechanical properties, strong tear resistance, good deformation adaptability, puncture resistance, aging resistance, UV resistance, oil and salt resistance, acid and alkali resistance, corrosion resistance, high temperature resistance, low temperature resistance, non-toxic and harmless, long service life, etc., with good waterproofing, drainage, seepage control, moistureproof effect, width, thickness specifications complete, low cost, easy construction.
