Woven geotextiles are composed of at least two parallel rows of cotton yarn or paper-plastic products, one group along the longitudinal fabric of the loom in the direction of the direction is called warp, and one group is horizontally arranged called weft. Non-woven geotextiles are made of polyester yarn or polyester staple fibers through different machinery and equipment and processing technology to lay into a honeycomb shape, after needle and other processing technology, so that different chemical fibers are intertwined with each other and entangled with each other to make the textile standardized.

Adding an upper layer of asphalt to some aged cement pavement can mainly enhance the performance of the pavement, but it cannot enhance the bearing function of the pavement.

Working face: The flatness of the slope surface is related to the success or failure of grass planting protection in the geocell. The uneven surface of the slope is prone to stress concentration when laying geogrid cells, which can cause cracking of the grid welding points and cause cell stepping.

Both belong to geotechnical materials, a new type of environmentally friendly material. The difference between the two raw materials is that the geotextile is a brand new polyethylene resin particle extracted from crude oil by Sinopec, while the geotextile is made of polyester fiber or polypropylene fiber.

Geotextile is a new type of environmentally friendly building material, made from green polyester fibers needle punched. Has good mechanical properties.

If engineers encounter damaged geotextile plastic drainage boards during construction, do not waste them. They can be repaired, and the repaired geotextile can be reused. Perhaps our repair work after geotextile damage is not very professional.

Geotextiles have many functions, such as filtration, isolation, reinforcement, and so on. For example, filtering, isolation, reinforcement, and so on.

The permeability of geotextile is one of its hydraulic properties, which is reflected in its filtration and drainage properties. That is to say, when it is necessary to exert filtration and drainage functions, the permeability performance is the indicator to measure them.
