geotextile production line said that geotextile is a chemical fiber product, and its raw materials are polypropylene (polypropylene), polyester (polyester), polyester (polyester), etc. In terms of product categories, it can be divided into two categories: woven (woven) fabrics and non-woven fabrics. The so-called woven fabric is the fiber obtained from the polymer, and then spun into thread, in the loom woven into a regular organization of the cloth. The so-called non-woven fabric is made of synthetic fibers without textile process, directly through needle bonding, thermal bonding, chemical bonding and so on. Because the raw material of geotextile is polypropylene and other chemical fiber products, it has the advantages of strong chemical resistance, high melting point and high strength, while non-woven fabric has the advantages of low cost, simple process, high output and no obvious direction of tensile strength, so non-woven fabric is widely used in the world.

Precautions in Geotextile Construction:

1. Surface Treatment. First of all, clean the road, so that there is no debris on it, try to clean with water. Repair the cracks larger than 0.6cm on the pavement. Asphalt concrete, asphalt sand and cement concrete can be selected as repair materials according to unused conditions.

2. Apply adhesive coating oil. Use a hot asphalt distributor to spray viscous oil on the road surface. Geotextile production line manufacturer said that the amount of oil depends on the oil absorption rate of the road surface, and the general amount is between 0.9-1.2 kg/m. Oil number is generally more than 60 asphalt is good. If the method of applying oil twice is adopted, the initial dosage is 0.5-0.7 kg/m, and then asphalt geotextile is laid, and the oil is sprinkled on the asphalt geotextile, and the dosage is 0.4-0.5 kg/m.

3. Pave the sidewalk. Geotextile production line manufacturer said that when laying geotextile , it is necessary to ensure that the coil is at a certain height from the ground. After the geotextile is stretched and leveled, it will be glued with bonding oil, leveled with a brush, and rolled with a steel roller. When laying geotextile, as far as possible straight, can give a certain tension. When the bonded fabric has wrinkles larger than 1.27cm, it should be cut with a knife and overlapped in the laying direction. When laying fabric at road corners, it should be cut on the inside of the fabric corner and overlapped in the laying direction. The lap length between cloth nets is required to be 4-7.5cm

4. Lay stone chips. Geotextile production line manufacturer said that sprinkled gravel chips on the fabric after it was fully combined with the adhesive layer oil. Generally, the gravel can be melon seeds or medium coarse sand. The amount of gravel depends on the oil immersion on the surface of the fabric, generally 2m 3/Km; About.

5. Geotextile production line manufacturer said that when is laying geotextile in a large area, fixators including fixing nails and fixing iron sheets can be considered according to the specific situation at the transverse lap of the cloth. The fixed nail can be cement nail and nail, the nail is about 8cm long, and the fixed iron sheet is 1mm thick and 3cm wide. Nail fixed nails can be fixed with a hand hammer or nail gun, and high-speed nail gun can be used in the case of a relatively secret room at the grass-roots level. At the same time, the geotextile should be kept dry. If it rains, it should be completely dry before laying. When laying geotextile, construction personnel shall not smoke. When the artificial asphalt used to bond the geotextile cools, the upper layer is made. When the geotextile is saturated and the hot asphalt has not cooled, do not drive on the geotextile, and do not turn around and brake on the laid geotextile.
