Polypropylene/Polyester Woven Geotextiles on Road
Function
Seperation
It can isolate building materials of different physical properties (such as soil and sand , soil and concrete...), to keep two or more materials from being lost or mixed ,maintain the overall structure and function of materials , enhance carrying capacity .
2. Filtration
When water flows from fine soil into coarse soil, good air permeability and water permeability of geotextiles can make water flow through, and effectively prevent soil particles, fine sand, small stone, etc., so as to keep soil and water engineering stable
3. Drain away water
good water conductivity ,drainage channels can be formed inside the soil to drain excess liquid and gas from soil.
4. Reinforcement
Enhance the tensile strength and deformation resistance of soil , increase the stability of the building structure ,improve soil quality
5. Defense
When the water flow scour the soil ,it can effectively disperse the water flow force , prevent the soil from being damaged by external forces ,and protect soil
6. Puncture resistance
Combined with geomembrane , become waterproof and anti-seepage material , play the role of puncture prevention .
7. Good resistant to heat and cold temperature, anti-aging ,anti-corrosion ,
Geotextile- PET PP woven Geotextile
Part one: Description of woven geotextile
Made from PP(polypropylene) or PET(polyester) fiber by nonwoven needle punched manufacturing process. It has function of isolation, filtration, drainage, reinforcement, protection and maintenance etc.
Part Two: The Specification of woven geotextile
Part Three: The Application of woven geotextile
1 Separation
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different
granule pathway from the groundsill or other buildings.
2 Reinforcement
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability.
3 Protection
It prevents the bank from being washed out, protects the bank and the
bottom, prevents the water and soil from being washed away

Part one: Description of HDPE geomembrane
1. HDPE, LLDPE geomembrane is one double-surface membrane with flat and smooth appearance made from virgin resin with special formula.
2. HDPE ordinary rough geomembrane is single-surface or double-surface HDPE geomembrane with uniform and coarse appearance made from virgin resin with special formula.
3. HDPE glossy geomembrane has excellent impermeable and antifouling property and mechanical property; dimensional stability, chemical stability, thermal resistance and aging resistance are good; in the meantime, it also has excellent resistance to UV radiation.
4. HDPE ordinary rough or flat geomembrane has excellent impermeable and antifouling property and mechanical property; dimensional stability, chemical stability, thermal resistance and aging resistance are good; in the meantime, it also has excellent resistance to UV radiation. Rough geomembranehas large friction coefficient and skid resistance Is very suitable for pavement of side slopes surrounding refuse landfill and twice pavement of geotextile. In the meantime, it can also enhance bearing capacity and deformation resistance. It is usually used in such project at which surface of membrane of side slope need be covered with earth and large friction coefficient is required.
