Geotextile also known as weaving geomaterial is a kind of composite geomaterial with good permeability which is acupunctured or knitted using composite fiber. Cloth-like product have the general width of 4-6 meters and a length of 50-100 meters. Geotextile can be divided into woven and the non-woven geotextile. The product has excellent permeability, acquired, durability, which can be widely used in railway, highway, movement hall, DAMS, hydraulic structures, hence hole, coastal shoal, reclamation, environmental protection and other projects. Basically have acupuncture nonwoven geotextile and lectricity crack membrane silk weaving geotextile.
-Using geotextile good air permeability, make water flow through, thus effectively interception of soil erosion; -Geotextile has good performance, it can guide water soil formed within the drainage channels, soil structure in excess liquid and gas discharge; -Using geotextile enhance soil tensile strength and resistance to deformation ability, strengthens the building structures stability, to improve soil quality; -Effective will focus on the stress diffusion, transfer or decomposition, prevent soil by external force and destruction; -To prevent the lower sand, soil and concrete between mixed; -Meshes not easy jam-because not stereotypes formed reticulation fibrous tissue degeneration and sports should be; -High permeability - in soil under the pressure of water, can still maintain good permeability; -Corrosion - with polyethylene fiber or polyester, etc as raw material, acid and alkali resistant, no corrosion, not eat by moth, oxidation; -Construction is simple - light weight, easy to use, simple construction.
Special polyester filament sintering highway surface roughness geotextile
New pavement semi-rigid stable layer, old rigid or asphalt concrete pavement leveling spraying sticky layer oil, paving mechanically burn bandanas (rough surface facing upward) was deeply layer oil, and sand, rubber roller compaction rolling, paving asphalt concrete cover surface, burning bandanas formation waterproof interlining, make old pavement layer crack through interlayer stress abreaction, can avoid extended to surface, make the pavement improve operating quality and prolong the service life.

The specification is divided according to the mass per unit. When what you need is between the two specifications in the form, calculate it using method of interpolation. When it exceeds the index, negotiate it; Specific index depends on the design and contract; We will not announce you if the technical data is corrected; Other products can also be manufactured according to your need.
