армированные стекловолокном асфальтовое покрытие геотекстиль

fiberglass asphalt coating reinforced geotextile Warp knitted reinforced coating geotextile is a completely new compound fiberglass anti-cracking material marketed by Nantong Jianhong Civil Engineering Materials CO.,LTD, which is a geosynthetic material processed through special technology. It can be widely used to guard against reflection cracks and water damage and strengthen load capability of road surface in construction and reconstruction of asphalt road surface. Warp knitted reinforced coating geotextile is a newly developed geosynthetic material following geo-textiles, geo-grids, and strip polymer, which has a good compatibility with asphalt mixture. Geo-grids have no function of waterproof. Geo-textiles can prevent water from penetrating, but their reinforcement and anti-cracking effects can’t be developed with low strength and bad creep resistance. However, warp knitted reinforced coating geotextile overcomes the shortcomings of the two. Warp knitted reinforced coating geotextile can effectively deal with road surface cracks and water damage on road or bridge surface. It is a mixture of fiberglass and polyester. This unique composition mixes good characteristics of fiberglass and polyester together ---- high strength of fiberglass and flexibility of polyester. It forms a structure layer after absorbing asphalt materials, which has physical features of waterproof, heat resistance, and corrosion resistance and also features of high tensile strength, low expansion coefficient, good flexibility, no long-term creep, and convenience for construction. It can lengthen service life of road surface because its functions of anti low temperature contraction cracking, resistance to high temperature rut, anti-fatigue and anti-tearing performance, and delaying reflection cracks have been distinctly improved after being compounded with asphalt mixture.

Between 20KN/M and 200KN/M, products with tensile strength in longitudinal or transverse direction can be randomly made, like 20/50, 80/40KN/M, etc according to your requirements; also we can manufacture geotextiles with tensile strength within the range in only longitudinal or only transverse direction, like 50KN/M in only longitudinal direction or only in transverse direction as you required. Compared with other geo-fabrics, warp knitted reinforced coating geotextile has features as follows: 1.) Low elongation, no long-term creep. Warp knitted reinforced coating geotextile has no creep, which ensures that the product can be used for a long term. Also it has good compatibility with many materials, especially asphalt and asphalt mixtures and high temperature stability. Its melting point is above 230°C, that is, under the temperature of 230°C, its physical and chemical properties are stable. Thus, there will be no influence on its stability when laying asphalt concrete under high temperature of 170°C. 2.) Good chemical stability The geotextile through special process can guard against all kinds of chemical and biological erosion, and also climate changes. 3.) Warp knitted reinforced coating geotextile and anti water coating oil form a layer of waterproof, so even if there are cracks on the surface, it also can effectively prevent water from penetration and ensure that the base materials will not be damaged by water. 4.) Warp knitted reinforced coating geotextile can be broken to pieces for recycling use. Application fields of warp knitted reinforced coating geotextile Application fields of Warp Knitted Reinforced Coating Geotextile 1.) Asphalt concrete overlay Warp Knitted Reinforced Coating Geotextile used in asphalt overlay can effectively reduce cutter construction time and depth. The thickness of asphalt overlay should be not less than 4cm. Suggest use modified asphalt concrete. 2.) Reconstruction of cement concrete road surface Warp knitted reinforced coating geotextile can be used for reconstruction of cement concrete road surface. Spread the geotextile before spreading asphalt concrete surface layer, which can effectively prevent reflection cracks, and it will be unnecessary to set base layer, especially used for city road whose standard height is limited. Suggest use modified asphalt concrete, whose thickness is not less than 10cm. 3.) Shrink Crack location in Half Rigid Base It’s impossible to avoid Shrink cracks in half rigid base, but in order to enhance its use ability, we can use warp knitted reinforced coating geotextile to amend cracks, which can delay and prevent base cracks from reflecting to surface layer after asphalt construction, and prevent rainwater from penetrating into base to cause base in frost boiling and accelerate damage of road surface. Suggest spread anti-cracking mat after sealing slurry but before spreading surface layer under asphalt. 4.) Bridge surface waterproof layer Warp knitted reinforced coating geotextile used on bridge surface can effectively prevent rain water penetrating from bridge surface to cause bridge surface to be damaged owing to rust of steel bars in steel plates or concrete soil plates. 5.) Old road expansion construction Warp knitted reinforced coating geotextile is used to sew cracks longitudinally between new and old half rigid base and between new and old asphalt layer in old road expansion construction.
