Introduction

Polyester Geogrid Knitted With Non Woven Geotextile are knitted non woven composite comprising a non woven geotextile reinforced with high tenacity polyester yarns in two orthogonal directions.The high tenacity,high molecular weight,low CEG polyester yarns with high tensile strength and low creep performs the function of reinforcement and the non woven performs the functions of separation,filtration and drainage.Polyester Geocomposite is resistant to the chemical and biological radiation.The excellent drainage or in plan permeability enables an accelerated dissipation of excess pore water pressure.

Polyester Geocomposite are widely used for road and railway applications.These products provide the ideal combination of functions of separation between the granular base course layer and the soft and possibly saturated sub grade,filtration and drainage capability of polyester geocomposite allows free water flow,enabling accelerated dissipation of excess pore water pressure. It also prevent migration of fine soil particles from the sub grade into the base course.High strength with low creep of polyester yarns provides stabilization of sub grade and reinforcement of the base course layer.

Properties Of Polyester Geogrid Knitted With Non Woven Geotextile

*High tensile strength and low elongation

*High flexibility and drapability

*Good resistance to high temperatures

*Minimum viscous creep in order to assure long-term reductions in the incremental plastic deformation of the asphaly layer

*Easy to fix to the support layer with a tack coat spray and good adhesion to the support

*The connection between the upper and lower asphalt layers is assured by the tack coat,without creating any separation

Advantages Of Polyester Geogrid Knitted With Non Woven Geotextile

*Up to threefold increase in maintenance intervals

*Straightforward,cost-effective installation

*Excellent bond with asphalt layer thanks to bitumen coating

*Roll widths between 1-5m to match project required size

*Flexible,robust material

Application Of Polyester Geogrid Knitted With Non Woven Geotextile

*Asphalt layer reinforcement

*Paved and unpaved roads

*Load transfer platforms over saturated soils

*Railway,packing lots,airport construction

*Asphalt pavement reinforcement
