 NO.2:Singeing geotextilePET continuous filament spunbond needle punched nonwoven geotextile

1.Characteristic : with high intensity and powerful ant corrosiveness, great friction factor, low percentage elongation, good performance in heat resistance and permeability.2.Use:prevent the water from encroaching on the structure layer in the projects. This kind of geotextile is paved between asphalt layer and grave layer, after filled with glue oil, depending on its high tensile strength, it can act as waterproof layer and prevent reflex crevice.3.Application :road surface projects of high-grade highway and municipal road.4.
