Singeing geotextilePET continuous filament spunbond needle punched nonwoven geotextile MANUFACTURER
110g/sqm --200g/sqm,the tensile strength ≥8kn/m,precede the PP or PET made short fiber geotextile, mainly for asphalt road construction.
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.
