Geotextile of basalt fiber use basalt fiber that strong alkali-resisting as raw material, then it weaves grille cloth, last it backouts forming after bituminous settled. Specification Mesh size : 25*25mm, 38*38mm, 5*5mm, 10*10mm, 50*50mm Application Dam and road bed strengthening Permanent bearing foundation reinforcement of long airport runways, parks and wharfs Soft soil foundation reinforcement Retaining wall in bridge abutment, highway, lag disposal pit, etc. Advantages Geotextile of basalt fiber have performance of ultrahigh-temperature and ultralowtemperature. It can prevent bituminous orad surface from causing crack. It has high tensile strength and don?t have long-term creep and have good heat stability. It possesses good consistency with bituminous mixture and stable performance of physical chemistry. It can well resist bioerosion and climate change. The mixing temperature of bituminous mixture is high to cover 190?, so geotextile of basalt fiber that resistants to elevated temperatures have very competitive superiority in variety of geotextile at present.
