geogrid of basalt fiber instruction of products: of basalt fiber use basalt fiber that strong alkali-resisting and acid-resisting as raw material, then it weaves grille cloth, last it bakeouts forming after bituminous settled. of basalt fiber have performance of ultrahigh-temperature and ultralow temperature. it can prevent bituminous road surface from causing crack. it have high tensile strength and don’t have long-term creep and have good heat stability. it possess 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 over 190℃, so of basalt fiber that resistants to elevated temperatures have very competitive superiority in variety of at present. application area: civil engineering of road area. instruction of products: technology index of of basalt fiber areal density (g/m2) break(ing) strength (kn/m) elongation（ pourcent） breadth （mm） chaine weft 165 40 50 ＜3 1000 165 40 50 ＜3 1000 350 40 50 ＜3 1000
