The warp-knitted composite reinforced crack-resistant fabric is a new type of geosynthetic material used in asphalt road construction and renovation to prevent reflective cracking, water damage, and enhance the road's load-bearing capacity.
The braided composite reinforced crack-resistant fabric is a mixture of glass fiber and polyester, which uniquely combines the strengths of both materials—glass fiber's strength and polyester fiber's flexibility. After absorbing asphalt materials, it forms a structural layer with physical properties of waterproofing, heat resistance, and corrosion resistance. It boasts high tensile strength, low expansion coefficient, good toughness, no long-term creep, and ease of installation; when combined with asphalt mix layers, it significantly improves resistance to low-temperature shrinkage cracking, heat-induced rutting, fatigue cracking, and reflective cracking, thereby extending the service life of the pavement.
Woven composite reinforced crack-resistant fabric, made of glass fiber and polyester, can withstand the high-temperature construction of modified asphalt mixtures. This high-temperature stability provides a continuous, non-deforming waterproofing layer for the pavement, effectively preventing water penetration and thus avoiding damage to the pavement layers and subgrade caused by water penetration.
The warp-knitted composite reinforced crack-resistant fabric features low elongation and high tensile strength, effectively alleviating stress concentration at pavement joints or cracks, reducing the expansion and upward reflection of cracks in the pavement, delaying the formation of reflective cracks, extending the service life of roads, and significantly lowering maintenance costs.
Applications of the knitted composite reinforced crack-resistant fabric:
New constructions and road widening projects.
2. Overlaying asphalt on old concrete cement road surface.
3. Patching asphalt pavement surface cracks, repair of old asphalt roads.
4. Repair of semi-rigid base shrinkage cracks.
5. Provide reinforcement layers for airport runways, bridges, sports fields, golf cart paths, and more.
