Iron岭 Self-adhesive Asphalt Pavement Crack Tape Manufacturer

Crack Prevention Tape is primarily used in the construction and maintenance of new roadbeds for highways, general roads, and urban streets. It boasts high tensile strength, excellent flexibility, and surface adhesion, suitable for roadbeds to prevent cracks from reflecting to the surface layer due to temperature effects and vertical loads.Crack Tape features a reasonable multi-layer structure (2mm) that, when laid with hot asphalt mixture, the top layer's high-strength, heat-resistant fabric does not deform at high temperatures, ensuring the formation of a locally high-strength asphalt mixture layer; the upper coating's high polymer melts and seeps out of the fabric's gaps, bonding exceptionally well with the asphalt mixture; the lower coating contains sufficient high polymer to fill the base surface's hollows upon melting, enhancing the bonding strength to the base; the stability of the lower coating and the backing ensures the formation of a relatively even thickness composite interlayer.Meets the requirements for crack resistance and waterproofing. The product is self-adhesive, making it easy to install. After removing the release film, it can be directly bonded to the crack area. Once firmly pressed with a small compaction device, it forms a more robust bond with the road surface, preventing any displacement. This meets the construction requirements for laying upper asphalt mixtures. Apply the crack-resistant tape to asphalt concrete surfaces that have cracks or are peeling.Reduces and isolates the thermal contraction stress on the road surface, thereby minimizing the tendency for cracks to reflect through the surface layer. Laid over the road, it separates the subgrade from the upper wearing course, thereby protecting the upper layer from the effects of multidirectional displacement and shearing stress, suitable for highways, bridges, and airports.
