Functional Characteristics of Anti-Crack Tape
1. Strong bonding, not easily脱落.
2. Excellent high and low temperature performance.
3. A distinctive "self-healing" feature that can autonomously mend minor puncture damage and automatically fill and heal minor cracks.
High tear resistance, excellent durability, effectively prevents cracks from spreading further.
5. Effectively treats radioactive cracks and fissured cracks.
6. No material waste, low cost.
7. Fast construction speed, simple construction techniques, convenient and quick; no environmental pollution or harm to workers during the construction process.
8. Significant economic benefits, with minimal labor input, no equipment investment, and no heating material required, resulting in high output per shift.
9. Excellent waterproofing effect, due to its low-temperature flexibility and strong adhesion, it forms a seamless adhesive layer after pressing, preventing rain from entering the base cracks.
Mechanism of anti-crack tape:
(1) Stress Absorption and Crack Resistance. The high molecular self-adhesive crack-resistant tape, placed within the asphalt surface layer, can dissipate the pressure from the lower layer beneath the wheel contact and the stress from the area beyond the wheel load edge. It forms a buffer zone between the two stress-bearing areas, gradually reducing stress at this point and minimizing the damage caused by stress concentration to the asphalt surface, thereby effectively extending the lifespan of the road.
(2) Overall Stability. The high molecular self-adhesive crack-resistant tape, with its excellent tensile strength and adhesion, can connect the sides of the lower cracks together, forming an integrated protective layer 75mm-100mm wide.
(3) Excellent resistance to low-temperature cracking. Due to the high tensile strength of the high polymer self-adhesive crack prevention tape, its application in the asphalt base can enhance the lateral tensile strength of the base, withstand greater tensile stresses without damage. Even if cracks occur locally, stress concentration at the crack location is dissipated through the transmission of the high polymer self-adhesive crack prevention tape, preventing the cracks from spreading to the surface layer and damaging the road surface.
Crack Prevention Tape Features:
Self-adhesive crack-proof tape boasts superior waterproofing, crack resistance, and operability compared to traditional crack-proof products. Made from natural materials, it is resistant to corrosion and abrasion, easy to recycle, and is an environmentally friendly product that aligns with China's sustainable development policies currently being implemented. It can withstand temperatures below 200°C, ensuring that it does not deform or shift under the high temperature of 165°C in asphalt mixtures. It has excellent compatibility, high strength, good bonding properties, and strong load-bearing capacity, making it adaptable to the trend of increased traffic volume and significantly extending the lifespan of road surfaces.
