Custom Elastic Pavement Round Cream Repair Black Anti-cracking Stickers

Functions:

1. Reinforcement. The high-strength and high-temperature-resistant fabric on the surface of the crack-resistant surface has greater tensile strength, can effectively resist the tensile stress at the cracks between layers, limit the development of the crack width, play a reinforcing role, and improve the tensile strength of the local structural layer of the asphalt pavement . 2. Energy dissipation and buffering. The polymer in the anti-cracking patch is a material with a certain degree of viscoelasticity, and has good low-temperature flexibility. When laid between the asphalt pavement layers, it is equivalent to setting up a composite layer with good viscoelasticity under certain low-temperature conditions. The tensile stress at the location is gradually attenuated to a wider range through the expansion of the good viscoelastic composite layer, which can play a role in absorbing tensile energy. 3. Water-proof and anti-seepage effect. Anti-cracking stickers are laid on the surface of the cracks between layers to form a complete water-proof and seepage-proof layer, which can cut off the rain and snow water seepage path, thereby reducing road water damage.
