White 2.0mm Custom Elastic Pavement Round Cream Repair Black Anti-cracking Stickers
Anti-cracking Sticker
The anti-cracking paste (also known as the anti-cracking paste) is a composite of asphalt-based polymer, high-strength tensile tire base, high-temperature resistant and asphalt-compatible high-strength fabric. Sticking it on the asphalt concrete surface that produces cracks or peeling can reduce and block the temperature shrinkage stress acting on the pavement, so it also reduces the tendency of cracks to reflect through the surface layer. Paving and pavement will wear the base layer and the upper layer due to it The layers are separated to protect the upper layer from multi-directional displacement and shear stress. It is used for highways, bridges, airports, etc.
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.
