Yunnan Yuxi anti-crack stickers are of good quality

Anti-crack patch, also known as [anti-crack patch], is composed of asphalt-based polymer, high-strength tensile tire base, and high-strength fabric that is resistant to high temperatures and is compatible with asphalt. It has good compatibility with asphalt pavement, high bonding strength, no brittleness, and no deformation at high temperatures. The construction operation is simple and flexible. Just remove the isolation paper and stick it to the road surface along the shape of the crack, and press it tightly to completely repair the crack. Exhaustive treatment can significantly extend the service life of the pavement. Anti-crack stickers are an organic and comprehensive application of several measures to prevent cracks on highways. They are also an upgraded product to prevent cracks and waterproofing on white-to-black highways. The polymer in the energy-dissipating buffering anti-crack patch is a material with certain viscoelasticity and good low-temperature flexibility. When laid between the asphalt pavement layers, it is equivalent to setting up composite layer cracks that also have good viscoelasticity under certain low-temperature conditions. The tensile stress at 0 can absorb tensile energy through the expansion of the good viscoelastic composite layer and gradually attenuates to a wider range.
Self-adhesive performance Anti-crack stickers are self-adhesive and easy to apply. Remove the isolation film and directly bond to the cracked area. Use small compaction equipment to stabilize the pressure and bond with the road surface more firmly without shifting. It can satisfy the upper layer of asphalt mixture paving. Paving construction requirements. Applying anti-crack stickers to cracked or peeling asphalt concrete surfaces can reduce and block the thermal contraction stress acting on the pavement, thereby also reducing the tendency of cracks to reflect through the surface layer. It is laid with the pavement because it isolates the base layer from the upper wearing layer. It is used to protect the upper layer from multi-directional displacement and shear stress and is used in highways, bridges and airports.
Product Features
, Excellent anti-cracking effect, excellent low temperature flexibility, good resistance to up and down shearing, good bonding performance, good resistance to perforation, good waterproof and sealing, convenient construction, fast speed< br/> Product use
Suitable for road crack prevention construction steps such as highways, railways, municipal projects, cement concrete pavement, white to black pavement, etc.
(1) Basic requirements for the road surface, the pavement panels must be stable. When the deflection value and edge height difference exceed the design requirements, the roadbed should be reinforced. , All kinds of gaps in the road surface are first filled with flexible materials, and the filling height is equal to the road surface. , Broken and loose pavement should be removed, and the defective parts should be repaired unevenly. Asphalt concrete or quick-drying cement concrete can be used as the repair material. , The road surface must be smooth, clean, dry and sand-free. (2) Apply base surface cleaner. Before applying anti-cracking stickers (anti-crack stickers), apply special base surface treatment (cleaning) agent on the cleaned base surface. Its purpose is to consolidate the residual dust on the base surface to improve the bonding effect of the product. After the special treatment {cleaning} agent for the base surface has dried {subject to non-stickiness}, the anti-cracking sticker {anti-crack} can be applied. (3) Apply the anti-crack sticker with the expansion joint (crack) as the center, select the anti-crack sticker according to the width required by the design, unfold it and place it on the area to be cracked, with the isolation paper side down, and then lift the anti-crack sticker in place. Tear off half of the isolation paper underneath and lay it forward so that the anti-cracking patch can be laid flat on the original base surface. (4) After the anti-cracking tape is laid, use sandbags or pressure rollers to flatten the anti-cracking tape. (5) When two pieces of anti-cracking stickers overlap, the overlap width should be pressed with a pressure roller to make the bonding firm. (6) Then lay fiberglass grating or directly pave asphalt concrete on top of the anti-cracking plaster.
