Henan crack prevention sticker crack prevention sticker crack prevention sticker specification

Description :

　　Crack resistant stickers are a type of road polymer modified material that combines tire base and high-temperature resistant fabric. They have a good effect on reflecting cracks on roads and have waterproof and crack resistant properties. Principle: Mechanical effect: Polymer materials, as a stress absorbing film, can increase the possibility of vertical cracks developing horizontally along the interface in the base layer, thereby delaying the time for cracks to reflect onto the road surface. Bridge effect: After the crack enters the asphalt concrete surface layer, the double-layer bridge effect of geosynthetic materials and high-temperature resistant fabrics gives the cracked section a certain tensile strength, reduces crack opening deformation, and lowers the concentration of tensile stress in the crack. Interlocking effect: The ability to resist shear and load transmission in cracked sections. Asphalt based polymer materials have certain low-temperature properties, which can maintain their shape without changing at low temperatures, and have good waterproof effects to prevent water infiltration after road surface cracking. Advantages: Anti cracking stickers overcome the interface caused by the simple use of geotextiles and fiberglass grids for crack resistance, which affects the stress condition of the asphalt surface layer and affects the crack resistance ability; It also overcomes the problem of displacement and folding caused by the use of geotextiles and fiberglass grids during the paving process, which affects the adhesion of the upper and lower structural layers. It provides a good solution for using only asphalt based stress absorption film, which can only absorb stress but cannot resist residual stress and disperse stress. This unique structure enables crack resistant stickers to prevent cracks while also having a unique effect on waterproof infiltration, especially for ice water infiltration after road surface frost cracking, with good low-temperature performance

　　The engineering characteristics of anti cracking stickers include: high strength and no directionality; Low elongation and no long-term creep ensure that the material can be used for a long time; It has good compatibility with asphalt and asphalt mixtures, and the melting point of crack resistant adhesive fabric is at 200 ℃. Its physical and chemical properties are stable at 200 ℃, so its stability is not affected under hot laid asphalt concrete at 170 ℃; Good chemical stability, the treated anti cracking adhesive can prevent various chemical erosion, biological erosion, and climate change; The modified asphalt material in the bottom layer of the anti cracking sticker has good adhesion with asphalt. During construction, it forms a waterproof layer after absorbing the adhesive layer oil. Even if there are cracks in the surface layer, it can prevent surface water infiltration and ensure that the base material is not damaged by water; It can be crushed for use, and during milling, it will be crushed into very small fibers to enhance the performance of RAP.
