Pavement repair crack prevention sticker - crack prevention sticker 25KN national standard - Shengyue geotechnical material

Description :

　　Road surface repair anti cracking patch (also known as anti cracking patch) is a composite of high molecular weight polymer based on asphalt, high-strength tensile tire base, and high-strength fabric that is resistant to high temperatures and compatible with asphalt. Applying it to asphalt concrete surfaces that produce cracks or peeling can reduce and block the thermal shrinkage stress acting on the road surface, thus reducing the tendency of cracks to reflect through the surface layer. When laid on the road surface, it isolates the base layer from the upper wear layer, thereby protecting the upper layer from multi-directional displacement and shear stress, and is used for highways, bridges, airports, etc. 5. Use a roller to press the anti cracking patch firmly to the ground to ensure that it is integrated with the road surface, without bubbles or wrinkles.

　　Product performance

　　1. Having all the characteristics of APP/SBS.

　　2. It has high heat resistance and good high-temperature shear resistance, which can ensure that the waterproof layer is not damaged during the paving or pouring of high-temperature asphalt concrete.

　　3. Strong resistance to breakage, able to withstand the puncture of equipment bare rolling and granular materials during construction.

　　4. High tensile strength, anti cracking patch for road surface repair, high elongation rate, anti cracking patch for Puyang road surface repair, and strong bonding strength with concrete.

　　5. No foaming or layering, good impermeability, able to withstand the repeated effects of driving and dynamic water pressure.

　　6. Good acid, alkali, and salt resistance, not affected by freeze-thaw cycles.

　　1. Good performance.

　　8. Good waterproof effect.

　　Requirements for the use of pavement repair crack prevention stickers and crack prevention stickers

　　(1) After the correct installation of anti cracking stickers, they should be closely integrated with the construction of the upper layer to avoid moisture and rain.

　　(2) After laying the anti cracking sticker, emulsified asphalt and other adhesive oils can be spread according to the construction specifications of hot asphalt mixture. To prevent vehicles or pavers from sticking to the anti cracking sticker, some fine-grained crushed stones or mixtures can be sprinkled on top of the anti cracking sticker.

　　(3) The thickness of hot asphalt mixture laid on the anti cracking patch should be greater than 30mm.

　　Environmental conditions

　　(1) It should be used under conditions where the surface temperature is not less than 10 ℃.

　　(2) If there is overlap during the laying process, the overlap length is 50mm. It cannot exceed the overlap of two layers.

　　(3) It is recommended to roll the polymer anti cracking adhesive tape 2-3 times with a rubber roller after installation.

　　(4) After the laying is completed, vehicles can pass through, but the interval between the laying and the upper layer should not exceed 24 hours.
