Description :

　　Anti cracking adhesive tape is a roll type anti cracking waterproof membrane, which is made of 2mm thick polymer waterproof film coated on anti wrinkle and anti heavy load polypropylene material, and then pressed and compounded together through strict processing. Anti cracking stickers are self-adhesive interlayer anti cracking and waterproof materials. This structure is an organic combination of several crack prevention and waterproofing measures, such as geosynthetic materials and stress absorbing layer materials, which are currently used separately on highways. It is an optimized combination and upgraded product of interlayer crack prevention and waterproofing materials on highways.

　　The mechanism of action of anti crack stickers

　　Reinforcement effect

　　The high-temperature resistant fabric on the surface of the anti cracking sticker has a high tensile strength, which can resist the tensile stress at the interlayer cracks, limit the development of crack width, and play a reinforcing role, thus enhancing the tensile strength of the local structural layers of asphalt pavement.

　　Energy dissipation buffering effect

　　The polymer in anti cracking adhesive tape is a material with certain viscoelasticity and good low-temperature flexibility. When laid between 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 crack is gradually attenuated to a wider range through the expansion of the good viscoelastic composite layer, which can absorb tensile energy.

　　Waterproof and anti-seepage effect

　　Crack resistant stickers are laid on the surface of interlayer cracks to form a complete waterproof and anti-seepage layer, which can block the infiltration path of rain and snow water, thereby reducing water damage to the road surface.

　　Self adhesive performance

　　This product has self-adhesive properties and is easy to apply. After removing the isolation film, it is directly bonded to the crack area. After being stabilized by a small compaction equipment, it is more firmly bonded to the road surface without displacement, which can meet the requirements of upper layer asphalt mixture paving construction.

　　Applying anti cracking stickers 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. Laying and pavement can isolate the base layer from the upper wear layer, thereby protecting the upper layer from multi-directional displacement and shear stress. It is used in highways, bridges, and airports.

　　Instructions for use

　　surface treatment

　　1. Clear away dust, water, and other debris adhering to the surface, and keep the road surface dry and clean.

　　2. Clean the cracks (joints) with a width between 519mm and fill them with sealant.

　　3. Clean the cracks (joints) and sunken areas with a width between 1950mm, fill them with adhesive sand, sealant or asphalt mixture, and compact them to the existing height.

　　4. Cracks or potholes with a width exceeding 50mm should be cleaned first, and then filled with adhesive sand or hot asphalt mixture and compacted to the existing height.

　　5. For cracks (joints) and sunken areas with different heights, leveling treatment should be carried out.

　　6. Clean or level the protrusions on the bridge deck and road surface until they are smooth.

　　Environmental conditions

　　1. It should be used under conditions where the surface temperature is equal to or greater than 21.

　　2. If the surface temperature is below 10 degrees Celsius, it is recommended to use a warm fire to bake the crack resistant adhesive tape, which should be flat, wrinkle free, and not have curled edges.

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

　　4. It is recommended to roll at least three times with a rubber roller after laying the polymer anti cracking adhesive.

　　5. After the laying is completed, vehicles can pass through. However, the interval between laying and the upper layer should not exceed 24 hours.

　　Asphalt overlay

　　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 40mm.
