Anhui Liu'an anti-crack patch self-delivery

Anti-cracking stickers are made of reinforced fiber materials with good bending resistance, high tensile strength, and permanent anti-corrosion as the base material, covering the top and bottom of the base material with high-performance viscoelastic materials processed with a special ratio. This product has self-adhesive construction and can be directly applied to cracks. Anti-crack stickers are mainly used on asphalt pavements with damaged cement pavements

, dust and water adhering to the surface must be clear Debris keeps the road surface dry and clean.
The cracks (joints) with a width between 1 and 2 must be cleaned and filled with sealant.
The cracks (joints) and sunken areas with a width between 1 and 2 must be cleaned, filled with mortar, sealant or asphalt mixture and compacted to the existing height.
Cracks or pits that exceed the width must be cleaned first and then filled with mortar or hot asphalt mixture and compacted to the existing height.
. Cracks (joints) and sunken areas with different heights must be leveled.
. The protrusions on the bridge deck and road surface must be cleaned or leveled until they are smooth.
Functional characteristics:
, The bonding is firm and not easy to fall off.
, Good high and low temperature performance.
. The unique self-healing function can self-heal minor puncture damage and automatically fill and heal minor cracks.
, High tear resistance and excellent durability, which can effectively prevent cracks from expanding again. After more than three years of market research, most of them can last for more than a year without cracking, shifting or damage.
, can effectively treat radioactive cracks and bifurcation cracks.
, Convenient construction. No equipment is required, only a small car and two people are needed for construction. Construction workers also do not need professional training.
, No material waste.
, No equipment investment. No equipment is required during construction.
, Fast construction speed can seize favorable construction opportunities.
, The construction technology is simple, convenient and fast. During the construction process, it will not pollute the environment and cause harm to workers.
, obvious economic benefits: low labor investment, no equipment investment, no fuel input to heat the joint filling material, high output per shift.
. Excellent waterproofing effect. Due to its good low-temperature flexibility and strong bonding force, it forms a permanent seamless bonding layer after being pasted and compacted, so that rainwater cannot enter the cracks in the base layer.
Construction technology of anti-crack stickers:
According to the width of pavement cracks (joints), the specifications of the anti-crack stickers usually include:, and three types (can also be customized according to customer requirements)
Above For wide cracks (joints), use at least the anti-crack tape. For the cracks (joints) below, use at least the anti-crack tape. Use an electric brush or hair dryer to clean the cracks (joints) that use the anti-crack tape. The surface of the cracks to be treated must be smooth (cracks with a wider width must be filled with polymer sealant first) without large protrusions, depressions, looseness, gravel or traces of oil, grease and other dirt. If there are large pits, they must be filled. .
Tear off the isolation paper on the back of the anti-crack sticker and stick the anti-crack sticker flatly on the road surface with the non-adhesive side facing up and taking the crack (joint) seam as the center line. When the temperature is lower than ℃, it is necessary to apply glue or bake before pasting.
If you encounter irregular cracks (joints), you can use a paper knife or scissors to cut the anti-crack stickers and paste them according to the direction of the cracks (joints). However, there should be an overlap between the anti-crack stickers and the anti-crack stickers.
Use a roller to press hard and iron the anti-crack sticker to the ground to ensure that the anti-crack sticker is integrated with the road surface without bubbles or wrinkles.
After the construction of the base layer adhesive anti-crack sticker is completed, try to protect the completed road surface to avoid contamination and damage to the surface of the anti-crack sticker.
Spray the sticky layer oil overlay mixture.
Note: In areas with cold or large temperature differences in the Northeast and Northwest, the anti-cracking stickers can be pasted after spraying the adhesive layer oil (the emulsified asphalt must wait until the emulsification is broken).
Precautions when constructing anti-crack stickers
It is not suitable to construct when the temperature is below ℃.
The road surface must be dry and no construction is allowed in rainy or snowy weather.
When the slope is greater than %, the width of the anti-crack sticker should not be greater than 1%.
The total thickness of paved asphalt concrete should not be less than .
When the height difference between the adjacent sides of the area where the anti-cracking tape is laid is greater or there are many potholes, it is necessary to level the area before paving it to prevent the anti-cracking tape laid in the depression from being damaged by gravity. The leveling material can be leveled with epoxy mortar or asphalt mixture.
After construction, the anti-crack sticker must be pressed tightly to prevent rainwater from entering the adhesive surface of the anti-crack sticker before paving asphalt concrete. If heavy rain is expected before paving asphalt concrete, sealant should be used on both sides of the anti-cracking patch.
. Vehicles are not allowed to roll over and turn around on the anti-crack patch.
