High quality and low price anti-crack patch in Luwan District, Shanghai

The anti-crack patch (also called anti-crack patch) mainly produced by the company 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. Applying it to the cracked or peeling asphalt concrete surface can reduce and block the thermal contraction stress acting on the road surface, thereby also reducing the tendency of cracks to reflect through the surface layer. It is laid with the road surface because it isolates the base layer from the upper wearing layer. As a result, the upper layer is affected by multi-directional displacement and shear stress and is used in highways, bridges, airports, etc. The main functions of anti-cracking stickers are:
: Isolation effect. Laying anti-cracking stickers isolates the cracked layer from the asphalt surface layer, avoiding direct contact between the cracked layer and the asphalt surface layer. The tensile stress of the cracks in the base layer cannot be directly transferred to the asphalt concrete surface layer, although the bonding force between the base layer and the surface layer is reduced. However, the polymer anti-crack sticker can make the upper and lower layers well adhered into a moving whole, which can jointly bear the vehicle load and is enough to prevent the relative displacement of the upper and lower interfaces and maintain continuity
: Reinforcement effect. The anti-crack sticker has a certain strength and can withstand a certain crack tensile stress. When the crack tensile stress increases and is greater than the tensile strength of the anti-crack sticker, the anti-crack sticker begins to deform. At this time, the layer begins to bear the tensile stress transmitted by the anti-crack sticker. The anti-cracking plaster layer will bear all the tensile stress of the crack. Obviously the anti-cracking plaster acts as a reinforcement. In this sense, it improves the tensile strength of the pavement structural layer.
: Energy dissipation buffering effect. The anti-crack sticker is a material with a certain extension. The polymer has good low-temperature flexibility and is laid between the asphalt pavement layers. The tensile stress of cracks in the base layer is set up with an elastic layer. The anti-crack polymer expands to a wider range to alleviate the cracks. The elastic interlayers with high stress intensity can absorb part of the tensile energy.
: Waterproof and anti-seepage effect. The anti-cracking polymer can form a complete water-proof and anti-seepage layer, which can block the penetration of road water into the subgrade, thereby protecting the strength of the base layer and preventing further deterioration of the base material quality. Anti-crack stickers used in asphalt pavement layers can effectively inhibit the upward propagation of cracks and play the anti-cracking and energy-absorbing effects of anti-crack stickers in actual projects.
Highway reconstruction project to prevent reflective cracks - overlaying self-adhesive anti-crack stickers. In addition to strong tensile stress, self-adhesive anti-crack stickers also have a certain waterproof function, which can prevent water damage to the road and reduce road cracking. the elements of. The goals and tasks of rural road development
In 2019, the city passed the implementation of the three-year action plan to focus on the construction of rural roads of not less than 100 kilometers (county and township roads, kilometers of village roads), renovation of dangerous bridges on county and township roads, and large and medium-sized dangerous bridges on village roads. Among them: the annual construction of rural roads shall not be less than 1.2 kilometers (km of county and township roads, kilometers of village roads), the reconstruction of dangerous bridges on county and township roads, and the expansion of large and medium-risk bridges on village roads. ) Renovate dangerous bridges on county and township roads, and extend the length of large and medium-risk bridges on village roads. The construction of rural roads should not be less than 1.2 kilometers per year (km of county and township roads, kilometers of village roads). Renovate dangerous bridges on county and township roads, and extend the length of large and medium-risk bridges on village roads. Improve security, drainage and other ancillary facilities to basically realize that there is a road connection between the township government station and the administrative village under the jurisdiction of the township with good road conditions and meeting grade requirements. Basically eliminate existing dangerous bridges on county and township roads and large and medium-sized dangerous bridges on village roads. Gradually open up inter-county connections. , Inter-rural dead-end roads and rural roads have significantly enhanced their supporting role in rural economic and social development. Warp-knitted composite reinforced anti-cracking tape, also known as anti-cracking tape or self-adhesive anti-cracking tape, is a new type of composite geotechnical material used in road construction and reconstruction to prevent reflective cracks, water damage and enhance the load-bearing capacity of the road surface. Anti-crack stickers have strong bending resistance, high tensile strength and permanent anti-corrosion.
Special functions of anti-crack stickers:
, firmly bonded 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 radial cracks and bifurcation cracks.
, Convenient construction. No equipment is required and 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 when heating joint filling material, high output per shift.
Excellent waterproofing effect due to its low temperature, gentleness and strong bonding force. After being pasted and compacted, a permanent seamless bonding layer is formed so that rainwater cannot enter the cracks in the base layer. The irregular, complex and changeable shape of the surface cracks seriously affects the appearance and waterproofness of the road surface. The anti-crack patch for highways can be used directly on the road surface, eliminating the disadvantages of slotting and filling joints in the past and avoiding secondary damage to the road surface. It is suitable for different grades of highways. Maintenance construction: This product is easy to construct, has strong adhesion, wide operating temperature range, long service life, and complete crack sealing
