The price of Langfang Bazhou pavement anti-cracking material increased year-on-year. Anti-cracking treatment of cracks in the basement with highway cracking has good and economic benefits, and its effectiveness has been tested in practice. From the perspective of maintenance, it can fundamentally solve the problem of cracks in the base layer, which has value in a certain range. It has been applied to the daily maintenance and repair of cracked pavements in the base layer. In addition, it has important reference value for the highway to deal with the base cracks in advance during the construction period, which will greatly reduce the maintenance cost in the later period, and also has a good reference for the reflective crack problem that is common in municipal highways. The use of highways is very large, so the economic benefits and value are huge. Integrity-based Langfang Bazhou Road Waterproof and Anti-cracking Sticker is mainly used for the construction and maintenance of expressways, general highways and urban road pavements. It has high tensile strength, good toughness and surface viscosity. It is suitable for pavement base layer and can prevent the reverse layer of cracks caused by temperature influence and vertical load. Safety requirements reinforce effect. Road waterproof crack resistance has the strength, the tensile stress of the crack can withstand. When the crack tensile stress increases and is greater than the tensile strength of the road waterproof crack resistance, the road waterproof crack resistance begins to deform, and the surface layer begins to bear. The tensile stress transmitted by the road waterproof crack-resistant patch. The layer of road waterproof crack resistance will bear the full tensile stress of the crack. Obviously, the effect of road waterproof crack resistance to reinforcement is in the sense that it improves the tensile strength of the pavement structural layer. Improved quality At Yanan's high temperature, the pungent asphalt taste is attractive. An asphalt paver slowly moved forward in the main lane. Several people wore long sleeves, trousers, and rubber shoes with towels around their necks, hard hats on their heads, and a shovel and "T" in their hands. In the front of the paver of the type tool, an impervious water-proof and seepage-proof layer can be formed, which can be penetrated from the rain and snow and then reduce the road water damage. The product is self-adhesive, and the Langfang Bazhou pavement anti-cracking material is very convenient for construction. After removing the insulation film, it is directly bonded to the cracks.

Placing crack-resistant patches on asphalt concrete surfaces where cracks or falls can reduce and isolate the new processes and new materials such as the temperature-shrinkage stress crack-resistant patches that act on the pavement to improve the quality of maintenance. The energy dissipating and buffering polymer in the anti-cracking material is a material with fixed viscosity and good low temperature flexibility. It is laid between asphalt pavement layers, which is equivalent to setting a composite layer that also has good viscosity under constant low temperature conditions. As the tensile stress at the cracks expands, the viscous composite layer expands and gradually decays to a wider range, which can absorb the effect of tensile energy. After laying the crack-resistant patch, you can spread the adhesive layer oil such as emulsified asphalt according to the construction specifications of the hot asphalt mixture. To prevent the vehicle or paver from sticking the crack-resistant patch, you can sprinkle some fine-grained gravel or Mixture. The dissolving time of Langfang Bazhou is about 90 minutes. Adjust the flame size according to the melting temperature of the joint material. After the material is dissolved for about 30 minutes, start the generator and turn on the power switch of the discharge tube to give the tube heating (about 40 minutes). It can work after the material is melted and the temperature of the discharge pipe is reached. The pushing anti-cracking paste without the hand-held grouting pipe enables the material outlet to feed and grout the cracks; with the hand-held grouting pipe, the grouting pipe is used to straighten the cracks. Add materials at any time during the work process to ensure work continuity. The discharge flow of the asphalt pump is adjustable. When people are still thinking about what to do if there are many gaps on the highway, a new type of anti-cracking patch has begun on the market. This anti-cracking patch can not only protect our highways, but it is basically available on many urban highways. These self-adhesive road maintenance anti-cracking stickers, let's take a look at how good the quality of anti-cracking stickers!
