Anti-cracking paste (also known as anti-cracking paste) is composed of asphalt-based polymer, high-strength tensile base, high temperature and high-strength fabric compatible with asphalt. Which is applied to the asphalt concrete surface which produces cracks or peeling, can reduce and block the temperature stress applied to the road surface. Therefore, it also reduces the tendency of the crack reflection to pass through the surface layer. As a result, Layer isolation, so that the upper layer from the multi-directional displacement and shear stress, for roads, bridges, airports and so on. Main performance, isolation effect. Laying the anti-cracking paste, the cracking of the surface layer and the asphalt surface isolation, to avoid the cracking surface and the asphalt surface of the direct contact, the grass-roots cracks tensile stress can not be directly transmitted to the asphalt concrete surface layer, , But the polymer anti-cracking paste can make the upper and lower layers of a good adhesion into a whole, together bear the role of vehicle load, enough to prevent the relative displacement of the upper and lower layers and maintain a continuous. Reinforcement effect. Anti-cracking paste has a certain strength, can withstand a certain degree of crack tensile stress, when the crack tensile stress increases and greater than the tensile strength of the anti-crack, the anti-cracking paste began to deformation, then the layer began to bear the anti-cracking paste Up the tensile stress. The crack-resistant surface will be subjected to all the tensile stresses of the crack, and it is clear that the anti-cracking effect acts as a reinforcement, and in this sense it improves the tensile strength of the pavement structure. Energy dissipation. Anti-cracking paste is a certain extension of the material, the polymer has a good low temperature flexibility, laying in the asphalt pavement, equivalent to set up a elastic layer, the base layer of cracks through the anti-cracking polymer extended to the polymer A wider range, so as to ease the stress at the crack, the elastic layer can play a part of the role of stretching energy. Water seepage prevention effect. Anti-cracking paste can form a complete water impermeable layer, can cut off the pavement water infiltration to the roadbed, thus protecting the strength of the grassroots, so that the nature of the base material will not further deteriorate. Anti-cracking paste for asphalt pavement layer can effectively inhibit the crack up, in the actual project to play anti-cracking effect of anti-cracking and energy absorption. best caulk for concrete cracks large garage pothole patching equipment slurry seal contractors north west affordable highway all round lifting work lights
