Features 2mm thickness of excellent crack control effect "YN-crack control paste, its tensile strength ≥ 600N50mm the product elongation ≥ 30%. When the two cement concrete slab horizontal displacement of 1mm (base slit width of 4 mm), the crack control stickers can play a very good mitigation and dispersion. Open closed 10000 times, "the crack control paste" destruction. Anti-permeability: YN crack control paste from the manufacture of glass fiber and polyester, can withstand the high temperature of the modified asphalt concrete construction, high temperature stability will pavement to provide a continuous deformation of the waterproof layer, effectively prevent moisture penetration, so as to avoid the result of water infiltration and damage to the pavement grassroots. 3, has excellent low temperature flexibility, resistance to the upper and lower shear properties due to "crack control paste soft" matrix, flexible, low temperature of -20 ℃ along the ф20mm the glass rod. Bend 1800 material is not broken. When the paste in two cement concrete slab crack control paste "up and down displacement of 0.5mm (base slot width 4mm) 10000 after repeated vertical displacement due to the crack control paste has good flexibility and elongation, crack control paste "destruction (conventional design allows the value of the vertical displacement value is generally not greater than 0.06mm). Prevent and retard reflective cracking: YN the Crack Prevention paste with low elongation and high tensile strength, can effectively clear the road junction or cracks at the stress concentration, the lower extension of cracks in the pavement and is reflected upward delayed reflection cracks to extend road service life, and greatly reduce the cost of road maintenance. This product is not only used for asphalt concrete base, also applies to the cement concrete base. Asphalt pavement cracks Jingxi planing, does not completely eliminate the base crack to prevent the crack (then) sewn expanded (pick) seam reflection to the surface layer to avoid split, and also to prevent the infiltration of rainwater from the surface into the cracks, we developed the primary cracks polymers crack resistance paste. 5 good adhesive properties of the crack control stick "with cement concrete base and asphalt concrete surface at the same time has good adhesion, the bonding strength greater than 4Nmm adhesive properties after hot asphalt concrete Rolling substantial improved when the level of force, is not easy to slip and destruction. 50 ° C high temperature conditions, crack control the shear strength of the paste up to 0.15Map above. 6, waterproof and airtight due to "crack control paste under the surface of the self-adhesive covering greater than 1mm, after hot asphalt concrete shin and pressure completely combined with cement concrete, greatly improve the water tightness, to prevent surface water infiltration to the cement concrete slab cracks, and to improve the stability of the foundation. Especially when a horizontal thrust by the traveling vehicle, since the covering layer has a good self-adhesive and softness to ensure waterproof airtight. Indicators of the physical properties and crack control paste, the anti perforation is good self-adhesive crack control paste "crack control paste" 500g weight, height from 500mm under the impact, then the constant pressure of 0.3MPa water pressure by 0.5h , "ripstop paste" impermeable. 8, to facilitate construction crack control paste construction method for the self-adhesive cold construction. Just remove the the isolated paper (film), you can paste the cement concrete base. Construction is convenient, fast. At the same time does not cause pollution to the environment, the eco-friendly products. The product uses a new and road widening reconstruction and other projects. 2 Old Cement Concrete Pavement asphalt surface. 3. Asphalt pavement surface cracks, patches, old asphalt road maintenance. Patches of semi-rigid base shrinkage cracks. Airport runways, bridges, playgrounds, golf lane reinforcing layer.
