Construction Notes 1, construction of cement concrete must be dry. The base surface is wet and rain, snow, not construction. 2, after the construction must be rubber tire roller cracking stickers pressure dense to prevent rainwater from entering the crack control paste adhesive surface prior to paving asphalt concrete. Slope greater than 5%, cracking stickers width should not be greater than 330mm. Paving the underlying asphalt concrete may be a small amount of slippage should be promptly repaired, will not affect the quality of the project. 4, the total thickness of the paving asphalt concrete should not be less than 6cm. 5, when the temperature is below 5 degrees Celsius, not construction. Crack Prevention paste the crack control mechanism "YN-crack control paste" selection bending performance, high tensile strength, permanent anti-corrosion of the reinforced fiber material as the substrate, the upper and lower coverage the special ratio processing of high-performance viscoelastic material its crack control mechanism is as follows: When the deformation of the cracks in the cement concrete due crack control paste "the tensile strength of the substrate is greater than the adhesive strength, so that the original concentration of stress, obtained dispersing through ripstop paste covering layer prevent and reduce the possibility of cracks in asphalt concrete. indicators affixed to the physical characteristics of self-adhesive crack control and crack prevention paste when adjacent concrete plate, up and down repeatedly in a certain range shear due to enhanced fiber has excellent fracture resistance and extension, therefore, difficult to make "crack control paste" broken, to maintain the "Crack Prevention paste" original stress dispersion function. 3. "the crack control paste" having a good self-adhesive closure. cut off surface water erosion cement concrete slab joints (cracks), to ensure a solid foundation to reduce the factors cracks. affixed to the physical characteristics of self-adhesive crack control and crack prevention paste Indicators crack paste "500g weight hammer, 500mm height under the impact, then the constant pressure of 0.3MPa water pressure by 0.5h, crack control paste impermeable Features excellent crack control effect 2mm thickness "YN-crack control stickers , tensile strength ≥ 600N50mm, the product elongation of ≥ 30%. two cement concrete slab horizontal displacement of 1 mm (base slot width 4mm), crack control stickers can play a good role in mitigation and dispersed Having open closed 10000, "Crack Prevention paste" destruction of anti-permeability: YN crack control affixed by the manufacture of glass fiber and polyester modified asphalt concrete can withstand high temperature construction, high temperature stability will pavement to provide a continuous of no deformation of the waterproof layer, effective to prevent moisture penetration, so as to avoid damage caused due to moisture permeation Pavement with grassroots 3, has excellent low-temperature toughness, resistance to the upper and lower shear properties due to "crack prevention paste substrate soft, flexible, low temperature of -20 ℃ along glass rod ф20mm. bend 1800 material is not broken. "the crack control paste" vertical displacement 0.5mm (the base slot width 4mm paste in two concrete plates ), 10000 times by repeated up and down displacement, due to the "the crack prevention paste" having a good flexibility and elongation, crack control affixed "no damage (conventional design allows the values ??of the upper and lower displacement value is generally not greater than 0.06mm) 4. prevent and delay reflective cracking: YN crack control paste has very low elongation and high tensile strength, can effectively clear the road junction or cracks at the stress concentration, reduce expansion and upward reflection of cracks in the pavement, delaying the reflection cracks extend road service life, and greatly reduce the cost of road maintenance, the products are not only used for asphalt concrete base, is also applicable to the cement concrete base. asphalt pavement cracks Jingxi planing, does not completely eliminate base crack, as prevent crack (then) seam to expand, to avoid crack (then) seam reflection to the surface layer to prevent the infiltration of rainwater from the surface into the cracks, we developed crack resistance of the base crack polymer paste. 5, adhesive properties "Crack Prevention paste" cement concrete base and asphalt concrete surface with good adhesion, the bonding strength greater than 4Nmm bonding performance improved significantly after hot asphalt concrete Rolling, so that when the level of force, not easy to slip and damage under high temperature of 50 ℃, crack control the shear strength of the paste up to 0.15Map above. 6, "crack control paste under the surface self-adhesive waterproof airtight overburden greater than 1mm, combined with concrete after hot asphalt concrete shin and pressure completely, greatly improve the water tightness, to prevent the infiltration of surface water into cracks in the concrete plate, and to improve the stability of the foundation. especially when subjected to vehicles horizontal thrust, since the cover layer has a good self-adhesive and softness to ensure waterproof airtight. 7, the physical characteristics of the paste by the anti-perforation and good self-adhesive crack prevention and crack prevention Post indicators "crack control paste" 500g hammer impact heights from 500mm to the constant pressure of 0.3MPa water pressure by 0.5h, crack control stick "impermeable. convenient construction crack control paste construction method for self-adhesive cold construction as long as removing the release paper (film), you can paste the cement concrete base. convenient construction, speed does not cause pollution to the environment at the same time, the eco-friendly products product uses a new and road widening, reconstruction and other projects 2 old cement concrete pavement overlay the asphalt surface. 3 patch of asphalt pavement surface cracks, old asphalt road maintenance. 4. semi-rigid base contraction crack repair for airport runways, bridges, playgrounds, golf lane to provide enhanced layer features: 1, firm bonding easy to fall off, high and low temperature performance. 3, very unique "self-healing" function, self-healing small puncture damage, can automatically packing healing small cracks. 4, tear strength, excellent durability, can effectively prevent the re-expansion cracks. market after more than three years of investigation, most of them can be kept cracking is not passage of years is not damaged. 5 can effective handling of radioactive cracks and bifurcation cracks. 6, to facilitate construction without any equipment, only need a two small cars can be construction construction workers without professional training. 7, no material waste. 8, no equipment Investment in the construction process does not require any equipment.
