Shandong Jining pouring cold asphalt pavement agent

Pouring cold asphalt pavement agents - no heat, no slits, cracks easily control the road, the most convenient method of repairing a crack Products 1, the product uses agents pouring cold asphalt pavement is a new asphalt pavement crack filling products. , mainly for asphalt pavement crack repair timely infusion can also be used in cement concrete pavement crack repair and expansion joints filling, perfusion compared with traditional hot asphalt, no heating, no slits, construction speed, fast open traffic, Strong environmental protection, conservation and low cost advantages. 2. Physical and chemical characteristics Physical state: viscous oily dark brown liquid, flammable. Stability: long-term storage and under normal conditions of transport. Risk phrases: Do not swallow and inhale, gets into the eyes, rinse immediately with plenty of water and taken to hospital, do not use open flame, petroleum products for allergy sufferers do not touch. Storage: Do not store in high temperature or direct exposure to the sun, away from fire and sealed storage. Shelf life: 12 months, 2 Product performance 1, simplistic: no complex construction machinery construction, no slits, no heating, clean up after the crack can prime; surface dry after construction can be achieved within 30 minutes, two within an hour traffic, after the infusion is completed, the surface can be open to traffic immediately spreading sand. 2, sticky malleable: material aging will not lose adhesion, it will not change from the seam wall cracks; after solidification up to 8 times the length of the extension, when the crack becomes large can be followed longer, greatly reducing the probability of secondary cracking, and has strong toughness, can effectively support the crack walls, gnawing edges and prevent the collapse of the wall, thereby preventing cracks expand and spread. 3, docile nature: material is a flowable liquid, can maximize the perfusion to the bottom of the crack, especially through Cracks through the band, which can effectively block moisture diffusion inside; "in the extra slow" solidification mode, This material is unique technology breakthrough, after rapid drying surface traffic, and internal slow solidification, retain a certain plasticity at the crack changes, you can make more docile pouring between agents and cracks. 4. Adaptability: Pouring cold asphalt pavement agent may be -60 ℃ - + 60 ℃ under construction, not climate, hydrology and seasonal conditions, care of asphalt pavement at any time throughout the year; also avoid the traditional process heating smoke, dust and irritating odor when pollution asphalt for municipal construction requirements of environmental protection. Third, technical indicators Polymer Modified composition uniform appearance black liquid Solid content% ≥90 impermeability 0.3Mpa impermeable heat resistance ℃ 140 ℃ not flowing, sparkling and plain frost resistance -60 ℃ without cracking ductility ≥9.5 mm adhesive strength ≥0.9Mpa Alkali 2% sodium hydroxide solution soak for 15 days did not change the impact of high temperature shear ≥0.44Mpa free of debris, peeling and cracking dry drying schedule 30 minutes three Dosage 1, the basic Requirements: 1.1 material used asphalt cold pouring agents, per kilogram of crack perfusion general 4-6 meter. 1.2 Governance width of 1mm-15mm, 3mm depth asphalt pavement cracks above is appropriate. 1.3 Construction conditions: temperature should be at -60 ℃ - between + 60 ℃, rain and snow can not construction. 1.4 construction workers before construction understand the use of this material. 1.5 Construction machinery: mixer or hand mixing tool (hand drill modification), high pressure blowing apparatus, the bottom surface of cleaning tool, trowel several. Water bottles and the like containers using mechanical or manual pouring perfusion can be, the case is available with a manual infusion diversion mouth can be. 2, repair Pre-treatment: first cracks in parts of the surface dust and other debris to clean out the crack, blown clean with high pressure hair dryer, if loose parts together to clean up. Never work with water, if water should first be sucked out of the water and allow to dry before construction. 3, material mixing: Open after materials Packaging machinery or stick, stir, special attention precipitate drums stir up the bottom of all, the case of winter construction, the mixing process can increase the flow of material, easier construction. 4, the construction method: mixing good material into the pouring device or a container with a diversion in the mouth, can be directly poured into the cracks, if after a width exceeding 15mm, adding an appropriate amount in the material aggregate stirring perfusion repair, according to the aggregate size of the crack size determines the maximum diameter not exceeding the crack width and depth dimensions of one third is appropriate. 1.2 construction experience: A. Try to crack along parts of perfusion, avoid material spill too much, resulting in patches too wide and aesthetic impact; B. above the road surface that may be appropriate to set aside a sinking space; C. If the crack is more lenient, After perfusion reason naturally sink material will appear depressed, then you can carry on a secondary infusion can enhance repair effect; D. If the crack is difficult perfusion narrow slit, available scraper or putty knife scraping the material to crack site to use materials strong bonding and ductility can equally serve for crack repair and seal action; E. perfusion after spreading sand on the surface, to prevent the material is not dried before being taken away by the wheel, traffic can open immediately. 5, health and traffic control temperature at -20 ℃ -20 ℃, the two to three hours to open traffic, drying time outside of this temperature range will be extended, if the conditions allow try to extend the opening time traffic helps material improved performance. After perfusion, spreading sand on the surface can open traffic immediately, but the crack need to wait for the second infusion of secondary injury after the completion of sand.
