sphalt oil → handMoping natural cooling → open traffic . ② modified emulsified asphalt coldconstruction Modification of emulsified asphalt is a mixture of liquidcold materials, machinery equipment without special request, after the stirring scene of artificial joints Guatu letters (at least three times) → preparations for the construction technologyartificial joints → Banliao → people on the Guatu → → curing → secondary Guatu → curing → three Guatu → Kang → opening of traffic (curing time l5 ~ 20 min). ⑶ traditional repair method for repairing and slotted the parison ① to the traditional repair method, whether it is reused to transport oil or pieces of asphalt emulsion asphalt irrigation joints, although Oxfam j equipment almost no input costs, lower cost of the initial application T, but with the surface temperature of contraction and the grassroots up to 1 year, after the repair of cracks and joints location of the original irrigation recracking, fire accounted for more than 80 percent efficiency, so the second year of rerepair This regular maintenance, not only increased the cost of conservation and conservation of the frequent traffic of the operation will cause inconvenience and anxiety umbrella factors. Every five years Yanmi rtotal cost of about l5 yuan. ② the slottedrepair, although the initial investment cost of higher construction equipment. Higher initial construction cost, but greatly extend its service life, sealing cracks in the effective and efficient artificial increase, the use of 5 years later, slottingrepair cracks in the efficient handling of 85% in five years for each of the Yanmi Cost is about ll yuan ③ traditional repair method for dealing with microcracks and small and mediumsized cracks in the temporary emergency treatment: barrelrepair cracks in the small and mediumsized carry out a repair can be maintained for more than five years, benefited from a repair for many years. slurry seal Slurry seal technology for the new and old road of aging, cracking, smooth, loose, pits and other diseases can play a role in the prevention and maintenance, so that the road waterproof, antislide, formation, the rapid increase wear resistance. In recent years. Because slurry seal of the standardization, standardization, improve construction quality and reduced costs, slurry seal has been widely used in the Highway Maintenance early on. modified emulsified asphalt slurry seal Modification of emulsified asphalt is a hightemperature flow, low temperature brittle fracture resistance, weatherability, abrasion resistance, ageing resistance excellent road paving material, the lower coefficient of the road flooding, road management of the disease early, increasing the road And the formation of friction coefficient, a very good role. Modification of emulsified asphalt slurry seal from the water quality is a polymer modified asphalt emulsion and rolling brokenintensive materials, mineral fillers, additives and water treatment consisting of surface layer,。
