Winter asphalt concrete construction time requirements: a close attention to the weather conditions, a good grasp of the construction time, wind, rain, snow, the weather may not be carried out road construction hot mix asphalt. 2 Winter asphalt concrete construction shall be carried out at high temperatures during the day, night construction is strictly prohibited. Paving time should be at 9:00 to 16:00 conduct, so fast discharge, fast spreading, fast rolling. Asphalt project schedule at 11:00 am to 3:00 pm for. Winter compacted asphalt concrete paving requirements: 1 requires more than one road asphalt paver joint operations much money to ensure that the whole lot of paving asphalt surface forming minimize seams. 2 should adopt the high density of the paver, before paving screed to preheat. 3 Try to keep a continuous paving. 4 good measure wind envelope. 5 RCC paving hot pursuit, with the pressure to do with the spread. 6 edge in some areas, such as the right path to be a small vibratory rollers or vibrating plate compactor ram. Manhole edge of the area but also a vibrating plate compactor, compaction 7 after a hot iron supplement construction is completed, immediately do one seal layer on the asphalt surface layer and the layer below the surface layer. Nanchang Road highway Engineering Co., Ltd. (Nanchang asphalt | Jiangxi asphalt | Asphalt Pavement Nanchang | Jiangxi colored asphalt | Jiangxi spraying emulsified asphalt | Jiangxi asphalt works | asphalt pavement construction, Jiangxi | Jiangxi asphalt concrete mixing station), factory mixing station was established in 2009 year, is a professional road asphalt industry chain integrated companies bitumen, asphalt industry to provide customers with a full range of services to business areas mainly for asphalt pavement construction, spray emulsified asphalt, sales and processing, asphalt pavement construction equipment leasing business, the spirit of hard work, the principle of sincere and trustworthy, asphalt pavement construction industry has been recognized by the owners and customers. 1. Principles of asphalt pavement drainage low-grade highway, cross slope asphalt works in general should be around 3% to 4%. When located in a small longitudinal or twisted road ultra relaxation segment, the minimum composite grade of not less than 0.5%. 2. At the intersection of Highway drainage difficult area, road drainage design should meet the technical requirements of driving dynamics and drainage in the discharge port should be set before the intersection. 3. For the longitudinal larger lots, special parts inside lane curve, vertical curve recess, bridges and other high embankment ends, to prevent too much water on the roadbed shoulder centralized, slope erosion, can be partially set up when the water curbs . 4. Set all drainage facilities, in addition to meet drainage requirements, should satisfy facilitate future maintenance and repair. 5. In order to reduce the surface water and groundwater across the layers, primary and embankment erosion break, quickly ruled out the water layer between the pavement structure, usually road drainage and pavement drainage system considered.
