What is asphalt bitumen, is a high viscous organic liquid, black surface, can be soluble in carbon disulfide. Many of them will be in the form of asphalt or tar existence. Bituminous coal can be divided into bitumen, petroleum bitumen and natural asphalt are three: which is a byproduct of coking coal tar pitch. Asphalt is the residue after the distillation of crude oil. Natural asphalt is stored in the ground, forming a seam or some accumulation in the crust surface. Tar pitch is to form the crude extract obtained in the fractional distillation method, which has the highest boiling point, and the heaviest crude material in the crude oil, and therefore will be found in the bottom of the fractionation column. The form of tar pitch, it is the organic matter (mostly coal), obtained after dry distillation treatment substance. Asphalt and more will be used in buildings, such as paved roads. Asphalt and gravel roads are paved called asphalt. Bitumen is a natural or artificial production of construction materials. It mainly consists of asphalt binder and graded aggregate composition. Mainly used in road surfacing and road works reinforcement, high-rise buildings in floor coverings, Hydraulic sealing material. In some cases also for waste disposal engineering seal. For reasons of technical and economic aspects of engineering, asphalt member has a different hierarchy, including asphalt carrier layer, link layer of asphalt and asphalt surface. Layers of different thicknesses and according to location, close the main structure for providing different carrying capacity. Chemically, asphalt concrete is a thermally inert material after plasticity. Nanchang Road highway Engineering Co., Ltd.

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. Asphalt shall be carried out at high temperatures during the day in winter when the two asphalt concrete construction, 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 multiple colored paver road asphalt joint operations, to ensure the entire 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.

Asphalt Pavement design principles and the basis of the design of the road is the village road, village road surface should be based on traffic volume and composition, functions, local materials and natural conditions, combined with comprehensive design roadbed, so economical and suitable. Meanwhile, the village road surface should have good stability and sufficient strength, smooth surface should meet, skid and drainage requirements. Village Road lane (including the wrong lane) should be paved roads. Pavement design and reinforcement in the form of soil shoulder of the road embankment width 6.5m, 6m wide lane asphalt road construction program, soil shoulder width of 0.5m. By local natural conditions and Hui County Department of Transportation Planning pavement structure is divided into three layers, the top layer of asphalt macadam, primary use of cement stabilized gravel, grass-roots using natural gravel. Due to the low level road, with no set curbs and emergency strip, when the roadbed width of 4.5m or unreasonable, as the lots in the road, every lane about 200m should be set wrong, wrong lane effective length of not less than 20m, in the wrong lane should be located at both ends of the transition section is not less than 10m. Soil and road shoulder grassroots same should be laid on the surface of some coarse gravel asphalt or gravel. If the lane is not wide enough, you need to reinforce part of the shoulder, provide lateral width to facilitate road safety road asphalt | asphalt concrete road through price (certified) | Gian provided by Nanchang Road asphalt through the asphalt highway engineering Limited.
