Asphalt material composed by what? Asphalt is a petroleum by distillation of crude oil and other refined into gasoline, kerosene, diesel and lubricating oil residue after, and then processed. Divided solid, semi-solid and liquid asphalt, semi-solid bitumen Building bitumen waterproof material is the main raw material. Coke or coal tar is a byproduct of the production of coal tar, extract obtained after fractionation of various oily. The past is one of the main raw material coal tar pitch for basement waterproofing and anti-corrosion coating outside, but because it has some toxicity, environmental pollution, in recent years, the use of coal tar production of waterproof material is being restricted and eliminated. Modified asphalt is through blowing oxidation catalyst oxidation means plus plus sulfide and other non-metallic curing agent modified bitumen products. There is a small molecule hydrocarbons such as paraffin and the like in the asphalt, so that the physical properties of the asphalt pavement sensitivity to temperature, low temperature brittle asphalt, asphalt high temperature deformation, flowing; In addition, excess reactive groups, to reduce the anti-aging properties of asphalt. Thus, by means of the modified after making these small molecule hydrocarbon polymerization, reducing asphalt active groups, improve the physical properties of the asphalt bitumen production project in Jiangxi, serve to reduce the asphalt temperature sensitivity, improved heat resistance and the role of low-temperature properties; also improve the ability of bitumen molecules resistant to degradation fission, extending the life of the material. 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 company, providing customers with a full range of asphalt industry services, 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. 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 asphalt, 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, lane width 6m, 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. Same soil asphalt pavement road shoulder grassroots and cost, the surface should be laid in some asphalt gravel or coarse sand and gravel. If the lane is not wide enough, you need to reinforce part of the shoulder, provide lateral width to facilitate the asphalt road safety project bidding, Jiangxi, bitumen, asphalt road through the plant through the prices offered by the Nanchang Road asphalt highway engineering Limited. Nanchang Road through the asphalt highway engineering Limited (www.dt0791.com) strong, credible, transportation project in Nanchang, Jiangxi collaboration industry has accumulated a large number of loyal customers. The company better work attitude and continuous improvement through innovative ideas will lead the asphalt road and you hand into the brilliant, for a better future!
