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 Asphalt how much a pound, 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. 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 segment of the longitudinal relaxation or ultra twisted road asphalt plant, 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. 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, asphalt pavement construction industry has been recognized by the owners and customers. Asphalt concrete pavement construction program complement an asphalt concrete paving: 1, based on cross-sectional width of the roadbed and paver functions, this time laying asphalt concrete paving construction using demi, demi Paving layers staggered joint press specifications longitudinal seam joints hot pick peace deal, if the transverse joints, longitudinal seam with the same approach. 2, due to changes in the frequency jump overboard point downs asphalt mixing plant, paver adjustment difficulties, jump overboard a spot treatment using artificial paving. 3, stable layer of local irregularities, the first measurement of the elevation, pull a good marking, using artificial light plane, than the design standard level of about 3cm, clean, with a fine stone concrete leveling. Two layers of asphalt pavement type selection using 5cm thick layer of coarse asphalt concrete AC-30Ⅱ type using 4cm thick in the middle grained asphalt concrete AC-20Ⅱ type surface layer using fine 3cm thick asphalt concrete asphalt AC-13Ⅰ road construction, Nanchang asphalt, asphalt road through the tender offer by Nanchang Road, Highway Engineering Co., Ltd. through the asphalt. 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!
