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 pavement industry services offer colored asphalt, the main business areas of 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. How large patches of asphalt pavement was durable? Cold patch fed only during the winter look, limited service life, it for months. Have to use hot material, supplemented slotted treatment. But if the foundation does not work, the asphalt pavement can not stand up long. Now the domestic cold-feeding do too messy, the quality varies greatly. Can only say that you do not find the right manufacturers. Quality instability has caused a number of factors. 1. The case pits the grassroots level is not a problem, if there is a problem with the grassroots had nothing useful. 2. cold patch material production process inherent problems, process temperature, following the distribution, and so on. 3. Construction of workers, the workers have no sense of responsibility to see that is not strictly in accordance with the standards of construction. The weather, because cold patch material in the initial stages of dense bad patch after 1-3 days of rain in also affect the quality. Nanchang Road highway Engineering Co., Ltd.

Strength of the material characteristics of the asphalt pitch is determined by temperature conditions. At low temperatures (e.g. winter construction) bitumen in elastic state, at high temperatures (e.g., summer construction) is in a viscous state. This temperature change characteristics of the asphalt directly affect its elastic modulus and shear modulus. Elastic modulus is described by the strain caused by external load asphalt internal stresses. Typically the elastic modulus of asphalt in 1000 N / mm2 (summer) between 9000 N / mm2 (winter) to. Shear modulus describes the shear stress caused by internal asphalt. Material properties of asphalt concrete mix also with the aggregate and asphalt binder and their respective material characteristics. With the ratio of about 95% of the aggregate of bitumen with 5%, but this ratio can do some fine tuning. Binder content and intensity will significantly change the characteristics of the material behavior. Aggregate particles to provide a supportive role for the case of asphalt concrete. It must be used with an appropriate proportion of the particle diameter, a "graded." Graded case should be coordinated with the carrying capacity. When the carrying capacity for good, mixing different size aggregates reach should make aggregate mixed close as possible. Construction should reach the appropriate compression ratio, so that the gap between aggregate asphalt concrete as little as possible. Nanchang Road highway Engineering Co., Ltd.

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, 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 roadbed width of 4.5m or unreasonable depends upon the lot of the road, about 200m every color should be set wrong lane asphalt concrete price, the effective length of the wrong lane of not less than 20m in the wrong lane at both ends should be located not less than 10m transition section. 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 colored asphalt pavement, Gian asphalt, colored asphalt road through the sidewalk 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!
