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. The basic principle of the main component of the bitumen emulsion is emulsified asphalt equipment bitumen, water, emulsifier and stabilizer. Almost various grade petroleum asphalt, may be used in the preparation of a bitumen emulsion. By high speed agitation or mechanical shearing emulsification, the asphalt broken into fine particles, dispersed in an aqueous emulsifier effect of surface-active substances in a homogeneous dispersion is obtained limb. Asphalt emulsion particle diameter substantially within the range of 1-5μm. The basic role of the emulsifier is to reduce the surface tension. Which is characterized by molecules having a water-soluble (hydrophilic) polar group and an oil soluble (hydrophobic) of non-polar groups. A water system in the asphalt emulsifier molecules move in between bitumen and water interface, which cherish the water molecules adsorbed on the surface of the asphalt group and make it with a charge, while the hydrophilic groups into the aqueous phase. Pitch particles thereby link up with water, to reduce the interfacial tension between the two. Meanwhile, since the pitch with the same electric charge particles repel each other, prevent mutual cohesion between them, thus making the bitumen emulsion can be kept uniform and stable in a certain period.

Characteristics of the asphalt pavement and the common diseases of an asphalt pavement, asphalt pavement cracks. Asphalt road is generally not seen for two years after completion will have a variety of cracks. When the initial cracks in the asphalt pavement performance for basic use did not cause any impact, but it will lead to the invasion of rainwater solid strength of the road to decline. By the same time a lot of the driving process also supercharged work situation undermines the asphalt pavement structure. Cracks form there are many types of asphalt pavement, asphalt pavement cracks from the shape can be divided into three types of horizontal, vertical and mesh. Causes of asphalt pavement cracks roughly three points: 1, asphalt material itself, 2, resulting in decreased roadbed uneven pavement cracking, such as the soft ground would often this phenomenon, 3, reflective cracking of asphalt pavement base. 2, asphalt pavement construction on flawed specifications. Whetstone proportion of bitumen is generally inaccurate, Whetstone proportion is mainly controlled by the Marshall stability to determine the proportion of Whetstone. 3, generally through the layer of oil and sticky layer of oil would have a certain impact Whetstone proportion asphalt road reconstruction, but in order to ensure good adhesion between the transparent layer of oil and sticky layer of oil, usually through the use of spilled oil layer with adhesive layer design of oil, but because of sticky layer of oil with transparent layers of oil impact Whetstone often overlooked proportion of bitumen road maintenance, so much money paved asphalt road, leading to relatively large proportion Whetstone and the emergence of the phenomenon of weeping. In addition, because the way I face is not flat, there is often a pit package phenomenon, asphalt sticky layer of oil is a liquid flow, so in asphalt pavement will often sticky layer of oil aggregation phenomenon, which also contributed to asphalt pavement weeping one of the reasons. Asphalt road maintenance, Gian asphalt road through the asphalt road how much money is provided by the 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!
