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. Notes 1 Asphalt Pavement. After spraying through the layer of oil should not flow into the bottom must be deep, not constitute an oil film on the outside. 2. In case of high winds or about to rain, you can not spray through the layer of oil. 3. When the temperature is below IO ~ C should not be sprayed through the layer of oil. 4. Shall design a uniform spraying fuel injection quantity, when tainted spill should sprinkle artificial fill. 5. Must be tough to stop and vehicle traffic through layer after spraying oil. 6. Before paving asphalt, still remaining part should not enter the bottom of the asphalt eradicated. 7. Permeable layer should be plenty of tarps and sprinkle soaked, usually less than 24h after top talent paving, but they can not do upper construction for a long time, as soon as possible after construction through the layer of oil spray. 8. After a stable inorganic contact semi-rigid material is sprayed through the bottom layer of oil, if not timely paved surface, and the need to open the traffic, shall be covered by the appropriate spread stone chips or sand, at the moment should be transparent layer of oil to add 10% dosage. With steel drum roller 6-8 regulator again, and speed control. 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 In pouring asphalt pavement, 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.
