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 district asphalt roads, 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? Feeding only mended cold in the winter, a limited service life of asphalt road, also a few 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 itself, the problems of asphalt road construction, 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.
