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 asphalt emulsifier factory, in the hard work, the principle of sincere and trustworthy, asphalt pavement construction industry has been recognized by the owners and customers. 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. (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. Through a series of reinforced concrete bottom of the asphalt surface layer of the composite structure of asphalt pavement surface layer stress analysis, the following conclusions can be drawn: ① For rigid underlying asphalt surface appearance of asphalt pavement layer composite exhibits a large tensile stress , especially thinking horizontal force asphalt repair, can be reached zero. The total thickness of the asphalt layer, add 5 MPa, under the order of the thickness and strength of adding asphalt prices, its appearance tensile stress are added, and thus, the outer surface structure type should have excellent tensile function. ② because bearing layer is a series of reinforced concrete, asphalt surface showed a greater shear stress within 0 ~ 10 cm, without thinking horizontal force, the maximum shear stress with the added thickness of asphalt added, thus asphalt, asphalt add The total thickness of the surface layer does not have much use for the reduction of the rut. Thus, the rigidity of the bottom layer of asphalt on the rutting resistance should have an outstanding feature. And asphalt surface layer thickness should not be too thick, and advocates 8 ~ 12 cm. Given a series of reinforced concrete ③ asphalt surface layer of the composite structure of asphalt pavement surface should accept more stringent environmental stress, therefore, advocated the selection function better road asphalt type, choose the outer layer of modified asphalt SMA, in the face selection of modified asphalt layer skeleton dense asphalt mixture.
