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 asphalt highway engineering, asphalt industry to provide comprehensive services to major business areas 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. Where appropriate thinning asphalt surface layer thickness for the following four main considerations. 1, the carrying capacity of semi-rigid base asphalt pavement structure can be semi-rigid material layer (base and subbase) to bear, without thickening the surface layer to increase the carrying capacity. 2, improving asphalt pavement performance than using thick asphalt surface, but with a high-quality asphalt. 3, crack asphalt surface not only reflective crack under normal working conditions, most of the asphalt surface layer itself temperature shrinkage cracks. 4, generally thick asphalt surface rutting easily lead generation. Meanwhile asphalt road asphalt pavement should strengthen waterproof design, selection of a reasonable base and subbase structure. 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 road maintenance, 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 Bidding asphalt road network, especially thinking horizontal force, can be reached zero. The total thickness of the asphalt layer 5 MPa Add to add thickness and strength under the deck, and its appearance are added tensile stress, 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 0 ~ 10 cm within the larger shear stress, without thinking horizontal force, the maximum shear stress with the added thickness of asphalt added, thus adding asphalt surface The total thickness of the 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.
