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 in Jiangxi | Jiangxi asphalt concrete mixing stations), factory mixing plant was established in 2009 , is a professional road asphalt industry chain of integrated companies, providing customers with a full range of asphalt industry services, business areas mainly for asphalt pavement construction, spraying emulsified asphalt, marketing 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 layer of asphalt pavement surface layer of the composite structure of the asphalt surface layer stress analysis, we can draw the following conclusion: ① underlying asphalt surface layer to the rigid outer layer of asphalt composite pavement presents a greater tensile stress , especially ponder horizontal force, can be reached 0. The total thickness of 5 MPa asphalt layer is added, adding the next layer thickness and strength of commitment, its appearance tensile stress are added, thus, the outer surface structure pattern should have excellent tensile function. ② because bearing layer is successively reinforced concrete, asphalt surface showed greater shear stress in the 0 ~ 10 cm, do not think the level of force when the maximum shear stress with added asphalt layer thickness add asphalt, asphalt parking lot and therefore pavement, adding a total thickness of asphalt surface not much use to reduce rutting. Thus, the rigidity of the bottom layer of asphalt layer should have excellent anti-rutting function. And asphalt surface layer thickness should not be too thick, and advocates 8 ~ 12 cm. ③ In view of the series of reinforced concrete asphalt surface layer of the composite structure of asphalt pavement surface should accept tougher environmental stresses, therefore, advocated the selection function better road asphalt type, the choice of the outer layer of modified asphalt SMA, in the face Selection asphalt layer skeleton dense asphalt mixture.

Strength of the material properties of asphalt pitch is determined by the temperature conditions. At low temperatures (for example, winter construction) bitumen in an elastic state, at high temperatures (eg summer construction) is in a viscous state. The temperature of asphalt directly affect its elastic modulus and shear modulus. Elastic modulus is described by the strain caused by external load asphalt internal stress. 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. The material properties of the asphalt concrete is also related with the ratio of asphalt binder and aggregate materials and their respective characteristics. With the ratio of about 95% of the aggregate of bitumen with 5%, though this can do some fine-tuning. Binder content and intensity will greatly change the material behavior characteristics. Aggregate particles are supported by the case of asphalt concrete. It must be used with an appropriate particle size diameter ratio, a "graded." Grading case be coordinated with the bearing capacity. For when good carrying capacity, mixing different size aggregates reached, should make the aggregate after mixing closely as possible. Construction also achieve an appropriate compression ratio, so that the gap between aggregate asphalt concrete as little as possible. Nanchang Road highway Engineering Co., Ltd.

Asphalt pavement construction work site safety tips asphalt pavement sweeping security key 1, road sweeping road to be completely closed to all vehicular traffic stop, prevent vehicle damage. 2, road cleaning operations should downwind side hair asphalt pavement crack repair, stop outlet for people. 3, hairdryer site refueling, to pay attention to the fire. 4, giving the job polyester fiberglass industry workers, it is necessary to leather overglove. First, gravel spreader job security key 1, spreading gravel spreader speed for a stable, does not allow the shift in the spreading process. 2, spreader in the job, coupled with a rigid dump truck, while spreading, while pouring; also interrupted traffic and spreading until the dump finished unloading the car then spreading colored asphalt pavement price, to prevent spreading the bump dump truck machine. 3, to prevent the spreader own remote handling. 4, the spreader in the job process to settle alert personnel, pay attention to pedestrians and vehicles, to prevent bump and gravel flying wounding trouble.
