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.

Winter construction of asphalt due to low winter temperatures measures in order to ensure the quality of asphalt pavement construction, during construction, to take appropriate measures according to specification, good winter protection construction, according to the following requirements to guide the construction: a construction unit should seriously develop targeted Winter construction program, supervision units to develop special supervision programs, construction units should be strictly according to the construction plan approval and supervision units Winter conduct tests, and after construction. 2 effectively improve the degree of attention to the construction quality of winter, the full implementation of quality management responsibility at all levels. Participation three main parties should strict liability, in strict accordance with the design and construction and acceptance of the relevant state inspection, construction units to strengthen the main responsibility of the parties participating in the construction project of the organization, coordination and supervision. 4 for a variety of situations that may arise, develop several sets of corresponding construction plans. 5 Strengthening the construction site contact with the asphalt road asphalt mixing plant modification, hand command, unified, so that quantitative, timing, car tissue supply, timely supply. 6 requires a variety of mechanical equipment and the site must have backup equipment. The first seven grassroots response surface construction inspection, grassroots should meet the quality requirements, and requirements before spreading to cover the lower bearing layer insulation, moisture, so that its surface is dry, no freezing. Asphalt paving job without the temperature is below 8 5 ℃. Nanchang Road highway Engineering Co., Ltd.

Asphalt loader when the job safety precautions should be observed before the start 1. whether the machine around obstacles and pedestrians, the bucket lifting off the ground about 500 mm, before they start honking. Driving, depending on the road conditions should be chosen high gear, while driving is prohibited bucket lift and flip action; 2. the job should be selected low gear. When walking, try to avoid lifting the bucket too. Should be based on different soil, different shovel way, try to be inserted from the front to prevent the bucket unilateral force. In loose uneven job site, can lift lever in the float position, the bucket grading; 3. traveling road shall be flat, not a job on the inclination exceeds the venue, transport distance should not be too large. Residential asphalt road construction, the bucket should be kept in a bucket full of transporting low; 4. loose uneven field operations, can be placed in a floating position shovel arm, bucket smooth manner. Propulsion resistance is too large, may slightly enhance the shovel arm asphalt, front bucket should be inserted into the low-loader, bucket prevent unilateral force; 5. to unload land transport vehicles should slow the bucket should be in the right height, before the turn and can not return the car crash; 6. should always pay attention to the mechanical operation of the sound and found different response immediately stopped and troubleshooting. When the engine is not running when you need traction, keep each steering cylinder can move freely; 7. shovel (material), it may not be used to increase the throttle, the bucket-speed dash into the soil (material) heap way loading, Application of low-end is inserted into the bucket parallel to the ground, then dropped the shovel arm, along the ground and gradually increase the engine speed forward driving, while volumes earth (material) in order to reduce the resistance encountered by the bucket road asphalt modification, colored asphalt road through road (certified), provided by the Nanchang Road Yingtan asphalt through the asphalt highway engineering Limited. Nanchang Road through the asphalt highway engineering Limited (www.dt0791.com) is a leader in Nanchang, Jiangxi, transportation cooperation projects over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In the asphalt road leading through the staff warmly welcome all inquiries negotiations to create asphalt road through a better future.
