Characteristics of the asphalt pavement and the common diseases of an asphalt pavement, asphalt pavement cracks. Asphalt road is generally not seen for two years after completion will have a variety of cracks. When the initial cracks in the asphalt pavement performance for basic use did not cause any impact, but it will lead to the invasion of rainwater solid strength of the road to decline. By the same time a lot of the driving process also supercharged work situation undermines the asphalt pavement structure. Cracks form there are many types of asphalt pavement, asphalt pavement cracks from the shape can be divided into three types of horizontal, vertical and mesh. Causes of asphalt pavement cracks roughly three points: 1, asphalt material itself, 2, resulting in decreased roadbed uneven pavement cracking, such as the soft ground would often this phenomenon, 3, reflective cracking of asphalt pavement base. 2, asphalt pavement construction on flawed specifications. Whetstone proportion is generally inaccurate Jiangxi asphalt bitumen production is mainly controlled by the ratio Whetstone Marshall stability to determine the proportion of Whetstone. 3, have a certain impact in general through layers of oil and sticky layer of oil will Whetstone proportion, but in order to ensure good adhesion between the transparent layer of oil and sticky layer of oil, usually through the use of design layer of oil spilled oil with adhesive layer program, but due to sticky layer of oil with transparent layers of oil impact Whetstone proportion is often overlooked, so the larger the proportion of lead Whetstone and the emergence of the phenomenon of weeping. In addition, because the way I face is not flat, there is often a pit package phenomenon, asphalt sticky layer of oil is flowing liquid asphalt mortar price, so in asphalt pavement will often sticky layer of oil aggregation phenomenon, which also contributed to asphalt pavement One of the reasons for weeping.

Principles of asphalt pavement drainage low-grade highway, cross slope asphalt works in general should be around 3% to 4%. When located in a small longitudinal or twisted road ultra relaxation segment, the minimum composite grade of not less than 0.5%. 2. At the intersection of Highway drainage difficult area, road drainage design should meet the technical requirements of driving dynamics and drainage in the discharge port should be set before the intersection. 3. For special parts Longitudinal larger lots, corners inside lane, recess, bridges and other vertical curve ends high embankment to prevent too much water on the roadbed shoulder centralized, slope erosion asphalt, can be partially set up when the water curbs. Set 4. All drainage facilities, in addition to meet the requirements of drainage asphalt pavement construction, should be beneficial in the future to meet the maintenance and repair. 5. In order to reduce the surface water and groundwater across the layers, primary and embankment erosion break, quickly ruled out the water layer between the pavement structure, usually road drainage and pavement drainage system considered. The cost of asphalt road, highway asphalt road price (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.
