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. Rubber asphalt concrete mixing rubber asphalt concrete mix design and other types of asphalt basically the same. Use Marshall compaction test method to determine the mix asphalt mixture. Rubber asphalt concrete pavement design for this project is open graded gradation. In practical engineering is basically the same with rubber asphalt concrete design process than ordinary asphalt and modified asphalt mixture design process. Rubber asphalt mixture generally do not add slag instead of cement with 1% or lime. Rubber open graded asphalt concrete Whetstone than the average of 7% to 9%. Whetstone specific method than with ordinary asphalt concrete through the same test to determine. Strict control of rubber asphalt and aggregate mixing temperature and exit temperature. (1) before using it if the quality of asphalt rubber check, to determine compliance with the requirements. (2) When the rubber asphalt mixing, the temperature should be controlled at 170 ℃ ~ 185 ℃, but note that not more than 195 ℃. (3) mixing plant control room to be pitch-by-disc printing and all kinds of mineral aggregate amount and mixing temperature, and regularly measuring and mixing plant temperature was checked. (4) mixing time is determined by the trial mix. Must make all aggregate particles all wrapped in complex road asphalt plant asphalt binder, and asphalt mixing uniformity for the degree, the proposed cement admixture is added after the first mixing warehouse and mineral aggregate dry mix 10s, then add the wet mix asphalt rubber 40s . 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 rubber asphalt road asphalt industry to provide customers with a full range of services to 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. Rubber asphalt concrete paving (1) continuous and stable road paving is to improve the flatness of the most important measures. For speed rubber asphalt concrete paving, paver production should be based on mixing plant, machinery and equipment for construction and paving thickness case, paving width, press 1 ~ 3m / min choose to be adjusted, so slow, uniform, uninterrupted to paving. Dining should rotate alternately in batches, should stop shop dine, and strive to achieve every day knock down again. (2) pre-mix uncompacted paving machinery, construction workers allowed to enter the stampede. Under normal circumstances shall the use of artificial renovations. (3) rubber asphalt top layer is made of a non-contact device control paver balance beam thickness. Two paver distance should not exceed 10m, to form a good thermal seams. (4) paver should be adjusted to the best working conditions, a good tune ends augers automatic material level, and to feed the door opening, the chain plate feeder speed and the speed of augers match. Augers in the mix slightly higher than augers 2/3 degrees, so that the front bezel screed mix of highly consistent across the full width of the range, to avoid spreading layer segregation occurs. (5) loose laying thickness detecting whether the provisions to be adjusted at any time. Tanqian screed should be preheated to a predetermined temperature. Paver screed must be spliced ??close asphalt road, there are gaps allowed to prevent the card into the pellets will be paved pull streak. (6) When the paving rain, immediately stop construction, and clear the uncompacted molding mixes. Exposed to rain mix should be discarded, shall not be unloaded into the paver. Asphalt road cost, Nanchang asphalt, asphalt roads paved road pass by Nanchang Road, Highway Engineering Co., Ltd. through the asphalt. Nanchang Road through the asphalt highway engineering Limited (www.dt0791.com) strong, credible, transportation project in Nanchang, Jiangxi collaboration industry has accumulated a large number of loyal customers. The company better work attitude and continuous improvement through innovative ideas will lead the asphalt road and you hand into the brilliant, for a better future!
