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 services bituminous asphalt industry, operating mainly in the field of 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. Asphalt concrete pavement construction program complement an asphalt concrete paving: 1, based on cross-sectional width of the roadbed and paver functions, this time laying asphalt concrete paving construction using demi, demi Paving layers staggered joint press specifications coal tar pitch, longitudinal seam joints hot pick peace deal, if the transverse joints, longitudinal seam with the same approach. 2, due to the frequent ups and downs point jump overboard, pavers adjustment difficulties, jump overboard a spot treatment using artificial paving. 3, stable layer of local irregularities, the first measurement of the elevation, pull a good marking, using artificial light plane, than the design standard level of about 3cm, clean, with a fine stone concrete leveling. Two layers of asphalt pavement type selection using 5cm thick layer of coarse asphalt concrete AC-30Ⅱ type using 4cm thick in the middle grained asphalt concrete AC-20Ⅱ type surface layer using fine 3cm thick asphalt concrete AC-13Ⅰ type 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 , is a professional road asphalt chain of integrated companies warm mix asphalt, 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 rental other 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 No. 70 asphalt concrete, asphalt concrete, like the same way as ordinary ratio determined by experiments. 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 complex 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. Asphalt mortar _ _ Nanchang Road asphalt hot mix asphalt 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!
