Asphalt pavement with asphalt concrete road which is not the same as asphalt pavement is sticky so easy to crack when it is pressed, but carries little pressure, concrete pavement is hard ah! If the crack is difficult to do ah! It is generally asphalt concrete pavement will be used to pour a little crack in the cracks, you can stick ah! Can also be waterproof. Cement pavement are rigid pavement, grass-roots requirements are relatively high, if the grass-roots problems, it is prone to breaking boards Frothing phenomenon, generally in the lateral groove machine will use the groove to increase the friction when the vehicle travels pavement are flexible road surface to withstand most power, but now more and more new material, such as SMA, drainage effect is much better than before, the high temperature stability is also a lot stronger Nanchang Road highway Engineering Co., Ltd. (Nanchang asphalt |. Jiangxi asphalt | Nanchang Asphalt Pavement | 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 industry chain integrated the principle of the 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, sincerity and trustworthiness, in the asphalt road construction industry has been recognized by the owners and customers. Rubber asphalt project rolling molding (1) asphalt compaction is to ensure the quality of the asphalt surface important part, you should choose the right combination of rollers and rolling steps. To ensure compaction and flatness, initial pressure should be at a higher temperature after paving a timely manner. To prevent adhesion of rubber asphalt rubber tires, rubber asphalt concrete should not use rubber tire roller. Usually with 3-5 sets initial pressure drum compactor followed paver rolling vibration. (2) rubber asphalt compaction process is divided into the initial pressure, re-pressed and final pressure. (3) should be slowly and evenly roller speed rolling asphalt pavement, rolling speed roller suitable recommendations in Table 3 selection. Roller rolling speed (km / h) the initial pressure roller type complex pressure final pressure static load drum compactor 2 ~ 3--3 drum vibratory roller 2 to 6 ~ 43 ~ 5 - (4) In order to avoid rolling when Push mixture to produce pro package, when the wheels rolling toward the paver; rolling route and should not abruptly change direction; rollers start, stop must slow amble, are not allowed to brake. Rollers should turn back at the same cross section. (5) The initial pressure should be followed pavers were rolling progressive, with the paver. Complex pressure, the final pressure should distinguish between paragraphs, setting up clear signs, easy recognizable drivers. Shop for loose thickness, rolling sequence, roller combination, rolled several times, rolling speed and rolling temperature should be set up to manage and inspect the gang, so do not drain surface pressure nor overpressure. (6) the degree of compaction of rubber asphalt concrete required to achieve at least 96% of the requirements. 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 cold asphalt paved in asphalt pavement construction industry has been recognized by the owners and customers. Require an asphalt material, asphalt: asphalt beneath layers of high-quality Class A asphalt road, the top layer of high quality asphalt, the technical requirements should be consistent with the requirements specifications and design documents. Asphalt entire inspection by XX project department agreed to entrust a qualified test units, construction units and supervision units according to the construction site laboratory technical specifications for asphalt scene detection and retention samples were seized. 2, coarse aggregate: the stone hard, clean, free of weathered particles, nearly cubic particles of gravel, particle size greater than 2.36mm (SMS top layer particle size greater than 4.75mm), the following layer should be used alkaline limestone stone or the use of emulsified asphalt adhesion good stone company, the top layer is made of basalt gravel should be chosen crusher rolling gravel, and strictly control the elongated flat particle content, in order to ensure the quality of coarse aggregate. Adhesion between aggregate and asphalt must meet regulatory requirements, take the top layer of anti-stripping agent before blending measure adhesion between the coarse aggregate and asphalt shall not be less than four. Aggregate quality should be the source, send someone stationed in aggregate processing plants. Fine Aggregate: A hard, clean, clean, no weathering, no impurities and artificial rolling properly graded meters of sand, not using scraps mountain farm, which should meet the quality requirements specified in the following table: 4, packing: alkaline limestone stone should be adopted by the resulting ore milled. Slag must be dry, clean, slag quality and technical requirements should meet the specifications and design documents, entering filler required for testing. Powder mixing machine can not be used recycled asphalt mixing in order to ensure the quality of the asphalt surface layer. Asphalt paving, asphalt road through road works (certified), provided by the Nanchang Road Yingtan asphalt through the asphalt highway engineering Limited.
