Next, it will be rolled, during which it will go through three stages: primary rolling, secondary rolling and final rolling. After all, the joints will be handled and then removed with a cutting machine. Finally, carry out quality inspection and maintenance according to the standards.
Cement mortar or asphalt material can be used to pour the ground. If asphalt concrete pavement is poured, what is the construction technology?
1. What is the construction technology of asphalt concrete pavement?
1, when pouring asphalt concrete pavement, relevant materials need to be prepared in the early stage, and tools for mechanical equipment construction need to be prepared. Only after these preparations are in place can the construction begin. Firstly, the asphalt mixture needs to be transported to the site, and then the setting-out measurement is carried out according to the requirements of road construction.
2. Next, workers need to spread the asphalt evenly, confirm the quality of the next layer, and spread it with two pavers. Workers need later assistance to smooth all materials, and the thickness needs to be determined according to the coefficient.
3. Paving shall be carried out according to the previously controlled lines, and both sides shall be rotated at a uniform speed with an offset press to ensure that the section will not be separated. After paving, the temperature and thickness need to be measured by heating. When problems are found, they should be adjusted in time and recorded.
4, the next rolling, need to go through the initial pressure, pressure and final pressure three stages, wait until the end of the rolling, joint processing, transverse joints and longitudinal joints need to be cleaned up, can be removed with a cutting machine. Finally, in the process of maintenance, quality inspection is needed after maintenance, and acceptance can only be completed if there is no problem.
Second, the matters needing attention in asphalt concrete construction
1. In the construction process, some common quality defects should be avoided, such as mastering the paving thickness and controlling the quality of asphalt mixture from the source.
2. The construction also needs compaction, which is the last working procedure of pavement construction. Only by repeated rolling can we reach a certain thickness, and at the same time control the temperature, which is generally between 1 10~ 120 degrees.
3. After the construction, the pavement must be protected to prevent pollution.
