Asphalt pavement compaction links generally include the following aspects: the road surface of the initial pressure, the road surface of the complex pressure and the final pressure. First, the initial pressure of the road. The initial pressure is the primary link of road compaction, this link is generally carried out directly after the mixture paving, this time the temperature is higher, generally the first vibration vibrator squeeze,Practical discount sales paver vibration after the closure of the vibration device, the slow Slow rolling 2-3 times, the initial pressure of the link temperature is generally maintained at 110-140 degrees Celsius. So, as long as the tonnage of relatively small compaction equipment can play a very good effect.
Under normal circumstances, the use of 6-8 tonnage double drum roller can be. In the process of rolling, the drive wheel to move forward at uniform, when the time to move back in accordance with the movement of the grinding lead. When the initial pressure in the asphalt pavement, after the initial pressure to have the relevant technical staff of the road surface roughness,Good quality integrated maintenance vehicle manufacturer road arch to check, once the problem should be corrected immediately. If the road rolling phenomenon occurs during the passage of time, this time can wait until the temperature becomes low after rolling, such as the emergence of transverse cracks, should check the cause and take corrective measures in a timely manner. Second, the road pressure. Compaction of the road is an important stage of compaction, through the re-pressure is mainly to ensure the stability of the asphalt mixture molding, so that the complex pressure is generally high-temperature part of the process and followed immediately after the initial pressure process. Under normal circumstances,pavement on concrete machine the road surface of the complex pressure link temperature should be maintained at 120-130 degrees Celsius.
Usually by two-wheel vibratory road roller, in the rolling method can be used with the initial pressure of the same method, the number of rolling should be more than 6 times, the only way to ensure the stability of the road and strong; Final pressure of asphalt pavement. Final pressure is the last step to eliminate traces, defects, and to ensure a smooth surface finish. As the final pressure to eliminate the re-pressure in the course of the surface layer remains uneven, but also to ensure the smoothness of the road, therefore, the asphalt mixture also need high but not too high rolling temperature end rolling. The temperature at the end of the final pressure should be greater than 90 degrees Celsius. In the final part of the road pressure,Top Rated Portable Heat Lance the final pressure often used static double-wheel road roller and should be immediately after the re-pressure, rolling times for 2 to 3 times. Through the road surface pressure, re-pressure, the final pressure of the combination of three aspects, thus ensuring the asphalt pavement smooth, stable and thick, and improve the overall quality of the asphalt pavement. Construction of Spreading Road Surface.
