In spring construction, how to achieve orderly and efficient compaction of pavement with small rollers?

When working on a new road, compaction shall be carried out from the middle to the outside. During operation, the distance from the edge of subgrade shall not be less than 0.5m. The longitudinal gradient of the working part shall not exceed the climbing capacity of the roller, and the transverse gradient shall not be greater than 20. The front and rear direction of the roller shall be changed after the roller stops, and the reverse clutch shall not be used for braking. After separating the main clutch, adjust the reversing clutch, starting clutch and brake. When compacting soft subgrade soil, it should be rolled 2 to 3 times without vibration, and then vibrated. With the rapid development of expressway, the development of road construction machinery has also been promoted. In this context, one-ton, one-and-a-half and two-ton rollers have also developed rapidly. Many construction sites are using this powerful and fully functional machine. In the face of differences on whether the hydraulic one-ton roller is easy to use, we might as well take a look at the actual use effect.

The hydraulic system of the full-hydraulic one-ton roller has been fully upgraded, and it has faster speed, stronger climbing ability and long-term operation even in harsh conditions. Its own vibration frequency is 70HZ and its excitation force is 2.7t, which ensures better compaction effect. 2. Steel drum is the main working tool of the hydraulic one-ton drum. The quality of steel wheel is crucial to the compaction effect. Therefore, not only steel wheels should be strengthened, but also steel wheels with 700mm wheels and 500mm diameter wheels should be used. At the same time, the front frame side plate, frame plate, steel wheel and rear frame of the hydraulic one-ton roller have been enhanced to improve their wear resistance and adapt to more complex working conditions. 3. Full-hydraulic one-ton roller adopts full-hydraulic drive and stepless speed change. The front and rear reversing operation is simple and convenient, and there is no need to step on the clutch, shift, brake, slowly release the clutch and other actions, which greatly reduces the labor intensity of the driver and enhances its convenience. 4. The reason why the performance of the full-hydraulic one-ton roller is so superior is because of its high-end configuration. Among the five key components of the full-hydraulic one-ton roller, domestic brand engines, imported brand hydraulic pumps, imported brand hydraulic motors, and hydraulic valve blocks all adopt large brand products, with excellent quality!
