Does the speed of the XCMG Road Roller Compactor affect the compaction effect?

The working speed has a great influence on the compaction degree of vibratory compaction. The test shows that the working speed of the small road roller is closely related to the compaction characteristics of the soil or the material to be compacted, the thickness of the compacted layer, the compaction work of the road roller, the construction technical requirements and the operation efficiency. and other factors. For cohesive soil, the working speed should not be too high due to the obvious deformation hysteresis; for the initial pressure of the layup, due to the large deformation of the layup and the large rolling resistance of the road roller, the working speed should not be too fast; Basically dense, in order to improve the surface smoothness, the working speed can be increased appropriately.

It has also been proved by practice that if the rolling speed is too high, there will be phenomena such as shifting, transverse cracks or ripples, and if the rolling speed is too low, the paving and compaction process will be interrupted and the compaction effect will be affected. Therefore, when selecting the rolling speed of small and medium-sized road rollers, the rolling speed should be increased as much as possible under the premise of ensuring the compaction quality, so as to reduce the number of rolling times and improve work efficiency.
