The impact energy of the walk behind road roller is large, and there is no strict requirement for the moisture content of the soil. Therefore, the amount of water added to the dry soil can be greatly reduced, and the excessively wet foundation can be drained to accelerate the stability of the soft soil foundation. In addition, with the unique compaction function of the impact bump mill, the back roller can be used as a test roller to detect foundations and layers that have not yet reached the compaction standard or the density is insufficient; the back roller can also be used to crush old cement Concrete pavement and old asphalt pavement
Health.

The walk behind road roller have unique rubbing, turning and mixing effects on the compacted surface. In the rolling process, the upper surface layer will have 100mm thick soil particles and soil blocks rolled up by the rolling angle to play the role of horizontal rubbing and tight penetration and connection between adjacent layers. The loosened surface layer and The new layers will penetrate and mix with each other. After compaction, the integrity is better, and cracks are not easy to occur.

The walk behind road roller low-frequency and large-amplitude impact force on the filler body, and it quickly and successively has periodic effects. The intense shock wave is transmitted to the deep layer below the foundation. It can greatly accelerate the pores for the fragile underground soil layer, especially for the non-cohesive full soil. The loss of water increases the rate of consolidation of soil.
