Abstract (en)

[origin: JP2017214820A] PROBLEM TO BE SOLVED: To provide a soil compactor for rolling compaction of asphalt applied on a ground for roller compaction of the ground.SOLUTION: A soil compactor includes: at least two vibration compaction rollers 14, 16 rotatable respectively around a roller rotation axis; vibration generating structures 22, 24 for generating vibratory motion of the vibration compaction rollers 14, 16, for each of the vibration compaction rollers 14, 16; vibration detection structures 38, 54 for preparing a vibration value indicating the vibratory motion of each of the vibration compaction rollers 14, 16, for each of the vibration compaction rollers 14, 16; and control structures 36, 56 for controlling at least either of the vibration generating structures 22, 24 based on the vibration value prepared for the vibration compaction rollers 14, 16, so that the vibratory motion of the vibration compaction rollers 14, 16 have predetermined mutual phase displacement.SELECTED DRAWING: Figure 2
