PROBLEM TO BE SOLVED: To provide a macadam type vibration roller capable of extensively and efficiently rolling a road surface by overcoming respective problems belonging to a tandem roller. SOLUTION: This macadam type vibration roller R is equipped with: right and left rolls which are arranged in a state of being paired on right and left sides while sandwiching a vehicle body 1 in between; and a central roll which is arranged between the right and left rolls in a front view. Vibration mechanisms are provided in the right, left and central rolls, and vibrated, respectively, so as to make all the rolls simultaneously vibratable. Axle loads, per unit width dimension, of the respective rolls are approximately equal to one another; and the frequencies and amplitudes of the respective rolls are approximately equal to one another.
