<p>Compared with the effect of static rollers, vibratory rollers which have the following characteristics:1.Better effect compacted by same quality level of vibratory roller and static effect roller, the tomb with a high base compaction after compaction, good stability.</p>
<P>2.High efficiency of vibrating roller. When the desired degree of compaction is the same, less compaction passes.</P>
<P>3.When compacting asphalt concrete surface layer, due to the vibration effect, make the surface layer of bituminous material can fully penetrate the other aggregate, blend, so the pavement wear resistance, low repair rate.</P>
