Erie Blacktop Hamm HD120V



Erie Blacktop put their new Hamm HD 120 V oscillatory roller to work on a 1-1/4” non compacted 9.5mm Super Pave surface course job. This mix was tough to compact utilizing traditional vibratory high frequency machines in the breakdown mode. It was decided by McLean Company representatives with Chris Schaeffer of Erie Blacktop permission to try using the Oscillatory roller in breakdown mode using just the Oscillatory drum only. The density then jumped up to an acceptable number after a 4000 vpm machine would not get the density numbers required in the breakdown mode.
