Shelly and Sands uses the oscillatory technology from Hamm Compaction to help themselves out of a tough application on US RT 23 in Chillicothe, Ohio. The job requirements were two asphalt 12mm lifts over joint repaired concrete that carried smoothness and density requirements. This is a problem for all contractors in Ohio (see Flexible Pavements article link) http://www.flexiblepavements.org/images/techbullcrackseal.pdf
Traditional vibratory rollers were first used to compact the material. Joint repair bumps would occur so it was determined by Ed Morrison of Shelly and Sands QC department to try using the new Hamm oscillatory roller technology along with old technology of the pneumatic tired roller. Both worked very well in getting rid of the bump reoccurrence.
