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.







Kokosing Construction Company puts the Hamm HD 90 Oscillatory roller through testing on US RT 18 west of Medina, seeing what the roller would do in low mat temperature finish rolling and still get density. The machine was able to obtain density down to a mat temperature of 145 degrees utilizing the oscillatory drum only.
One problem the roller was able to take care of immediately was to eliminate a high longitudinal joint at the left side screed take off spot lateral to a transverse joint by utilizing the oscillatory drum and moving the material away from the joint.
Kokosing Construction purchased two Hamm HD 120 V 78” Oscillatory rollers.





Whether it’s a parking lot, driveway, or tennis court, Ronyak Bros. Paving in Burton, Ohio, has the LeeBoy equipment to do the job. According to Vice-President Mike Briggs, Ronyak, a family-owned paving business since 1939, bought an 8500 Paver last year, bringing them to a total of three 8500 pavers. So far in 2002, Ronyak has added on a 5000 Path Master and a Tack Tank. Ronyak is keeping Jim Hattendorf at McLean very busy.
Ronyak’s new 5000 Path Master makes quick work of golf cart paths. In fact, you can see a Ronyak crew working a golf course on the cover of a future issue of Asphalt Contractor magazine.
Ronyak gets good production with their LeeBoys. One crew put 46,000 tons though one paver in 2001. Briggs expects they’ll put more through in 2002. Briggs adds, “The biggest thing is putting down parking lots. We can push 700 tons at 1-1/4 inches per day on 70,000 to 80,000 square feet, because the LeeBoy’s can push the trucks easily. It’s then that you can get production. That’s the key—getting production”
