Early this month, on a field trip with Mike Logan of tho Bureau of Public Roads and R. D. Medley, Asst. Director of Design, I had an opportunity to look over a project in Ohio where a vibratory method of compaction was being used in tho construction of a macadam base course, This type of compaction is relatively new, it having been tried for the first time in this country about four years ago, To my knowledge, the first published report on the procedure was made in the Proceedings of the Highway Research Board, Volume 27, page 148, 1947.
This report, by Messrs. Allen and Linzell, entitled "Use of Vibration In Placing Screenings In Macadam Bases" described the two types of machines which were tried experimentally, and illustrated some of the results.
