Investigation of Improved Compaction by Rubber-tire Rollers: Final Report

Report No: 88-R7

Published in 1987

About the report:

The study consisted of a review of the literature and field testing on five projects. The field testing on each project consisted of rolling a conventional section using the contractor's steel-wheel rollers and rolling a test section using a rubber-tire roller as an intermediate roller. The primary benefits found were decreased variability transversely when the rubber-tire roller was used and some improvement in joint density as measured by the nuclear gauge. It was recommended that consideration be given to using a rubber-tire roller where the compaction train does not provide sufficiently dense joints or reasonably uniform compaction.
