Development and Evaluation of Relative Compaction Specifications Using Roller-Based Measurements
Earthwork quality control/quality assurance specifications are currently being developed and implemented with continuous compaction control (CCC) and intelligent compaction (IC) rollers. This paper presents and explores two methods of using CCC/IC data based on a relative compaction approach. The first method examines the relative change in roller-measured mean compaction level between passes while the second method examines relative changes spatially. The relative compaction methods were implemented on a test site. The relative compaction methods were found to provide improvement over current methods due to their ability to quantitatively assess 100% of the compacted area while decreasing time and cost during the construction process.
