Abstract
Accurately determining the compaction state of a base material during the compaction process is a recognized problem in the construction industry. The present invention recognizes that the compaction state of the base material can be determined by ascertaining the effective roller radius of the compactor. In other words, in the case of powered compactors, the effective roller radius will asymptotically approach the actual roller radius as the base material changes from a soft un-compacted condition to a hard compacted state. Monitoring compaction state via indicative of an effective roller radius can be used alone as a means of determining compaction state in real time, or can be leveraged and combined with other independent means of monitoring the compaction state to a symbiotic affect in more accurately determining compaction state.
