Abstract
In a first embodiment, a method and apparatus for determining compaction performance of a material by a compactor having a known compaction width. The method and apparatus includes determining a lift thickness of the material, determining a rolling resistance of the compactor, determining a level of compactive energy delivered to the material as a function of the compaction width, the lift thickness and the rolling resistance, and determining the compaction performance of the material as a function of the compactive energy. In a second embodiment, a method and apparatus for determining compaction performance of a material by a compactor. The method and apparatus includes determining a ground speed of the compactor, determining a rolling resistance of the compactor, determining a propelling power of the compactor as a function of the ground speed and the rolling resistance, and determining the compaction performance of the material as a function of the propelling power of the compactor.
