Abstract: A worksite management system directs one or more mobile machines to enhance the compaction of the terrain surface about a worksite. One or more local topography detectors that may be located on a non-compactor mobile machine measures the state of compaction of the local topography proximate to the mobile machine. An electronic controller that may be onboard the mobile machine detects if the detected state of compaction corresponds to a first topography area associated with a greater state of compaction and, if so, directs the mobile machine to a second topography area associated with a lesser state of compaction.

Abstract: A controller may obtain compaction data indicating one or more of a vibration amplitude or a vibration frequency used for a compaction drum of the compactor machine at a plurality of locations of the compactor machine on a paving material mat.

The controller may cause the compactor machine to perform a compacting operation at an area of the paving material mat based on the compaction energies.
