Compaction measurement using nearby sensors

A method of compacting a jobsite having a plurality of work areas comprising:

• applying a compaction effort to the plurality of work areas using a compactor;
• receiving an actual compaction state of the work area on which the compactor is located via a compaction state sensor positioned on the compactor;
• receiving at the compactor a plurality of vibration measurements from a plurality of vibration sensors located at a plurality of measuring locations;
• determining a plurality of vibration values from the vibration measurements, each of the plurality of vibration values representing a distance and a direction for each of the plurality of vibration sensors to the compactor;
• and
• generating a compaction state map including each of the plurality of work areas, the compaction state map being based on the plurality of vibration values and the actual compaction state of the work area on which the compactor is located.

A compaction system for a jobsite having a plurality of work areas comprising:

• a first compactor operating on the jobsite, the first compactor having a variable vibratory mechanism providing a first compaction effort to the plurality of work areas;
• a second compactor operating on the jobsite, the second compactor having a variable second vibratory mechanism providing a second compaction effort to the plurality of work areas;
• a plurality of vibration sensors at a plurality of measuring locations;
• and
• a control system in communication with the first compactor, the second compactor, and the plurality of vibration sensors and configured to:
• receive a plurality of first vibration measurements from the plurality of vibration sensors and receive a plurality of second vibration measurements from the plurality of vibration sensors;
• determine a plurality of first vibration values and a plurality of second vibration values based on the first vibration measurements and the second vibration measurements, each of the plurality of first vibration values representing a first distance and a first direction for each of the plurality of vibration sensors to the first compactor, and each of the plurality of second vibration values representing a second distance and a second direction for each of the plurality of vibration sensors to the second compactor;
• and
• determine a projected compaction state for each of the plurality of work areas based on the plurality of first vibration values and the plurality of second vibration values.
