System and method for determining compaction of work surface

A compactor, comprising:

• a power source configured to power movement of the compactor on a work surface for compaction of the work surface;
• a system for determining the compaction of the work surface, the system comprising:
• a first frame;
• a second frame pivotally coupled to the first frame at an articulated joint, the second frame configured to support the power source;
• a first traction unit operatively coupled to the first frame and configured to compact the work surface via rolling engagement with the work surface;
• a second traction unit operatively coupled to the second frame and configured to propel the second frame over the work surface via rolling engagement with the work surface;
• a force sensor positioned at the articulated joint and configured to measure a force transferred between the first traction unit and the second traction unit through the articulated joint;
• and
• a controller configured to:
• determine, based on the force, a first compaction level of a first region of the work surface in rolling engagement with the first traction unit and a second compaction level of a second region of the work surface in rolling engagement with the second traction unit;
• and
• generate a stiffness map for the work surface based on the first compaction level and the second compaction level,
• wherein the stiffness map enables a user to identify at least one of the first region or the second region to perform work on the at least one of the first region or the second region.
