| 1. A compaction system, comprising:
a first and second array of compaction elements supported by an underside of a motorized vehicle adapted to traverse a degraded
surface;
a plurality of pavement degradation elements supported by the underside that rotate about an axis substantially normal to
the degraded surface;
a sensor assembly supported by the motorized vehicle, disposed intermediate the first and second array of compaction elements,
and in electrical communication with a controller;
the sensor assembly also being adapted to sense a characteristic of an at least partially compacted surface formed after the
first array of compacting elements applies a first compaction pressure to the degraded surface;
the controller being in electrical communication with the second array of compaction elements and comprising an input field
for a second compaction pressure;
wherein the sensor assembly is adapted to input the second compaction pressure into the field and the controller is adapted
to adjust the second array of compaction elements to apply the second compaction pressure to the at least partially compacted
surface.
