Abstract: A system for determining a state of compaction of a work material during a compaction operation includes: a roller associated with a machine for engaging and compacting the work material; a power loss sensor for generating power loss signals indicative of a power loss of the machine; a speed sensor for generating speed signals indicative of a speed of the machine; at least one deflectable tire associated with the machine for engaging the work material, the at least one deflectable tire having tire characteristic data associated therewith; a tire pressure sensor for generating tire pressure signals indicative of a tire pressure of the at least one deflectable tire; and a controller that: receives the power loss signals from the power loss sensor, receives the speed signals from the speed sensor, and receives at least one of the tire pressure signals from the tire pressure sensor and the tire characteristic data.

Abstract: Systems, methods, and computer program products can wirelessly receive moisture data outputted from one or more wireless moisture sensors at least partially embedded in a material to be compacted by a compaction machine; determine, based on the moisture data from the one or more wireless moisture sensors, whether water needs to be added to the material at each of the one or more wireless moisture sensors; and output signaling to direct a water truck to provide water to the portion or portions of the material determined to need water.
