A system for determining compaction of a work surface. The system includes a first frame, and a second frame pivotally coupled to the first frame at an articulated joint. The system includes a first traction unit operatively coupled to the first frame and configured to compact the work surface and a second traction unit operatively coupled to the second frame and configured to propel the second frame over the work surface. The system includes a force sensor positioned at the articulated joint and configured to measure a force transferred between the first frame and the second frame. The system includes 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.

A system for a compactor includes one or more first sensors, one or more second sensors, and a controller including one or more memories and one or more processors. The processors are configured to receive, from the first sensors, one or more first signals indicative of a first amplitude of vibration of a first vibration system of the compactor, receive, from the second sensors, one or more second signals indicative of a second amplitude of vibration of a second vibration system of the compactor, determine if a difference between the first amplitude of vibration and the second amplitude of vibration is greater than a predetermined threshold value stored in the memories, and generate an output signal if a difference between the first amplitude of vibration and the second amplitude of vibration is greater than the predetermined threshold value.

A system for determining a state of compaction of a work material during a compaction operation: 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; and a controller that: receives an actual drive power target value, receives the power loss signals from the power loss sensor, receives the speed signals from the speed sensor, determines a gross power of the machine based on the power loss signals, determines a friction loss power of the machine based on the speed signals, and determines an actual drive power of the machine based on the gross power and the friction loss power, the actual drive power corresponding to the state of compaction of the work material.

A system for controlling compaction operations may receive, from one or more sensors associated with a machine performing compaction operations on earthen materials, sensor data indicating a compaction level. The system may determine, during the compaction operations, a compaction level of the earthen materials based on the received sensor data. Further, the system may receive, via an input device on the machine, a first user input indicating an acceptable compaction range. The system may display, via a gauge on a display screen, the determined compaction level and the acceptable compaction range. Further, the system may receive a second user input associated with at least one operating parameter of the machine in response to the determined compaction level being outside the acceptable compaction range. The system may adjust the at least one operating parameter based on the received second user input.

A system for indicating a non-ideal condition of a drum of a compactor includes a sensor coupled to the drum of the compactor that generates a signal indicative of a current amplitude of vibration of the drum. The system also includes a controller that includes one or more memories and one or more processors. The one or more processors receive, from the sensor, the signal indicative of the current amplitude of vibration of the drum, compare the current amplitude of vibration with a nominal range for amplitude of vibration of the drum, determine if the current amplitude of vibration is outside the nominal range for amplitude of vibration, and generate an output signal if the current amplitude of vibration is outside the nominal range for amplitude of vibration. The output signal is indicative of the non-ideal condition of the drum of the compactor.
