  • Machine alert when stopping on hot asphalt
    Patent number: 9367042
    Abstract: An alert system in equipment used in an asphalt paving environment, such as a compactor, signals an operator when the equipment is stopped on hot asphalt, potentially over-compacting the area where the equipment is located. The alert system includes a surface temperature sensor so that the alert is only activated when there is a risk of over-compaction because the asphalt is still above a threshold temperature. The alert system may also include a timer so that the operator is not signaled during routine stopping associated with changing direction during compacting operations.
