1. A system for controlling a paving system, comprising:

  • a plurality of supply machines, each supply machine including;

    a first ground engaging drive mechanism to propel the supply machine;

    a material transport unit in which a load of paving material may be transported;

    a first position sensor for determining a position of the supply machine;

    a first wireless communications system on the supply machine; and

    a first controller configured to;

    determine the position of the supply machine; and

    transmit supply machine position signals indicative of the position of the supply machine; and

    a paving machine including;

    a second ground engaging drive mechanism mover to propel the paving machine;

    a material receiving unit for receiving paving material from the supply machine;

    a material application system for applying the paving material to a work surface;

    a second sensor for determining a rate at which the paving material is being applied to the work surface;

    a second wireless communications system on the paving machine; and

    a second controller configured to;

    determine the rate at which the paving material is being applied to the work surface; and

    a temperature sensor associated with one of the plurality of supply machines and the paving machine for determining a temperature of paving material delivered to the paving machine by one of the supply machines; and

    a plant for producing a batch of paving material including;

    a holding location at which the batch of paving material is held;

    a batch temperature sensor for determining a batch temperature of the batch of paving material;

    a third wireless communications system at the plant; and

    a third controller configured to;

    determine the batch temperature;

    receive signals indicative of the position of each supply machine;

    receive signals indicative of the temperature of paving material delivered to the paving machine; and

    generate command signals to adjust the batch temperature based upon the position of each supply machine and the temperature of paving material delivered to the paving machine.
