Display unit for road machine

A display unit for a road machine, the road machine including a tractor, a hopper installed in front of the tractor to receive a paving material, a conveyor configured to feed the paving material in the hopper to a back side of the tractor, a screw configured to lay and spread the paving material fed by the conveyor behind the tractor, a screed configured to lay and level the paving material laid and spread by the screw behind the screw, and an information obtaining device configured to obtain information on road pavement, the display unit comprising:

• a display;
• and
• processing circuitry configured to predict a future event based on the information on the road pavement obtained by the information obtaining device, and to display information on the event on a road map on the display,
• wherein the processing circuitry is configured to derive a length of an unconstructed pavement to be formed with a transportation vehicle load of the paving material, based on a thickness, a width, and a length of a newly constructed pavement, and to display the derived length on the display.
