Claims

[Scope of utility model registration request]

In a paving vehicle that performs paving work by sending paving material stored in a hopper of the vehicle to a leveling device via a feeder while the vehicle is running, starting and stopping the paving vehicle from outside the vehicle a radio controller that controls the feeder, a pavement control mechanism that detects the presence or absence of paving material on the feeder and controls the start and stop of the paving vehicle, and an automatic system that causes the vehicle to travel along a travel reference line set on the road surface. A paving work vehicle characterized by being equipped with a steering mechanism.
