ABSTRACT:
Disclosed is a road surface heating vehicle as well as a gas supply system therefor. The vehicle is provided with heating panels and a gas tank. It further comprises a plurality of vaporizers connected in parallel to each other by a gas line and a liquid line. The gas line is connected to the heating panels via its branch lines. The gas and liquid lines are each mounted with a solenoid valve and a pressure adjusting valve. The gas tank is equipped with necessary instruments involved, the vehicle having a body equipped with an operating board containing a microcomputer which automatically makes its control operation based on the use of the associated members, in such a way as to keep the gaseous pressure to fall within a specified range of levels. The system comprises members corresponding to the above-mentioned members constituting the vehicle, including a microcomputer adapted to automatically control the gaseous pressure so that the same may be kept within a specified range of levels.
