✦ Synopsis

This paper describes a waste heat recovery apparatus that utilizes the truck exhaust gas to heat the bitumen used in road maintenance by means of heat transfer oil as working fluid when en route to road maintenance destination. This apparatus is composed of an oil heater, bitumen tank, oil circulation system and some auxiliary instruments. By measuring temperatures and flow rate of exhaust gas, it is concluded from the calculation and analysis that this waste heat recovery apparatus is feasible and can save much conventional energy and decrease environmental pollution.
