THERMOSTATICALLY CONTROLLED ASPHALT HEATER FOR A MOBILE PAVEMENT PATCHING VEHICLE

摘要

ABSTRACT ‘THERMOSTATICALLY CONTROLLED ASPHALT HEATER FOR A MOBILE PAVEMENT PATCHING VEHICLE’ A system for maintaining the temperature of the contents of an asphalt storage hopper mounted to a mobile pavement repair vehicle. The thermostatic control system directs a flow controller to direct exhaust gases from the engine of the vehicle either to the atmosphere or to a heat exchanger within the asphalt hopper in order to maintain the desired temperature. The thermostatic controller may allow an operator to select a desired temperature for the asphalt.
