A paving machine (20) employs an electrically heated screed assembly (30) to uniformly heat a screed plate (46) of the machine. Uniform heating is achiev ed by inserting a thermally conductive plate (62) between electrical heating elements (60) and the screed plate (46). An insulation layer (68) may be provided above the heating elements (60) to direct the heat downward into th e thermally conductive plate (62). The heat spreads relatively uniformly throughout the termally conductive plate (62), thereby uniformly heating the screed plate (46). A clamping mechanism (74) is also provided that, when tightened, provides a compressive force, thereby holding the assembly in place. When released, the pressure is alleviated, thus permitting a heating element to be removed for repair or replacement without the need to remove t he screed plate.
