ABSTRACT:
A screed assembly has a screed plate that is formed of a material having a thermal conductivity of less than about 25 W/mK, and a thermal barrier material having a thermal conductivity of less than about 0.5 W/mK that substantially covers an upper surface of the screed plate. The low thermal conductance properties of the screed plate obviate the need for auxiliary heating systems to preheat or maintain the screed plate in thermal equilibrium with a paving material.
