Abstract
Asphalt paving machine includes screed assembly, plurality of lower and upper plate fasteners, and upper and lower screed plates, each having openings, and an electric heater at least partially disposed between the plates. Upper and lower plate fasteners extend into openings of the respective upper and lower screed plates and bores of a frame portion of the screed assembly to couple the plates to the frame portion. The upper plate fasteners couple the upper screed plate to the frame portion independently of the lower screed plate, so the lower plate is displaceable from the upper plate and the frame portion.
