ABSTRACT:
A floating screed for asphalt paving machines has the front edge of its sole plated and bullnose sloping rearwardly from the center to assist lateral flow of the hot asphalt material in front of the main screed and to the front of screed extenders.
The bullnose for the sole plate is separate from the sole plate and consists of a pair of bullnose pieces. The construction is such that adjustment of the controlled dishing and warping of the sole plate can be more easily performed.
