ABSTRACT:
An apparatus and method for securing a screed plate to a frame member of a screed assembly is disclosed. A leading edge portion of the screed plate is secured to the frame member by a number of fastening assemblies each of which includes an upper fastening block, a lower fastening block, and a bolt. The upper fastening block is welded to the frame member, whereas the lower fastening block is welded to the screed plate. Rotation of the bolt causes the fastening blocks, and hence the frame member and the screed plate, to be secured to one another. The bolt is disposed at an angle relative the screed plate thereby allowing access thereto from a rear portion of the screed assembly. Such a configuration allows the screed plate to be exchanged without the need to remove the screed assembly from the tractor associated with the paver. Such a configuration further allows the screed plate to be exchanged without the need to remove a number of deflector plates associated with the screed assembly.
