ABSTRACT:
The disclosure relates to a floating screed type asphalt paver provided with extendable, retractable auxiliary screed units which, in their retracted positions, are mounted in front of the main screed and carry edger plates. By mounting the screed extensions in front of the main screed units, it is possible to retract the extension units without interrupting paving operations. A strike-off plate may be positioned in front of the extension units to limit the presence of paving material between them and/or the extension units may be provided with bevelled inner edges for displacing such material during retraction. Novel arrangements are provided for mounting and adjusting the screed extensions.
