Abstract
An extensible screed assembly for a bituminous paver incorporates a pair of screed extensions which are movable laterally outwards of the paver in order to pave roadway widths greater than that of the main screed. The screed extensions feature means by which the attack angle of each extension can be adjusted relative to the attack angle of the main screed and by which the alignment of each extension can also be adjusted relative to that of the main screed.
