ABSTRACT:
An asphalt paver screed includes a linkage mechanism connecting a main screed and at least one extender screed. The linkage mechanism controls movement of the extender screed relative to the main screed (via a pair of upper and lower frames connecting the extender screed and main screed) along three generally perpendicular axes. The linkage mechanism includes a plurality of links with at least one elongate lateral link extending along a lateral axis generally parallel to a first horizontal axis, at least one elongate fore/aft link extending along a fore/aft axis generally parallel to a second horizontal axis, and at least one selectively length-adjustable link extending along an axis generally parallel to a third vertical axis. The length adjustable link permits selective adjustment of vertical spacing and sloping between the main screed and the extender screed.
