Abstract
The screed assembly includes a screed plate and a screed frame. The screed plate includes a notch and the screed frame includes a tab that is inserted into the notch on the screed frame such that only screed plates and screed frames which include proper mating notches and tabs may be assembled together on road paving machines. In a preferred form of the invention, the width of the tab is approximately equal to the width of the notch to prevent lateral movement of the screed plate with respect to the screed frame when the screed plate is subjected to lateral impacts and forces during operation of the road paving machine.
