摘要:
In a slip-form paving apparatus, a forwardly disposed pavement forming assembly, such as an auger assembly and a strike-off plate, are pivotably mounted to the apparatus frame for movement between an operative disposition disposed adjacent a ground surface for distributing and forming paving material thereon generally into a desired form of pavement and an inoperative position more elevated from the ground surface for permitting access beneath the apparatus for depositing a starting quantity of the paving material during an initial start-up of the apparatus.
