Highway Paving Linear Schedule

This linear schedule illustrates how repairs and resurfacing of a major interstate highway can be completed within lane closures, to keep traffic moving through the work zone. The overall construction sequence is dictated by the use of a planing (milling) machine that grinds down the existing roadway surface, and a paving machine that lays down new hot mix asphalt (HMA). As soon as these key activities are done in the eastbound lanes, crews and equipment move over to the westbound lanes to continue their work. Colored block shapes indicate the duration of each lane closure, and the map and roadway sections were clipped from the engineering drawings to provide helpful visual aids for discussing the work.
