Why do construction zones that involve paving with Portland Cement take so long to be taken down as compared to hot mix asphalt paving?
A. Concrete pavement construction is a difficult and time consuming process. Although the concrete industry purports to be able to quickly place concrete with state of the art pavers and cure it rapidly with new mix additives, the fact remains that it is much more time consuming than paving with HMA. Continuously reinforced concrete pavements require the careful placement of steel within the slab matrix area and jointed pavements require cutting expansion joints. These and other issues result in far more time spent by contractors in the construction zone. HMA placement, on the other hand, causes few traffic disruptions with paving equipment in and out of the construction zone in a very short period of time. With today’s heavy traffic problems, getting the work done quickly and efficiently while still providing high quality pavements is of great benefit to owners and the traveling public.
