The American Concrete Pavement Association sees good prospects for mainline paving and overlay projects this year, with overall volume nearly matching last year’s levels. “We expect 2019 market volume to be about 51.5 million square yards. The current projection for 2020 is about 50.2 million square yards. Although this represents a slight decrease of 2.5 percent, the change is attributed to several strong state reconstruction projects and new alignment programs completed in 2019,” says ACPA CEO Gerald Voigt.
Concrete paving is pretty complex and achieving quality, long-lasting results requires skill, the right equipment, and advanced technology. At its root, pavement is an outdoor floor … a hardscape surface covering that is driven or walked on. One of the major advantages of concrete pavements is they are typically stronger and more durable than other types of surfaces. They also can be grooved to provide a tough, skid-resistant surface. A notable disadvantage is that they typically can be more time-consuming to construct. Thus, concrete contractors have turned to technology for production-enhancing efficiencies and improved results.
