Sustainability

Not only does asphalt provide the smoothest, quietest ride, it also is the most sustainable option for paving. Over the years, the asphalt pavement industry has been a constant innovator in finding ways to make its products more environmentally friendly – from reclaiming old asphalt pavements and rejuvenating their component parts for use in new pavements to the incorporation of recycled materials to the adoption of energy-saving warm-mix asphalt technologies.

One of the keys to sustainability is long life. With Perpetual Pavements, asphalt pavements have an extremely long lifespan.

A Perpetual Pavement is constructed so that distress occurs in the top layer only. The only rehabilitation required is removal of the surface and resurfacing with an asphalt overlay. Using current pavement technologies, this can be done on an infrequent basis – every 15 to 20 years. The reclaimed material is then recycled. Perpetual Pavement is the ultimate in sustainable design and construction.

While the Perpetual Pavement name is relatively new, the concept is not. In fact, more than 50 pavements have received the Perpetual Pavement Award since 2001. These award-winning roads, streets, highways and airport runways have been in place for at least 35 years, with a minimum of  maintenance and no full-depth reconstruction.

Recycling

As early as 1993, the Environmental Protection Agency and Federal Highway Administration identified asphalt pavement as America’s No. 1 recycled product in a report to congress. It continues to be reclaimed and reused at a greater rate than any other product in the U.S. A wide range of waste materials are now incorporated into asphalt pavements, including ground tire rubber, slags foundry sand, glass, and even pig manure, but the most widely used are reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS). The use of recycled materials in asphalt pavements saves about 50 million cubic yards of landfill space each year.

NAPA, in partnership with the Federal Highway Administration (FHWA), is quantifying the use of these technologies through industry surveys. According to the latest survey data, during the 2014 construction season, more than 71.9 million tons of RAP and nearly 2 million tons of RAS were put to use in new pavements in the United States, saving taxpayers more than $2.8 billion. Also, about a third of all asphalt pavement mixture produced in the country that year was made using warm-mix asphalt (WMA) technologies.

When reclaimed asphalt pavement and shingles are reprocessed into new pavement mixtures, the liquid asphalt binder in the recycled material is reactivated, reducing the need for virgin asphalt binder. Using reclaimed materials also reduces demands on aggregate resources. Warm-mix asphalt technologies allow asphalt pavements to be produced at lower temperatures, which means reduced energy demands, as well as lower emissions during production and paving.
