New survey finds recycling, energy-saving technologies for asphalt pavements increasingly adopted nationwide
NAPA / April 17, 2013
Lanham, Md. — Thanks to broad adoption of sustainable construction practices, the asphalt pavement industry saved taxpayers more than $2.2 billion dollars during the 2011 paving season through the use of recycled materials and energy-saving warm-mix technologies.
According to a survey conducted by the National Asphalt Pavement Association (NAPA) in partnership with the Federal Highway Administration (FHWA), about 66.7 million tons of reclaimed asphalt pavement (RAP) and 1.2 million tons of reclaimed asphalt shingles (RAS) were collected in the United States during 2011 for use in new pavements. Also, about 19 percent of all asphalt produced in the country that year was made using warm-mix asphalt (WMA) technologies.
“Asphalt pavements are the sustainable option for paving our nations’ roads and highways. With warm mix, we can use less energy to produce high-quality pavements, and RAP and RAS allow us reuse liquid asphalt, saving costs and preserving natural resources,” said John Keating, NAPA 2013 Chairman and President and COO East of Oldcastle Materials Inc. “While use of these technologies has increased dramatically, there is room to do more, and the asphalt pavement industry is ready to reach even higher levels of sustainability in road construction.”
