Every Day Is Earth Day for Asphalt

IS 138 2nd Annual Asphalt Industry Survey on the Usage of RAP, RAS & WMA, 2009-2011In time for Earth Day, NAPA and FHWA have released a new survey of sustainable construction practices in the asphalt pavement industry. The survey, which covers the 2011 construction season, studies the usage of reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), and warm-mix asphalt (WMA). The use of recycled materials in asphalt pavements saved taxpayers more than $2.2 billion dollars during the 2011 paving season.


According to the survey, about 21.2 million barrels of liquid asphalt binder were saved through the use of RAP and RAS during 2011. Also, about 19 percent of all asphalt produced in the country that year was made using WMA.


The survey was conducted in mid-2012. Results from 203 companies with 1,091 plants in 49 states and Puerto Rico, along with data from 32 State Asphalt Pavement Associations, were used to calculate industry estimates for total tonnage. A copy of the full survey, including a state-by-state breakdown of the data, is available at www.asphaltpavement.org/recycling.
