NAPA In The News - Warm-Mix Asphalt Use Reaches New Heights

Warm-Mix Asphalt Use Reaches New Heights The latest national survey of asphalt producers’ use of recycled materials and warm-mix asphalt finds nearly a quarter of all asphalt produced during the 2012 construction season was made using warm-mix asphalt technologies.  The survey, conducted by NAPA under contract to FHWA, found production totaled 86.7 million tons of WMA in 2012. This is a 26 percent increase since 2011 and a 416 percent increase in the use of warm mix since the survey was first conducted in 2009.  The survey also found about 68.3 million tons of RAP were used in new asphalt pavement mixes in the United States during 2012. For the first time since the start of this survey in 2009, the amount of RAP used by producers exceeded the amount collected.  As of 2009, RAP usage showed a modest increase from 2011 to 2012; however, the 68.3 million tons used in 2012 is a nearly 22 percent increase since 2009.  Full Survey   Information from 2013 is now being collected.
