The latest NAPA/FHWA survey of asphalt producers' use of recycled materials and warm-mix asphalt find that nearly a quarter of all asphalt produced during the 2012 construction season was produced using warm-mix asphalt technologies! The survey, conducted by NAPA under contract to FHWA, found that about 86.7 million tons of WMA was placed 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.
Contractors and DOTs alike are boosting their use of recycled material. We are working with several to even combine the powers of Evotherm and Evoflex to create high-recycled content warm mixes. The NAPA survey found that about 68.3 million tons of reclaimed asphalt pavement (RAP) and 1.86 million tons of reclaimed asphalt shingles (RAS) were used in new asphalt pavement mixes in the United States during in 2012. For the first time since the start of this survey in 2009, the amount of RAP and RAS used by producers exceeded the amount collected.
