The National Asphalt Pavement Association (NAPA) and the Federal Highway Administration (FHWA) are asking asphalt mix producers for their participation in a survey on warm-mix asphalt and reclaimed/recycled materials. The survey deadline is July 31st.

The National Asphalt Pavement Association (NAPA) together with the Federal Highway Administration (FHWA) is conducting an industry survey geared toward asphalt mix producers. The survey will gauge the 2012 production levels, and the use of recycled materials and warm mix on a state-by-state level.

Since the 2009 construction season the NAPA and FHWA have tracked usage of reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), and warm-mix asphalt (WMA).

From 2009 to 2011, this survey has documented a 19 percent increase in RAP use, a 52.5 percent increase in RAS use, and a 309 percent increase in WMA use. The results of the 2011 season were released in April and showed that the use of reclaimed materials alone conserved about 3.7 million tons of virgin liquid asphalt binder, saving about $2.2 billion.

"Recycled materials and warm-mix asphalt technologies are critical to the sustainable future of the asphalt pavement industry. We need your help in benchmarking the industry's progress in putting sustainable practices into use," stated Kent Hansen, NAPA Director of Engineering, who is administering the survey.
