NAPA National Asphalt Pavement Association

NAPA & FHWA Seek Survey Participants

The National Asphalt Pavement Association (NAPA) and the Federal Highway Administration (FHWA) need to hear from you about warm mix asphalt and reclaimed/recycled materials. NAPA, in partnership with FHWA, is conducting an industry survey of 2012 production levels and the use of recycled materials and warm mix on a state-by-state level.

NAPA and FHWA have tracked usage of reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS), and warm mix asphalt (WMA) since the 2009 construction season. The results of the 2011 season were released in April and show that the use of reclaimed materials alone conserved about 3.7 million tons of virgin liquid asphalt binder, saving about $2.2 billion.

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. Full results of the 2011 survey are available here. Asphalt mix producers may participate in the survey by clicking here.

The survey must be completed by July 31. It is recommended that respondents download a printed version of the survey from the NAPA website by clicking here to ensure that all the relevant data is at hand before beginning the process. Survey participants will receive a complimentary copy of the report once it is released.

“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,” says Kent Hansen, NAPA Director of Engineering, who is administering the survey.

Data from the survey will be kept completely confidential and will be used only for the purposes of determining quantities. Data will be reported by state only, and no company-specific information will be disclosed or used for any purpose.

Because data is being aggregated by state, companies or branches active in more than one state need to complete a separate questionnaire for each state. If a plant provides mix for more than one state, the tonnage should be divided accordingly.

The 2011 survey included responses from 49 states and Puerto Rico. Responses from all 50 U.S. states, the territories, and the District of Columbia are desired for the current survey.

New for the 2012 construction season, the survey asks about other recycled materials used in asphalt mixtures, such as ground-tire rubber and slag.

Survey results will be shared with industry and agencies to help in the implementation of recycling and warm-mix technologies. This will help the industry when working with agencies and the public to promote asphalt pavements.
