    Input sought from all U.S. asphalt mix producers by April 1 for annual survey

    LANHAM, MD — Every asphalt mix producer in the United States is asked to participate in the National Asphalt Pavement Association’s (NAPA) annual survey on the use of recycled materials and warm-mix asphalt. This survey is conducted by NAPA under a cooperative agreement with the Federal Highway Administration (FHWA) and is an important tool for tracking the use of sustainable practices by the asphalt pavement industry.

    The confidential survey gathers information about the use of these materials during the 2018 construction season. Responses are sought from producers of all sizes and from every community in all 50 U.S. states as well as all U.S. territories.

    “By providing answers to the questionnaire, asphalt mix producers will improve the accuracy of the findings and will help ensure the industry’s environmental impacts are properly understood by federal and state agencies as well as the public,” stated NAPA Director of Engineering and Technical Support Brett Williams, who is administering the survey. “The survey tracks implementation of these technologies and enables NAPA, FHWA, industry and others to highlight sustainable practices in the asphalt pavement industry and to focus efforts to expand future implementation growth.”

    NAPA and FHWA have tracked usage of reclaimed asphalt pavement (RAP), recycled asphalt shingles (RAS) and warm-mix asphalt (WMA) annually since the 2009 construction season. The results from the 2017 construction season were released in July 2018, showing that more than 78.6 million tons of recycled material was used in asphalt pavement mixtures during 2017. This includes RAP and RAS, as well as other reclaimed and recycled materials, such as ground tire rubber, steel and blast furnace slags, coal combustion products and cellulose fibers.

    In addition, about 147.4 million tons — nearly 39 percent of total asphalt pavement mixture produced in 2017 — used WMA technologies to reduce mix-production temperatures. 

    The full results of the 2017 survey are available at www.AsphaltPavement.org/recycling.
