NAPA and ARRA release survey to track in-place recycling technologies

The National Asphalt Pavement Association (NAPA) and the Asphalt Recycling & Reclaiming Association (ARRA) have announced a partnership to measure the use of in-place recycling technologies for asphalt pavements during the 2019 construction season. The survey is being conducted under contract with the Federal Highway Administration (FHWA).

NAPA and ARRA are encouraging every contractor in the U.S. engaged in hot-in-place recycling, cold-in-place recycling, cold central plant recycling and full-depth reclamation of asphalt pavements to participate in the confidential survey.

In-place recycling technologies are a suite of construction techniques and processes used to rehabilitate pavements. They generally involve on-site pulverizing of bound pavement layers, blending an emulsion, foamed asphalt and/or a recycling agent into the material, and then spreading and compacting it to form a new pavement structure.

“These in-place recycling technologies are an important part of the toolbox, particularly for local agencies,” says Rick Church, ARRA’s executive director. “By quantifying the use of these technologies, we can help state and local officials better understand the wide-spread acceptance of in-place recycling, as well as quantify its sustainable benefits.”

All information provided for the survey will be kept confidential, and results will primarily be reported at the national level. Regional results may be reported if enough participation from each region is received to ensure the data remains anonymous. The survey can be found here.

“For more than a decade, NAPA has tracked the use of reclaimed asphalt pavement and other recycled materials in new asphalt pavement mixtures,” says Brett Williams, NAPA’s director of engineering and technical support, who is administering the survey. “With this survey, we hope to better quantify how 100-percent recyclable asphalt pavements are being used and reused nationwide.”
