Quantify the economic and environmental impacts of using WMA and recycled materials in asphalt mixturesĪn Introduction to LCCA and LCA – The Tools of the Trade for Life Cycle Thinking.Understand historical trends in the use of recycled materials and WMA.Learn how the survey supports and enhances FHWA’s programmatic goals.This webinar will provide the latest data on the use of materials such as reclaimed asphalt pavement (RAP), recycled asphalt shingles, (RAS), WMA and more. Speakers: Tim Aschenbrener, P.E., Federal Highway Administration, Joseph Shacat, Director, Sustainable Pavements, NAPA and Brett Williams, Director, Engineering & Technical Support, NAPAĭescription: Since 2009, NAPA and FHWA have been collecting data on the use of recycled materials and warm-mix asphalt (WMA) technologies in the asphalt pavement industry. The Results Are In: NAPA and FHWA's Recycled Materials and Warm Mix Survey Complaints about registered providers may be sent to RCEP, 1015 15th Street, NW, 8th Floor, Washington, DC 20005. To be eligible for the credits, individuals must remain signed in for the entire webinar, including for any question and answer session following the presentations.ĪPA/NAPA will report credits earned to the Registered Continuing Education Program (RCEP). APA/NAPA’s webinar program awards PDH credits only to the registered individual, and not to other members of a group that view the webinar together.
PDHs: Professional engineers (PEs) who register and attend the entire webinar as an individual will be awarded up to 1.5 Professional Development Hours (PDHs). See the latest award-winning perpetual pavements.Use modern computational design tools for perpetual pavements.Understand pavement concepts to compute maximum pavement thicknesses.Design criteria needed to achieve an asphalt perpetual pavement.This webinar will discuss material and design selection, current perpetual pavement thickness practices, and present the latest award-winning perpetual pavements. Dave Timm, Professor of Civil and Engineering, Auburn Universityĭescription: An asphalt perpetual pavement, properly designed and constructed, lasts longer than 50 years without requiring major structural rehabilitation or reconstruction, and needs only periodic surface renewal in response to distress confined to the top of the pavement.
