Web Archive: Utilizing RAP in WMA Webinar

May 07, 2012

Thanks to John Christensen for presenting our latest webinar, Utilizing RAP in WMA. Listeners hailed from 23 states, 4 Canadian Provinces, and 3 Countries (USA, Canada, and the Czech Republic). If you missed the original webcast, you can listen to the archive here. John's audio is a bit soft at first and gets louder after that.

To recap: using high amounts of recycled asphalt pavement (RAP) in your mix design can save significant amounts of money in addition to being good for the environment. High-RAP mixes don't always excel in workability and can be difficult to manage. The solution has always been to go hotter so a high-RAP warm mix design seems counter intuitive. This webinar addressed how Evotherm WMA can be combined with high percentages of RAP and focuses on RAP activation, workability, and case studies.
