Virtual Learning

Asphalt Recycling: A National Perspective with MnROAD Findings

  • May 10, 2019 (9:30 - 11:30 am CT; 8:30 - 10:30 am MT)
    Virtual Learning (desktop or laptop access)



A link to the webinar will be emailed to registered participants approximately 2 days prior to the presentation. Participants will be able to access the webinar from any desktop or laptop.

The above opportunity and more can be accessed by visiting the TLN Learning Management System (LMS).


The presentation will provide information about asphalt recycling; including key research, best practices and successful implementations. Asphalt recycling methods have evolved over the years. Find out about research, current industry trends, performance results, and design criteria. The presenters will discuss how project applications have fared and how agencies have:

  • Balanced mix designs
  • Use of recycling agents
  • Best practices for control of RAP mixes
  • What to watch for during construction
  • MnROAD test section review
  • MnROAD findings and MNDOTs implementations
  • Research efforts

MnROAD is one of the most sophisticated, independently operated pavement test facilities of its type in the world; owned and operated by the Minnesota Department of Transportation working with its partners. The NDDOT and UGPTI/NDLTAP recently joined this effort through the National Road Research Alliance (NRRA). Located near Albertville, Minnesota, MnROAD works in conjunction with MnDOT's Materials Lab. It finds ways to make roads last longer, perform better, cost less to build and maintain, built faster and have minimal impact on the environment.


Dr. J. Richard Willis is the Vice President of Engineering, Research, and Technology for the National Asphalt Pavement Association where he assists the asphalt industry with issues related to recycled materials including RAP, RAS, and RTR in asphalt mixtures, pavement vehicle interaction, pavement design and environmental product declarations. Before joining NAPA, he served as an associate research professor for the National Center for Asphalt Technology at Auburn University where he served on research projects related to asphalt recycling and sustainability. Just like a good mix design, he tries to promote balance in all areas of life. He has a deep passion for education and tries to ensure that people remember the message even if they forget the man.

Ben Worel is the MnROAD Operations engineer with the Minnesota Department of Transportation. Day-to-day activities consist of conducting research and facilitating partnerships including National Road Research Alliance. He is a registered professional engineer in the state of Minnesota and his work experience has focused primarily in the areas of pavement research and pavement management. He has been with MnDOT for 22 years. Before that, he worked for seven years with Braun Intertec as a Minnesota-based consultant and worked on the Long-Term Pavement Performance Project. He is chair of TRB’s AFD40 Committee on Full Scale Accelerated Pavement Testing and is a member and friend to a number of other TRB committees.
