Marshall Hammer versus Gyratory Compaction

Tuesday, December 16, 2025
2:00 PM - 3:00 PM (EST)

Event Details

Faculty from the National Center for Asphalt Technology (NCAT) and the University of Nevada, Reno present research determining the number of gyrations in a Superpave Gyratory Compactor to achieve the same density obtained by 50-blow and 75-blow compaction with a Marshall hammer. 

During this webinar you'll:

  • Understand how asphalt mixture compaction methods are applied in FAA P401 and P403 specifications 
  • Learn how researchers determined equivalent gyration levels for each compaction method 
  • Explore the study's findings and how they increase confidence and consistency in airfield asphalt mixtures 

Don't miss this opportunity to deepen your understanding of compaction processes!
