Marshall Hammer versus Gyratory Compaction: Validating Equivalence for P401 Mixtures

This webinar presents the research conducted by NCAT and UNR to determine the equivalent 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.

Presenters

• Randy West, Director, National Center for Asphalt Technology (NCAT) at Auburn University
• Carolina Rodezno, Associate Professor, National Center for Asphalt Technology (NCAT) at Auburn University
• Adam Hand, Professor, University of Nevada, Reno
  

Highlight features & benefits

• 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
