BMD Round Robin: Phase 2 begins

Recently, VTRC initiated efforts for Phase 2 of the Balanced Mix Design Research Effort. Phase 1 focused on testing identical asphalt mixture samples across nearly 50 laboratories around Virginia and the US. Each lab received two sets of gyratory pills, one set had a high IDT index value, and one had a low IDT index value. VTRC has provided results of Phase 1 at previous virtual meetings and conferences. Phase 2 will build upon the Phase 1 results using almost identical mixes. Each participating lab will receive buckets of mix to condition, compact, and test. All results will be provided to VTRC for analysis.
