SPR-4827: Develop a Performance-Related QA Testing Method for Accepting MSE Wall Coarse Aggregate Reinforced Backfill Compaction Acceptance

INDOT intends to only allow coarse aggregates for MSE wall backfill. Accepting compaction of such materials currently requires a method specification approach in which acceptance is based on how well the contractor follows a prescribed construction methodology that requires constant supervision from project inspection personnel. This research study aims to develop performance-related acceptance criteria and/or testing procedures for MSE wall backfill compaction.
