Effects of Fines Content on Hydraulic Conductivity and Shear Strength of Granular Structural Backfill

For cast-in-place abutments and retaining walls, structural backfill is preferred to be free-draining, which generally implies less than 5% fines content. This fines content is expected to eliminate the need to design for hydrostatic pressures. The availability of high-quality structural backfill wi...
