    Abstract

    The engineering and material properties of controlled low-strength material (CLSM) can be altered through the use of air-modifying additives, thereby broadening potential end-uses for CLSM. Air-modified low-water content CLSM retains the compressibility, shear, load-bearing, and flowability characteristics of non-air- modified CLSM, while improving permeability, subsidence, bleeding, and freeze-thaw properties. This paper details test procedures and results of several soil and other applicable backfill tests including compressive strength, direct shear, California bearing ratio (CBR), modified (cyclic loading) CBR, triaxial shear, incremental consolidation, thermal conductivity, water permeability, air permeability, freeze-thaw, and bleeding.
