Thesis (M.S.C.E.)--The University of Texas at Arlington, 2002.

A series of unconfined compressive strength (UCS, ASTM D 2166), unconsolidated undrained triaxial (UU, ASTM D 2850), and resonant column (RC, ASTM D 4015-92) tests were conducted on several chemically stabilized specimens of high-plasticity, sulfate-rich expansive clay from southeast Arlington, Texas. Test results were used to assess the influence of cyclic drying and wetting on strength and stiffness properties of treated soil. Specimens were tested for different stabilized types, stabilizer dosages, compaction moisture contents, and number of drying-wetting cycles.

520 $a A series of unconfined compressive strength (UCS, ASTM D 2166), unconsolidated undrained triaxial (UU, ASTM D 2850), and resonant column (RC, ASTM D 4015-92) tests were conducted on several chemically stabilized specimens of high-plasticity, sulfate-rich expansive clay from southeast Arlington, Texas. Test results were used to assess the influence of cyclic drying and wetting on strength and stiffness properties of treated soil. Specimens were tested for different stabilized types, stabilizer dosages, compaction moisture contents, and number of drying-wetting cycles.
520 $a In this work, three novel chemical stabilizers were used: (1) Sulfate resistant “Type V” cement, (2) Low calcium “Class F” fly ash, and (3) Lime mixed with polypropylene fibers. Soil's strength and stiffness properties investigated include unconfined compressive strength (q<sub>u</sub>), undrained shear strength (s<sub>u</sub>), dynamic shear modulus (G), and material damping ratio (D). An 8%-by-weight dosage of lime, mixed with 0.3%-by-weight polypropylene fibers, appears to yield best soil performance under cyclic drying and wetting.
