“…Primary "sulfate-induced heaving" problems arise when natural sulfate rich soils are stabilized with calcium-based additives (Puppala et al, 2004), also known as "sulfate attack." This heave is known to severely affect the performance of pavements, and other geotechnical structures built on sulfate rich soils stabilized with calcium-based additive (Hunter, 1988;Mitchell and Dermatas, 1990;Petry and Little, 1992;Rajendran and Lytton, 1997;Rollings et al, 1999;Puppala et al, 2004).…”

According to current understanding, "low to moderate" and high sulfate soils are those with sulfate less than 2,000 ppm and more than 2,000 ppm, respectively (Kota et al, 1996;Mitchell and Dermatas, 1990;Puppala et al, 2002;Rao and Shivananda, 2005).…”

“…Due to limitations in the linear shrinkage bar test, researchers utilized a three-dimensional volumetric shrinkage strain test method, originally developed at UTA by Puppala et al (2004). This method uses a cylindrical compacted soil specimen, which was subjected to the drying process, and then measures volumetric, axial and radial shrinkage strains of the soil specimen by using a digital imaging technology.…”

Expansive soils have long been recognized as problematic because they cause failure to civil structures constructed above them. The main problem of these soils can be attributed to poor understanding of the volume changes caused by moisture fluctuations. Current swell and shrinkage characterization models are limited by both the lack of standardized tests and tests that employ volume changes in uniaxial direction. In the present research, a comprehensive laboratory investigation was undertaken to study the volume change related swell-shrinkage behaviors of five different types of expansive clayey soils sampled from various regions in Texas, USA. Extensive experimental programs consisting of basic, chemical and mineralogical soil properties were first determined. Three-dimensional free swell and shrinkage tests were performed on all soils at various compaction moisture content conditions. Soil water characteristic curves (SWCCs) of all test soils were determined by studying the suction potentials of these soils over a wide range of moisture contents. Volume change measurements of soils showed a good correlation with soil properties, including plasticity and soil compaction properties. SWCC results also showed a clear variation in SWCC profiles of soils with respect to soil plasticity. Overall, a large database of soil properties was developed and is presented here. It includes physical and mineralogical properties, and engineering test results including swell, shrinkage and SWCCs. This is an author-produced, peer-reviewed version of this article.

These failures were found to be related to sulfate reactions that cause the formation of two minerals: ettringite and thaumasite.…”
