Geotechnical engineers are commonly faced with the need to perform ground
improvement techniques to achieve the necessary bearing capacity for a project. Some of
the most common techniques involve the excavation and replenishment of problematic
geomaterial with one of better quality. Common projects, such as road embankments and
retaining walls, also require the selection of backfill material. The guidelines for selecting
backfill material are typically limited to complying with certain gradation bands, relative
densities and allowable fines content.
Round-grained silica sand, and beach sand from Boca Raton, FL, were used to generate
a total of 16 binary granular mixtures containing different amounts of finer material, for
which a series of direct shear tests were conducted. Based on the experimental results, it
may be possible to provide an alternative criteria for selecting backfill material based on
granulometric parameters and the amount of finer material. / Includes bibliography. / Thesis (M.S.)--Florida Atlantic University, 2016. / FAU Electronic Theses and Dissertations Collection
