    Stabilization of poorly graded sand in full-scale applications is challenging. This thesis evaluated cement-stabilized sand and had two objectives: (1) evaluation of stabilized material using the PM device to quantify engineering properties for future comparison to alterative materials and to investigate the effectiveness of the device with sand and (2) investigation of the merits of alternative application of cement to sand to benchmark against other topically applied materials. The PM device was successfully used to recommend 10% cement for field studies with one sand, successfully allowed data collection in laboratory and field applications, and its potential in sand seems promising though more overarching conclusions on characterization of sand using the PM device are withheld for subsequent efforts. Topical application methods developed in this thesis were able to percolate cement into sand and produce an average estimated unconfined compressive strength of 245 psi measured on cores that were 2.5 inches thick.
