Abstract

The proposed study will develop and fabricate a lab-scale apparatus for comparative testing of traditional and polymeric expansive soil treatment technologies. The proposed apparatus will then be used to compare traditional (lime and fly ash) and commercially-available polymer treatment technologies to natural (un-amended) expansive soils. The proposed apparatus is necessary to effectively carrying out this comparative evaluation due the different mechanisms by which traditional stabilizers and polymeric stabilizers mitigate soil shrink-swell behavior. Finally, the procedures developed during the proposed study will be codified into a standard methodology for testing of innovative expansive soil treatment technologies (e.g., use of different recycled materials).
