Project Details

Title:Representative Testing of Expansive Soil Treatment Technologies for Transportation Earthworks
Principal Investigators:Joseph Scalia and Christopher Bareither
University:Colorado State University
Grant #:69A3551747108 (FAST Act)
Project #:MPC-538
RiP #:01650579
RH Display ID:15693
Keywords:durability, earthwork, expansion, infrastructure, polymers, service life, soil stabilization, soil tests, swelling soils


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).
