FIELD STABILIZATION OF CHINLE CLAY BY ELECTRO-OSMOSIS AND BASE EXCHANGE OF IONS
A large scale soil stabilization project was initiated in July 1973. A 500-foot section, which is part of a 1300 foot cut on I-40 35 miles east of Holbrook, Arizona, was selected as the test site. The natural soil in the area is Chinle clay, a highly expansive Montmorillonite clay. The stabilization technique used on the Chinle clay was treatment with a 0.4N solution of KCl and electrochemical action. Results show that this method of soil stabilization produced a moderate decrease in the swelling characteristics of the Chinle clay, i.e., about a 50% decrease in expansive pressure and a 36% decrease in percent swell. Moreover, the electron miciographic and x-ray diffraction data have indicated some probable causative factors for the decrease in the swelling characteristics of the Chinle clay.
