ELECTROCHEMICAL HARDENING OF EXPANSIVE CLAYS

This paper is concerned with a large-scale swelling soil stabilization project that was undertaken by the Arizona Department of Transportation in July 1973. The site chosen for the study was approximately 146 m (480 ft) of the westbound lane on I-40 about 56 km (35 miles) east of Holbrook, Arizona. The stabilization technique used was electroosmosis and a 0.4 N KCI solution for inundating the clayey mass of the site. This resulted in an average 36 percent decrease in the percentage of swell and a 60 percent reduction in swell pressure of the Chinle clay. X-ray diffraction and electron micrograph data indicated possible causative factors of the reduction in swell pressure and percentage of swell.
