Abstract

"A laboratory testing program was developed to formulate a relationship which could be used to estimate the active zone depth at a given site with the index properties of the potentially expansive soils at the site. The testing program utilized standard consolidometers to incrementally add moisture to soil specimens to determine a swell versus soil suction index. Tests were performed on laboratory manufactured soil specimens of commercial clay to validate the testing methodology.

A QUATTRO PRO computer spreadsheet was developed to perform the calculations to determine the potential field surface heave for the soils tested provided they were at a site in the St. Louis area of Missouri. The spreadsheet then determined the heave versus depth of soil stabilization. The depth of stabilization corresponding to an allowable amount of heave was the active zone depth for the particular soil. This depth was then related to the P.I. of the particular soil tested. Recommendations were made for further research using this test procedure"--Abstract, page iii.
