Abstract

This investigation showed that a true functional relationship, valid over a wide range of experimental conditions, does not exist between the results obtained by two methods of evaluating the strength of a cement-treated sandy soil. These two methods are the California Bearing Ratio test and the unconfined compressive strength test. However the equation, log CBR = 1.115 + 0.660 log UCS, can be used as a working relationship between the two tests under varying experimental conditions. It was concluded that a true functional relationship likely does exist for a given experimental condition, i.e., where only one experimental condition varied at a time. Results obtained in this investigation suggest that a strength criterion of 250 psi for stabilized sand is unreasonable as it fails to take into account the strength gained due to the soil-cement being confined laterally.
