BEHAVIOR OF COMPACTED SOIL IN TENSION

Additional test results and comments are presented on the tensile characteristics of fine grained soil obtained using the double punch test. The tensile strength increases as water content decreases with maximum tensile strength occurring on the dry side of optimum water content conditions. However, after a certain limit is reached, decreasing water content will create shrinkage/crcking of the soil, causing a reduction in tensile strength. The rate of increasing or decreasing of tensile with respect to water content will depend on soil types. The ratio of unconfined compressive strength to tensile strength is dependent not only on molding water content but also on soil types as reflcted by the plasticity index. It was found that a curvilinear relationship exists between this ratio and the plasticity index. It was also found that tensile strength-cohesion ratio increases linearly with increasing plasticity index. Comments are also made on the effect of the loading rate on the tensile strength, the variation of tensile strength with the addition of additives including lime, flyash and cement, and tensile strength measurement by the split tensile test and the double punch test.
