THE EFFECTS OF CONVENTIONAL SOIL SAMPLING METHODS ON THE ENGINEERING PROPERTIES OF COHESIVE SOILS IN LOUISIANA
A comprehensive literature study is performed. Eighteen hundred samples from six sampling sites representing several typical geologic formations of Louisiana are obtained. About 1700 field and 6500 laboratory tests are performed. Engineering properties of soils studies showed inherent variations. Both block and 5 inch diameter samples provided specimens with least amount of disturbance. Sampling with small diameter thin wall tubes caused serious disturbances. The stress-strain relationship of soils were affected by sample size. Long-term (15 days or longer) storage of samples caused measurable changes in their properties X-ray analysis of samples showed internal discontinuities and disturbances caused by sampling and handling. /FHWA/
