Results of Research in Sampling Loessial Soil for Inplace Unit Weight Determinations

摘要

Because of the difficulty encountered in sampling loessial material, it became necessary to investigate other sampling techniques to find a more reliable method. In May 1984, an investigation program was developed for the North Loup Division to evaluate sampling techniques in loessial soil. In most cases, inplace dry unit weights obtained from hollow-stem auger samples were reasonably close to values obtained by the sand-cone method. Sample recovery was consistently high, and sample quality was good when the hollow-stem auger was used for sampling.
