The primary purpose of this book is for the teaching of soil testing. Can be of value as a reference book for practicing engineers and for personnel in soil laboratories. There are many conditions, such as soil disturbance during sampling and unknown boundary conditions in nature, that require the engineer to use intelligence and experience in applying the results of laboratory tests to an actual soil problem. In many particular problems the results of laboratory tests can do no better than serve as a guide to the designer. For such problems field tests are often required. Even though this book is devoted entirely to laboratory testing, I hope that it will aid the student in attaining the proper perspective on the role of laboratory testing in soil mechanics.
