Soil Mechanics Laboratory Manual 8e, Braja M. Das


Soil Mechanics Laboratory Manual 8th Edition PDF Download Ebook. Braja M. Das covers the essential properties of soils and their behavior under stress and strain and provides clear, step-by-step explanations for conducting typical soil tests. This market-leading text offers careful explanations of laboratory procedures to help reduce errors and improve safety.

This book also provides a detailed discussion of the AASHTO Classification System and the Unified Soil Classification System. Most of the test procedures were specially prepared for the geotechnical laboratory. The test procedures are based on BS standards and some ASTM standards. However, in various cases the test procedure was adapted to the type of equipment available in the laboratory.

This means that often a realistic compromise had to be found between strict requirements and practical possibilities. Whenever tests have to be performed following a prescribed standard, always consult that standard before testing.

New to this book is update to the test designations of the American Society for Testing and Materials (ASTM). All tests now include general guidelines for preparing laboratory test reports. Ultimate shear strength and ultimate friction angle are now introduced in Chapter 16: Direct Shear Test on Sand. This text includes empirical correlations for the coefficient of permeability and maximum dry unit weight and optimum moisture content to use and compare with the lab tests results.
