Soil Mechanics Laboratory Manual is the market-leading manual for junior-level soil mechanics/geotechnical engineering laboratory courses. It teaches students the essential properties of soils and their behavior under stress and strain and provides clear, step-by-step explanations for conducting typical soil tests. The careful explanations of laboratory procedures help foster students' independence, reduce errors, and improve safety. Written by Braja M. Das, respected author of acclaimed texts in geotechnical and foundation engineering, this manual also provides a detailed discussion of the AASHTO Classification System and the Unified Soil Classification System.
This seventh edition is enhanced by five appendices, including the newly added Appendix E that contains semi-log and linear duplicate graph paper.
Comprehensive selection of class-tested labs
New photograph program to better illustrate textual material
Includes sample calculations and graphs relevant to each laboratory test
