The most current, comprehensive, and easy-to-follow soil mechanics lab manual available, this acclaimed volume provides detailed discussion of the AASHTO Classification System and the Unified Soil Classification System


Now in its ninth edition, Soil Mechanics Laboratory Manual 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 also offers careful explanations of laboratory procedures in order to help reduce errors and improve safety.

New to this Edition

  • Provides the associated ASTM standard at the beginning of the introductory section of each laboratory test
  • Adds the liquid limit test-fall cone method (Ch. 7); there is no ASTM standard for this test, so the British standard is given
  • Adds tests on the maximum and minimum densities of granular soil (Ch. 12)
  • Places the constant head and falling head permeability tests after the Proctor compaction test, as Chs. 13 and 14
  • Covers the consolidation test after the unconfined compression test, as Ch. 17
  • Adds several new photographs and figures
  • Properly identifies the location for recording test readings/measurements in the prescribed table(s)
  • Adds a brief description about the fundamentals of SI units to Ch. 1, "Laboratory Test and Preparation of Report"
  • Presents a more detailed description of U.S. sieve sizes and a list of commonly used British sieve sizes in Ch. 4, "Sieve Analysis"
  • Modifies Table 5-4 for data recording and other calculations to record test temperature for each reading (except for those cases in which a constant temperature bath is not used)
  • Adds a discussion on the plasticity chart and its uses in soil classification to Ch. 8, "Plastic Limit Test"


  • Provides detailed discussuion of the AASHTO Classification System and the Unified Soil Classification System

"This text offers a streamlined version of the ASTM standards, which is helpful for students. The example data sets provided within the lab experiments are quite valuable, and that is one of the reasons that I like this lab manual."--Charles E. Pierce, University of South Carolina

"This lab manual is designed and written in a clear and straightforward manner, which will make lab teaching and understanding easier. That is what students like and want."--Mamadou Fall, University of Ottawa

"I like the fact that units are illustrated in the formulas. This manual is simple to read, the illustrations are great, and the order of the experiments matches how I conduct the lab."--Mohamad Mustafa, Savannah State University
