This unique lab manual guides students step-by-step through the hows and whys of the most commonly used testing methods in civil engineering practice—those based on the latest American Society for Testing and Materials (ASTM) and American Association of State Highway and Transportation Officials (AASHTO) procedures. The manual uses a consistent “Procedure,” “Data,” and “Calculations” format for each test; contains completely worked examples showing the computations required for the analysis and evaluation of the test data collected; discusses what data, results, and other information should be presented in the test report; and explains what the test results will be used for in practical engineering problems. Blank data reporting forms and graph papers are provided for most tests, and an accompanying diskette contains state-of-the-art, user-friendly software for compiling test data, performing calculations, plotting curves, and obtaining final results.
