This manual provides the technical information necessary for military and other personnel to obtain samples and perform engineering tests and calculations on soils, bituminous paving mixtures, and concrete. These tests and calculations are required to achieve proper design with these materials and adequate control over their use in military and other construction. This manual covers soils, aggregates, bituminous cements, bituminous paving mixtures, Portland cement concrete, and stabilized soil including stabilizing agents such as bitumens, cements, lime, fly ash, and chemical modifiers. The manual gives detailed instructions for taking adequate representative test samples and step-by-step procedures for making physical properties tests and for recording, calculating, and evaluating the test results. The manual describes the tools and equipment for performing these tests and contains general instructions for the care, calibration, and use of test equipment.
