Author Description

Field Manual (FM) 5-472, "Materials Testing," provides the technical information necessary for military personnel to obtain sample 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 of their use in military construction. This manual covers soils, aggregates, bituminous cements, bituminous paving mixtures, Portland-cement concrete, and stabilized soils 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 test results. The manual explains methods for designing bituminous paving mixtures and for stabilizing soil. It also gives the procedures and tests required to control the manufacture of these mixtures. The manual describes the tools and equipment for performing these tests and contains general instructions for the care, calibration, and use of test equipment.
