This three-hour course discusses criteria and methods for improving soil characteristics by the alteration or modification of one or more of soil properties for improved performance of roads and airfield pavements. Stabilization can be used for sub-grade materials ranging from expansive clays to granular materials. A wide selection of processes and materials is available for the engineer. The course will describe the types of available additives used for different types of soil, the quantity to use, and the methods of construction used to blend the additives and soil. Soil additives discussed here include portland cement, lime, flyash, bitumen, and combinations of two or more of these additives. You are required to study the following Technical Manual: Soil Stabilization for Pavements TM 5-822-14/ AFJMAN 32-1019 of the joint departments of the Army and the Air Force (1994 edition, 57pages).
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
