This course discusses the soil stabilization methods for pavements. A well stabilized soil is essential for the proper function of our roads, bridges, dams, and runways. Due to the non-homogenous nature of soil, it is common to find soils of different types, stability, compaction, and moisture content within one project. And though soil stabilization occurs during the first stages of a project, it can determine the life of a structure. This course therefore provides useful and relevant information for designers, contractors, and owners of pavement projects both large and small.
The course identifies criteria for improving the engineering properties of soils used for pavement base courses, subbase courses, and subgrades through the use of additives, which are mixed into the soil to effect the desired improvement. When added to the soil in the proper quantities, additives can improve soil strength, texture, workability, and plasticity. Chemical additives such as portland cement, lime, fly ash, and bitumen will be discussed. The course also covers several testing methods and American Society for Testing and Materials (ASTM) standards, enabling students to determine the best form of soil stabilization for a broad spectrum of applications.
The student must take a multiple-choice quiz consisting of thirty (30) questions at the end of this course to earn PDH credits.
