John Poullain, PE
This five hour online course covers the latest methods for planning a geotechnical exploration for road pavement projects. The course provides guidelines for a well-planned exploration program including sampling and testing issues and the exploration requirements for borrow and subgrades. It reviews the geophysical methods, FWD, SR, GPR, EM, their advantages and disadvantages. It discusses the characterization of existing and constructed subgrades, base and subbase materials. Problem subgrade soils such as expansive soils, and frost susceptible soils are discussed. A flow chart outlines the steps in planning a geotechnical investigation.
It has been shown that a majority of all construction claims were related to inadequate subsurface information. The design of a pavement, subgrade, excavation, and fill requires an understanding of soil strength; soil characteristics and consideration of problem soils and how soil behaves under imposed wheel loads. The course discusses the influence of geotechnical inputs of pavements with respect to methods and techniques used for subsurface exploration. How the locations and number of borings and samples are selected and types of exploratory methods employed is discussed.
Among the topics covered in this course include:
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
