Manual on Subsurface Investigations

The primary purpose of geotechnical subsurface investigations in transportation projects is to collect data that will help transportation engineers and planners identify, assess, and address risks associated with subsurface conditions; select appropriate design parameters; and monitor performance during construction and operation phases of a project’s life cycle. The results of the research performed for NCHRP Project 21-10 have resulted in a complete revision and update to the 1988 American Association of State Highway Transportation Officials (AASHTO) Manual on Subsurface Investigation that reflects the changes in the approaches and methods used for geotechnical site characterization that the geotechnical community has developed and adopted in the past 30 years. The updated manual provides information and guidelines to help geoprofessionals plan and execute a sound geotechnical site investigation program; use the results to develop a ground model for planning, design, construction, and asset management phases of a project; and report and document the results in a manner that facilitates peer review, communication with stakeholders, and potential future uses.
