This text investigates the application, interpretation, and standardization of cone penetration testing (CPT) as a primary tool for site characterization in geotechnical engineering. The authors, recognized experts in soil mechanics and in-situ testing, synthesize decades of field data and empirical research to provide a rigorous framework for evaluating soil behavior. They argue that CPT provides a more continuous and reliable profile of subsurface conditions compared to traditional sampling methods, provided the practitioner adheres to established calibration and analysis protocols.

Experts in the field identify this work as a foundational technical manual for geotechnical practitioners and researchers. Readers frequently note the high density of empirical data and the necessity of the text for professional site investigation workflows.
