This 1976 research study presents a rational application of empirical methods of estimating the driving resistance of prestressed concrete, steel and timber piling into the recent alluvial soils of Oregon, through the use of the Standard Split-Tube Sampler and an Oregon Miniature Pile testing tool. Blow counts obtained from the driving of the testing tools ('N' and 'M' designations) at varying depths in the foundation investigative work are correlated against the ton per foot driving resistance ('R'), as determined by the Engineering News Record formula and its modifications, in 3717 tests on piling driven on Oregon State Highway Division bridge projects in most of Oregon's 36 counties. The correlation is accomplished through a computer-plotter presentation of both the investigative and project data in the form of 20 Resistance Charts of pile type versus Unified Soil Classifications. An example of the use of the Resistance Charts in the estimate of pile lengths for Oregon State Highway bridge projects is included.
