16. Abstract This document presents state-of-the-practice information on the evaluation of soil and rock properties for geotechnical
design applications. This document addresses the entire range of materials potentiallyencountered in highway engineering
practice, from soft clay to intact rock and variations of materials that fall between these two extremes.
Information is presented on parameters measured, evaluation of data quality, and interpretation of properties for conventional soil
and rock laboratory testing, as well as in situ devices such as field vane testing, cone penetration testing, dilatometer,pressuremeter, and borehole jack. This document provides the design engineer with information that can be used to develop a
rationale for accepting or rejecting data and for resolving inconsistencies between data provided by different laboratories and field
tests.
This document also includes information on: (1) the use of Geographical Information Systems (GIS) and Personal Data Assistance
devices forthe collection and interpretation of subsurface information; (2) quantitative measures for evaluating disturbance of
laboratory soil samples; and (3) the use of measurements from geophysical testing techniques to obtain information on the modulus
of soil. Also included are chapters on evaluating properties of special soil materials (e.g., loess, cemented sands, peats and organic
soils, etc.)and the use of statistical information in evaluating anomalous data and obtaining design values for soil and rock
properties. An appendix of three detailed soil and rock property selection examples is provided which illustrate the application of
the methods described in the document.
