Slope Stability in Road Construction: A Guide to the Construction of Stable Roads in Western Oregon and Northern California

This booklet presents a general outline of the geology of western Oregon and nothern California to provide a background for discussion of specific problems of road construction. Basic slope stability is illustrated by a description of the balance of forces that exists in undisturbed slopes, how these forces change as the road is constructed, and how ground water affects slope stability and causes road failures. The final section of this publication discusses techniques for constructing stable roads on specific geologic materials and soils. Several appendices are included which discuss certain concepts in soil mechanics in greater detail togeter with basic techniques in slope stability analysis for those readers who desire this information.
