Abstract
A portable tilting table can determine the friction angles of smooth surfaces of discontinuities for the assessment of rock slope stability. The lower bound of tests on sandstones is close to the upper bound of results from surfaces lapped with #80 grit, which give basic friction angles. Siltstones and shales can also be tested at the site when specimens may not survive transportation to the laboratory.
