Abstract: Initial characterization of rock material usually uses index tests. Mechanical properties of rockfill can be predicted on the basis of strength of irregular lumps. The use of the point load test for this purpose, as an alternative to the crushing test normally used in Portugal, is investigated. Results of tests on granite and greywacke indicate that the two tests are related. The point load test, which is portable, rapid, and simple, is therefore recommended for initial testing of potential rockfill materials.
