Point load testing is used to determine rock strength indexes in geotechnical practice. The point load test apparatus and procedure enables economical testing of core or lump rock samples in either a field or laboratory setting. In order to estimate uniaxial compressive strength, index-to-strength conversion factors are used. These factors have been proposed by various researchers and are

Abstract. Strength is an important engineering parameter for determining excavatability and load bearing characteristics of rock. Because of the low test cost, it is desirable to identify a multiplier relating the Point Load Test Strength Index (I s(50)) with strength derived using the more expensive Uniaxial Compressive Strength Test.Samples from eight test locations on the Sunshine Coast
