This device is used to calculate the JRC (Joint Roughness coefficient) of a rock joint. It consists of an ad - justable inclined plate, on which the rock sample (maximum 100 mm diameter) is placed, sepa- rated along the surface where the roughness is to be measured. The plate is then slowly tilted until the upper part of the sample starts

For example, a rock with a specific gravity of 2.8 has a unit weight of 28 kN/m 3. The grain specific gravity can be determined by grinding the rock and adopting methods used for soils. Rocks exhibit a large range of density values compared to soils. The density of a rock is easily measured from the volume and mass of a carefully drilled core ...
