Rock characterization is one of the most important aspect in rock mechanics. For any work in the rock, on the rock and by the rock a detail rock characterization is must. Various destructive and non-destructive tests are performed to achieve this purpose. The non-destructive tests are being increasingly used for easy, fast and economical characterization of rock mass. The elastic wave velocities, rebound hammer and electrical resistivity are commonly employed non-destructive tests. The sedimentary rocks like Sandstone, limestone and shale are extensively encountered in India for number of infrastructure projects and mining works. Therefore a study of their geotechnical characteristics is imperative in evaluating their response to various in-situ stress and environmental conditions. This paper presents assessment of strength and deformation behavior of three commonly encountered sedimentary rocks viz. Sandstone, limestone and shale through non-destructive tests. The analysis of data indicates that non-destructive tests can be confidently employed for assessment of geotechnical response of rocks particularly for preliminary project planning and designing purpose.
