Advances in joint roughness coefficient (JRC) and its engineering applications
Journal of Rock Mechanics and Geotechnical Engineering, 2023 The joint roughness coefficient (JRC), introduced in Barton (1973) represented a new method in rock mechanics and rock engineering to deal with problems related to joint roughness and shear strength estimation.

Sustainability, 2022 Accurate determination of the surface roughness is of significant importance in estimating the mechanical and hydraulic behaviors of rock joints. The correlation between joint roughness coefficient (JRC) and various statistical roughness parameters calculated from digitized Barton’s roughness profiles was explored with Pearson’s correlation coefficient

Correlation between Joint Roughness Coefficient (JRC) and statistical roughness parameters [PDF]
Engineering Geology and Geotechnics: Building for the Future, Proceedings of the Conference EUROENGEO 2024Rocks are polycrystalline, heterogeneous, and anisotropic media containing discontinuities that often create planes of weakness. These discontinuities influence the mechanical behavior of the rock mass through their surface morphology, their aperture, and their filling material.
