Slope stability plays a significant role in the planning and execution of many infrastructure projects located on sloping terrains, including dams, highways, and urban expansions. The current study is a comprehensive investigation of slope stability using empirical technique. Slope Mass Rating (SMR) approach commonly used empirical method for determining the stability of rock slopes, as well as its extensions, such as Chinese Slope Mass Rating (CSMR) and Continuous Slope Mass Rating (CoSMR) systems. The investigation focuses on the Ramban district of Jammu and Kashmir, which is known for frequent landslides along National Highway NH-44. To assess the efficacy of these approaches they were applied to fourteen susceptible slopes along the NH portion and their stability was thoroughly compared. The results show that except for one slope (SL-4) SMR values are generally greater than CoSMR values and less than CSMR. The majority of the slopes are categorized as having poor stability (Class IV) by Romana’s classification, with SMR values ranging from 11 to 59, CoSMR values ranging from 3.39 to 74.56, and CSMR values ranging from 16.36 to 54.25. Unstable slopes are largely made of slate and phyllite, whereas moderately stable slopes are made of granitic gneiss. The study emphasizes the importance of specific adjustment factors on slope stability assessments, suggesting that CoSMR is a more sensible and less biased evaluation than SMR and CSMR.
