Rock slope kinematic analysis and rock mass classifications has been conducted at the 17^(th) km to 26^(th) km of USAID(United States Agency for International Development)highway in *** research aimed to examine the type of rock slope failures and the quality of rock mass as *** scan-line method was performed in six slopes by using a geological compass to determine rock mass structure on the rock slope,and the condition of joints such as persistence,aperture,roughness,infilling material,weathering and groundwater *** kinematic analysis was performed employing a stereographic *** rock slope quality and stability were investigated based on RMR(rock mass rating)and SMR(slope mass rating)*** rock slope kinematic analysis revealed that planar failure was likely to occur in Slope 1,3,and 4,the wedge failure in Slope 1 and 6,and toppling failure in Slope 2,5,and *** RMR rating is ranging from 57 to 64 and can be categorized as Fair to Good *** SMR rating revealed that the failure probability of Slope 3 was 90%,while it was from 40%to 60%for *** the uniform RMR for all slopes,the SMR was significantly *** detailed quantitative consideration of orientation of joint sets and geometry of the slope contributed to such differences in outcomes.
