The problems of slope instability can be related to the terrain factors and weather. In Malaysia, slope failures and landslides are very common due to prolonged monsoon rainfalls. The consequences of slope instability can be hazardous to life including economic damages and costly repairs. The study was aimed to determine the physical and mechanical properties of the rock slope material from selected sites. Several tests including field observations were performed to analyze the engineering characteristic and physical properties of this Schist rock slope and Granite rock slope. The rock samples were classified into various weathering grades based on variations in these properties. Scan line methods were applied to obtain the measurement data. Direct discontinuity surveys were carried out in interval of 10 m. Laboratory tests on the samples were done that include two cycles of slake durability, Schmidt hammer test, point load test, petrography test, density test and direct shear box test. The analysis on each rock types showed that the amphibolite Schist at Putrajaya has the highest rock strength with a uniaxial compressive strength (UCS) 487.97 Mpa which is classified as extremely strong rock. By comparison, the UCS value of Granite was 267.28MPa and classified as strong rock.
