Lineament plays major role in stability and strength of rock mass. The presence of lineaments will decrease the strength of rock mass. Lineament can be identified or trace using topographic map, aerial photographs or satellite images. In this research, strength the slope-forming rock mass strength which are affected and non-effected by lineaments was determined by using scan line method. The purpose of this study was to determine the difference of rock mass strength in two difference conditions. A total of 5 rock slopes for each condition were determined. The studied rock slope is located in a former quarry site in Kajang and Sg Long, Selangor, Malaysia. Analysis were done using rock mass rating (RMR). Result of the study show strength of the rock mass which are affected by the lineament is lower compared to those that are not affected by lineament.
