ABSTRACT
Reinforced steep slopes are normally constructed with the utilisation of steel reinforcements and sand backfill. However, the cost of sand and steel strips is relatively high The use of cohesive residual soil and geogrid reinforcement is introduced as alternative to sand and steel strips to cut the overall construction cost. A full scale model of 5 meter high reinforced steep slope was constructed at Nilai Industrial Park to analyze field behaviour of this reinforced slope system. Performance after construction was monitored by incorporating extensive instrumentation including inclinometers, strain gauges, pressure cells, piezometer tubes and surface settlement markers In general, it can be said that this reinforced steep slope has performed satisfactorily since the overall movements and deformations were relatively small during seven months of observation. Drainage system was also working satisfactorily No water was recorded in the standpipe and pnuematic piezometer.
