| Summary: | Currently, most of the slope failure occurred in highways due to inadequate design and lack of maintenance to address current situation. Slopes failures along the highways in Malaysia have been occurring and can be considered as an unpredictable event. One of the good examples is slope failure, which happened in 1996 at KM 303.80 (South Bound) near Gua Tempurung, Perak. The objective of this research is to identify the type of defects that contribute to the slope failure, identify and establish the common failures at various slope angle and to identifY common type of slope repair in Malaysia.. Literature review and case study has conducted to achieve the objectives .Based on the case study that has been carried out, there are few types of defects that contribute to the slope failure such as water seepage and collapsed drain. In this case study, slope failures also occurred due to slope angles and height. Stone pitching and rockfill were identified is a common method type of slope repair in highway. A few recommendations need to be addressed by the designers or client when they intend to design a new slope along the highway such as type of vegetation, type of drain, accessibility, etc. In considering all these factors, it will benefit to the owner or client in term of maintenance cost in future. In conclusion, Asset Management has played an important role in future not only for slope along the highway but to other assets such as building, tower, etc. in order to maximize the company profit. |
