ABSTRACT
To provide a cost-effective management of operating funds and maintenance of highway in mountainous terrain, hazard and risk mapping was carried out at the East-West highway. The highway traverses through rugged mountainous terrain situated in the northern side of Peninsula Malaysia with varying geological formations create problems in maintenance and operation. Prior to the mapping study most of the remedial works were executed in an ad hoc manner without the benefit of having an established long term and stability plans. As a result of the mapping work a much more systematic prioritisation of funds from the Government can be allocated to those slopes having high risk of failing. Hazard ratings and factor overlay methodologies were applied to a geotechnical database developed from an intensive field inventory and mapping programme. This paper discusses the mapping approach and the methodology involved in developing a long-term preventive measures and stability plan for highway maintenance.
