ABSTRACT
Slope stability problems associated with the design, construction and maintenance of roads in mountainous terrain have always received a great deal of attention from geotechnical engineers as well as government agencies. In Peninsular Malaysia, about half of the total land are hilly to mountainous terrain that occupies, mostly the less-developed forested region in the hinterland. During monsoon seasons, a number of cut slopes and fill slopes fail which result in a great amount of money being expended on slope stabilisation and remedial works. This paper presents some experience on methods of stabilisation and remedial works carried out on some failed fill slopes along the East-West highway located in the northern section of Peninsular Malaysia. In order to achieve the most cost-effective solution a comprehensive assessment comprised of surface and sub-surface investigations, design and method of construction are discussed.
