Reinforced soil walls have been used extensively in Malaysia for the construction of urban highways. The reasons for the popularity are the saving of time, cost effectiveness, aesthetics and minimum disruption to the ongoing vehicular traffic. This paper reports the application, design, material specification and construction of reinforced soil walls for the various urban highways projects in Kuala Lumpur including the Middle Ring Road II project. The challenges faced by geotechnical engineers in dealing with soft ground and limestone geological formation conditions in Kuala Lumpur are also briefly described. The design of reinforced soil walls is explained in detail with particular reference to the British code of practice BS 8006: 1995. The methodology and the sequence of construction are highlighted to illustrate how time is saved and the disruption to ongoing traffic is brought to a minimum. The measures taken to enhance durability, aesthetics and maintenance of the walls are also described. (a) For the covering entry of this conference, please see ITRD abstract no. E214938.
