Maintenance management of pavements for expressways in Malaysia

Abstract

Pavements deteriorate over time due to traffic loading and environmental effects. The maintenance of pavements to improve the riding quality and level of service on major expressways, including the North-South Expressway (850 km in length), is a key challenge for the maintaining authorities and highway concessionaires. Pavement maintenance works not only incur high costs but also cause interruption to traffic flow resulting in complaints from the road users and the authorities. To maintain satisfactory condition of existing pavements, timely intervention is necessary which helps to minimise pavement deterioration and maintenance costs. Pavement condition assessment is required to determine the functional and structural condition which translate into service life. This paper describes an approach with case studies of pavement maintenance management for expressways in Malaysia.
