THE SINGAPORE PAVEMENT MANAGEMENT SYSTEM

A rational approach to road maintenance management has been achieved in Singapore through the introduction of a network based Pavement Management System (PMS). Engineers from the Public Works Department are currently using the PMS to plan and control maintenance activities in 2,780 kilometres of road in a predominantly heavily urbanised environment. This paper describes the main features of the PMS. A relational database management system is used to organise the data and present it in a user- friendly way. Great emphasis is placed on the use of objective pavement condition data collected in a continuous manner throughout the road network using the Deflectograph, SCRIM and High- speed Road Monitor. The pavement condition data is used in conjunction with performance models to predict the future condition of the network in terms of structural, skidding resistance and riding quality. Automatic procedures use the trended survey data together with user defined intervention levels to identify road and junction maintenance schemes and to rank them into priority order. Iterative procedures enable the user to rapidly undertake consequential budget analyses over a user defined budget period. For the covering entry of this conference, see IRRD abstract number 843191.
