A COMPARATIVE STUDY OF MONITORING METHODS IN SUSTAINABLE PAVEMENT SYSTEM DEVELOPMENT

Abstract

Pavement management system (PMS) has been receiving increasing attention from both the government and private sectors in the attempt to ensure and keep the roads in good condition. The appropriate level of road maintenance activity is often contingent upon the type of pavement distress. Valid and reliable pavement data would lead to develop a PMS which is more suitable for agencies. Previous studies which attempted to identify modes of monitoring pavements were limited by constraints such as cost, time, and safety. This study was conducted to review some of the pavement monitoring modes introduced in previous studies. After completing a literature review, three mostly used modes, namely manual survey, smart sensor, and optical image processing, are selected for a comparative study to determine which mode is the most effective method in terms of cost, time, safety, accuracy, and sustainability. A data quality guideline was modified to produce a rating system for ranking the modes. In conclusion, the findings of this study could provide a guideline for the government and private sectors in determining the most effective pavement monitoring mode to be used in the sustainable PMS strategy.
