2013 - India - Critical Review of Decision Models for PMS
A primary purpose of a pavement management system (PMS) is to provide information so that roadway improvements can be priority ranked. Ideally, prioritization is a consistent and justifiable process. It should involve minimizing life cycle costs subject to minimum levels of serviceability and budget constraints. Prioritization is a complicated process that requires sound engineering judgment and a good understanding of local conditions. Current fiscal crises and rising roadway improvement costs have made prioritization decisions more important than ever. Priority analysis is a systematic process that determines the best ranking list of candidate sections for maintenance based on specific criteria such as pavement condition, traffic level, pavement functions, etc. Various methods are used for priority analysis ranging from simple listing based on engineering judgment to true optimization based on mathematical formulations.
This paper examines theoretical and pragmatic problems surrounding the prioritization process. This study report a detailed review of various prioritization techniques and models developed for flexible pavements at global level. This will help in evaluating the usefulness of the various models in some particular condition having the similar prioritization parameters. A discussion on the limitations of the different models is also given in this study.
