Investigating the impact of preventive maintenance treatment practices on pavement performance

Pavement maintenance strategies have become as a significant study field in the 21st Century. Maintenance practices are defined as all procedures that can be taken to resolve all possible deterioration forms. This paper basically attempts to examine the relation between preventive maintenance treatment practices and the overall performance of pavement. The researcher followed the descriptive method through reviewing various studies and researches in this field. The study clarified is that there are several classifications of pavement types and the main types are (Flexible and rigid) pavements. The study also clarified that there are various factors influenced the overall pavement performance, such as construction quality, moisture level, subgrade, traffic load and maintenance. The main results of this study is that adding the proper type of maintenance in the right time could lower the expected rehabilitation cost, and enhance the pavement efficient performance. The preventive maintenance is a basic maintenance practices that are considered as a cost-effective rehabilitation and enhance the pavements operational life.
