Abstract

The aim of this work is to develop a Pavement Maintenance Management System (PMMS) for the roads and parking network. An extensive review was carried out on previous PMMS projects used for roads in Jordan and other countries. This research focuses on the software called PAVER system that is used to create a comprehensive and integrated database and GIS-based map layers for the road pavement and engineering characteristics. The research will contribute to the provision of a systematic method for the control of the Maintenance and Rehabilitation (M&R) process for paved networks. Although many researches in Jordan discuss reasons and procedures for M&R of road networks, there is still a lack of the systematic strategy and prediction procedure.

7. Conclusions and Recommendations

The research will contribute to provide a systematic method to manage the M&R process of the pavement network. Although, many researchers in Jordan dealt with procedures for M&R of road networks, there is still lack for systematic strategy and prediction procedure. This research will help to provide a model to be adopted by other organizations in Jordan.

During the implementation and application of the PMMS in this study, some challenges were observed. The challenges included the unavailability of historical maintenance records on some sections within the network. In certain instances, it was extremely difficult to verify the available pavement structure layer thicknesses. This would require the need to investigate by trenching techniques or by taking cores of pavements to identify the pavement composition and thicknesses in some areas. Moreover, the application of the new PMMS needs time and effort to implement the new procedures and it requires knowledge and training on the utilization of applicable computer programs.
