Abstract

In the United States, there are more than four million miles of road network and new roads are being constructed every year. Most of the road networks were constructed more than two decades ago. Therefore, the age of the majority of the pavement inventory has exceeded original design life. This results in increased work load for the maintenance division of the state Departments of Transportation (DOTs). To maintain the road system, state DOTs use In-House or outsource maintenance works to private contractors using Method Based Contracting (MBC), or Performance Based Contracting (PBC), or any combination of these three. Literature reviews shows that outsourcing the road maintenance works are increasing every year and some transportation agencies are moving from using MBC to PBC due to various reasons—to improve quality of asset condition, to save cost considering life-cycle cost analysis, to transfer risk to the contractor, to improve road users satisfaction level, etc. To execute the PBC, which is a comparatively newer method, the state DOTs are facing problems identifying implementation issues. Therefore, it is important to prepare a framework for the implementation of PBC method. In this dissertation, two important road maintenance activities, chip seal and striping, were selected to develop the framework. The primary contribution of this dissertation was to develop the framework to guide the transportation agencies to execute the chip seal and striping using performance-based specification. This will help state DOT engineers effectively implement the PBC for chip seal and striping. The framework consists of three phases—contract document preparation, contract procurement, and contract implementation. All the three phases consisted of detailed investigation of works to be considered in the implementation of the chip seal and striping. The framework is developed by conducting a Delphi study with state DOT maintenance engineers and academicians. This dissertation also provides some recommendations for future study so that PBC can be successfully implemented in all road maintenance works.
