“…Although past works (Cullocis-Rio et al, 1984;Fwa and Sinha, 1985;Feighan et al, 1986;Fwa et al, 1988;Sinha et al, 1988;Mouaket et al, 1990;Lamptey et al, 2004, Sinha et al, 2005 allowed the understanding of the issues involved in maintenance and rehabilitation operations and the effects of these on pavement performance, there is still a gap between the integration of pavement preservation and pavement management, especially at the implementation level. This study therefore aims to develop a pavement preservation program framework for INDOT and integrates the various components of pavement preservation at a district and network level.…”

“…Numerous projects have been undertaken to evaluate pavement performance and to better manage the pavement maintenance and rehabilitation processes (Cullocis-Rio et al, 1984;Fwa and Sinha, 1985;Feighan et al, 1986;Fwa et al, 1988;Sinha et al, 1988;Mouaket et al, 1990;Lamptey et al, 2004, Sinha et al, 2005. These works have allowed the understanding of issues involved in maintenance and rehabilitation operations and the effects of these activities on pavement performance; and the ability and tools to better manage pavements at the network level (such as the optimal programming of maintenance and rehabilitation activities).…”

State highway agencies are facing immense pressure to maintain roads at acceptable levels amidst the challenging financial and economic situations. In recent years, pavement preservation has been sought as a potential alternative for managing the pavement assets, believing that it could provide a cost-effective solution in maintaining infrastructural conditions and meeting user expectations.While the concept of pavement preservation is has been established at the project level, there is still a significant gap in implementing elements of pavement preservation at the network level, especially within the pavement management system. Recognizing the need to integrate both project and network level pavement preservation into a coherent pavement management structure, this research study attempts to develop a framework for pavement preservation implementation within the state of Indiana. Several elements related to integrating pavement preservation in a pavement management framework are studied: (i) determining triggers for pavement preservation treatments for use in a PMS, (ii) developing performance models for preservation treatments, (iii) developing a remaining service life approach for strategy comparison at the project level, and (iv) developing a pavement preservation framework that integrates the districts and the central office of a state highway agency. These elements when properly resolved can allow a truly comprehensive pavement management system with consideration to preservation concepts within the Indiana Department of Transportation. FindingsThe first part of the report explores the development of thresholds that allow the "triggering" of preservation and rehabilitation treatments within a pavement management system. Two different procedures to develop intervention levels for pavement preservation treatments are studied. The first procedure involves using historical decisions made by an agency to determine treatment intervention levels, while the second procedure seeks expert opinions to develop relevant treatment decision matrices. Based on the findings presented in the report, distress-based decision matrices are found to be more desirable, primarily because it can be easily adopted for new and innovative pavement materials and preservation treatments.The second part of the report develop pavement performance models (both long term pavement performance and short term performance jumps) for various asphalt and PCC preservation treatments. Costs for preservation treatments are also identified. These models can be used in a pavement management system to allow network level planning and programming of pavement activities.A remaining service life approach for pavement preservation strategy selection is developed to evaluate competing pavement strategies at the project level. An illustration is presented in report to demonstrate the application of remaining service life in project level pavement management. It is found in the report that pavement preservation can be a costeffective solution to preserve our ...

“…During its tenure, Ickes's agency had undertaken six hundred projects in the state, hired thousands of workers, and spent $49 million. 119 To oversee and coordinate state projects, the PWA appointed a state engineer (later called director). George Sager filled that role in Kentucky for most of PWA's active years.…”
