Book Description
The pavement remaining service interval (RSI) terminology was developed to remove confusion caused by the multitude of meanings assigned to the various forms of pavement remaining service life (RSL). The RSI concept considers the complete maintenance and rehabilitation (M&R) activity of the pavement system and does not simply consider the end of life as promulgated by the RSL philosophy. The goal of this project was to demonstrate and further develop the application of the pavement RSI concept using real data from two State pavement management systems and the Highway Performance Monitoring System 2010+ dataset. Project-level analysis addressed gaps in the network- and strategic-level analyses. The results from the validation efforts support the conclusion that the RSI represents a valid approach to determining and communicating future M&R needs of a pavement instead of defining pavement life using a single number as in RSL. Those results also show that RSL is essentially not related to the time until the next pavement treatment in an optimal strategy.

Book Description
Many important decisions are necessary in order to effectively provide and manage a pavement network. At the heart of this process is the prediction of needed future construction events. One approach to providing a single numeric on the condition of a pavement network is the use of pavement remaining service life (RSL). However, many issues exist with the current RSL terminology and resulting numeric that complicate proper interpretation, interagency data exchange, and use. A major source of uncertainty in the current RSL definition is the use of the term "life" to represent multiple points in the pavement construction history. The recommended path to consistency involves adopting terminology of time remaining until a defined construction treatment is required (i.e., RSL is replaced by remaining service interval (RSI)). The term "RSI" has the ability to unify the outcome of different approaches to determine needs by focusing on when and what treatments are needed and the service interruption created. This report presents the framework for replacing the current RSL terminology with one based on more exact construction event terms. A companion document (FHWA-HRT-13-050) provides step-by-step guidelines for implementing the RSI terminology.

Book Description
Pavement and Asset Management contains contributions from the World Conference on Pavement and Asset Management (WCPAM 2017, Baveno, Italy, 12-16 June 2017). For the first time, the European Pavement and Asset Management Conference (EPAM) and the International Conference on Managing Pavement Assets (ICMPA) were joining forces for a global event that aimed not only at academics and researchers, but also at practitioners, engineers and technicians dealing with everyday tasks and responsibilities related to transport infrastructures pavement and asset management. Pavement and Asset Management covers a wide range of topics, from emerging research to engineering practice, and is grouped under the following themes: - Data quality and monitoring - Economics, political and environmental management, strategies - Deterioration models - Key performance indicators - PMS-case studies - Design and materials - M&R treatments - LCA & LCCA - Risk and safety - Bridge and tunnel management - Smart infrastructure and IT Pavement and Asset Management will be valuable to academics and professionals interested and/or involved in issues related to transport infrastructures pavement and asset management.

Book Description
The issues and the setting of common engineering criteria to establish threshold values for a better calculation of the pavement distress indices and Remaining Service Life (RSL) are presented. Benefits derived from the use of RSL such as simplifying the Pavement Management System (PMS), computational procedures, improving communication between the various PMS users, and increasing the PMS capability are also included. Within the framework of a PMS, most State Highway Agencies (SHAs) collect pavement condition data to calculate pavement distress indices. Because pavement condition data is the basis for all PMS analysis, the values of the pavement indices are typically prioritized and the highest priority is placed on eliminating most deficiencies. Examination of this effort has indicated that the method is deficient and that the RSL is a better pavement condition index.

Book Description
Pavement management is a process that helps to maintain a pavement network in a safe and serviceable condition in a cost effective manner. A key component of an effective pavement management system is its ability to predict the remaining service life of pavements. Remaining service life of pavements can be predicted using the present pavement condition and the latest rehabilitation action performed on that particular pavement. Survival curves are often developed to obtain remaining service life of a pavement family. The objectives of this study are to determine the average service life of pavements and to predict their remaining service life. Remaining Service Life is defined as the projected number of years until rehabilitation is required. The pavement condition data in the form of Pavement Condition Rating (PCR) were used to develop Kaplan-Meier survival curves for different PCR thresholds. PCR 60 was considered as the terminal condition and the average service life of pavement network was calculated as the area under PCR 60 survival curve. Derived performance curves for all the survival probabilities were developed between pavement age and PCR using the Weibull approximation of the Kaplan-Meier survival curves. Derived performance curves were employed to determine the remaining service life of individual pavements based on current age and PCR. PCR curves were also developed for individual PCR thresholds between RSL and pavement age by using the Weibull approximation of the Kaplan-Meier survival curves to better understand the relationship between RSL, PCR and pavement age. Average service life of the pavement network and remaining service life of individual pavements obtained from this study can be used to assist in pavement rehabilitation decision making and budget allocation.
