Project Description:   The Remaining Service Life (RSL) concept has been around for decades and is well entrenched in the pavement community. It is used at all levels of the pavement management decision process to plan for future field construction events. However, there is no single, clear, and widely accepted definition of RSL. Moreover, there is a great deal of uncertainty associated with the definition, especially with the use of the term “life” to represent different points in a pavement’s construction history. In addition, when communicated, the meaning of “life” is lost and it is interpreted differently by stakeholders. To overcome these deficiencies in the RSL terminology, a recently completed Federal Highway Administration (FHWA) research project titled “Definition and Determination of Remaining Service and Structural Life” under task order contract DTFH61-08-D-00033-T-09001 recommended adaptation of a new terminology of time remaining until a defined construction treatment is required – RSL is replaced by "Remaining Service Interval," or “RSI.” This terminology offers the ability to unify the outcome of different approaches to determining needs by focusing on when and what treatments are needed, and the service interruption created. The reformulated RSI framework is described in a final report and guideline documents titled “Reformulated Pavement Remaining Service Life (RSL) Framework” and “Pavement Remaining Service Interval (RSI) Implementation Guidelines,” respectively. The application of Remaining Service Interval (RSI) terminology offers an advantageous replacement for Remaining Service Life (RSL) in terms of providing additional information as to not only when, but also what, and also to enhance communication. It is critical that the concept be validated through application to real-world problems. To this end, it is desired that the RSI concept be applied to two or more State highway administration (SHA) pavement networks through the use of SHA pavement management data, and its value as a replacement to RSL be critically evaluated. The effort will also use Highway Performance Monitoring System (HPMS) 2010+ data for similar validation for national level analyses. Through these two real-world applications, this effort will also develop and refine the associated RSI analyses methodologies.
Goals:  
The primary objectives of this project are to:
 
(1) Conduct research and development services to develop detail analysis methodologies for the new Pavement Remaining Service Interval (RSI) concept developed in a recently completed Federal Highway Administration (FHWA) research effort entitled, “Definition and Determination of Remaining Service and Structural Life” under Task Order DTFH61-08-D-00033-T-09001.
 
(2) Apply and validate the developed methodologies using a minimum of two (2) State highway administration (SHA) pavement management system data. The effort will also use Highway Performance Monitoring System (HPMS) 2010+ datasets for similar validation for national level analyses.
Product Type:   Research report
Test Methodology:   Development of Remaining Service Interval (RSI) analysis methodologies and data requirements, application, and validation of RSI framework with State highway administration (SHA) pavement management data for SHA network and project level applications, application and validation of RSI framework with Highway Performance Monitoring System (HPMS) 2010+ pavement data for national level application, and development of a step-by-step procedure/algorithm documenting the refined analyses for computerized implementation.
Expected Benefits:   Development of Remaining Service Interval (RSI) analysis methodologies and data requirements and application and validation of RSI framework with State highway administration (SHA) pavement management data for SHA. Development of a step-by-step procedure/algorithm documenting the refined analyses for computerized implementation.
Deliverables:   The deliverable is a final report documenting the entire research effort, findings, and recommendations, including step-by-step procedure/algorithm documenting the refined analyses for computerized implementation of Remaining Service Interval (RSI).
