Application and Validation of Remaining Service Interval Framework to Pavements Through the Use of State Highway Agency Pavement Management Data

Project Information

Project ID: 
FHWA-PROJ-13-0087
Project Abstract: 

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 RSI terminology offers an advantageous replacement for 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 (FHWA) 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:

  • Conduct research and development services to develop detail analysis methodologies for the new Pavement Remaining Service Interval (RSI) concept developed in a recently completed FHWA research effort entitled, 'Definition and Determination of Remaining Service and Structural Life' under Task Order DTFH61-08-D-00033-T-09001.
  • Apply and validate the developed methodologies using a minimum of two SHA pavement management system data. The effort will also use HPMS 2010+ datasets for similar validation for national level analyses.
