  1. Lecture 14 REMAINING SERVICE LIFE

  2. Instructional Objectives • Concept of remaining service life • How remaining service life is used and its importance • How remaining life is calculated

  3. Introduction • RSL: definition • Analysis - Step 1: determine RSL for each pavement section - Step 2: examine how RSL distribution in network can be changed

  4. Developing an RSL Analysis • Define threshold values • Develop condition indices • Develop performance curves • Define RSL categories • Define RSL cost matrix • Define RSL construction effort matrix

  5. Defining RSL Categories • Category I: RSL = 0 • Category II: 0 < RSL  5 • Category III: 5 < RSL  10 • Category IV: 10 < RSL  15 • Category V: 15 < RSL

  6. Example RSL Cost Matrix

  7. Example Construction Effort Matrix

  8. The RSL Analysis • Calculate RSL for each section • Show RSL distribution on network • Predict future RSL distribution • Apply different levels of effort and examine effects on future RSL distribution

  9. Calculating the RSL for a Pavement Section

  10. RSL Distribution

  11. Calculating the Future RSL

  12. Example Future RSL Distribution • Assume the cell ‘EII-V’ equals 10 in the Construction Effort Matrix

  13. Practical Considerations • RSL reliability is function of reliability of condition survey and performance curves • Future RSL distributions are network level not project level

  14. Future Trends • Sophisticated PMS “carries along” RSL calculations with life-cycle cost • RSL distribution a result of PMS analysis

  15. 5-Year Analysis

  16. Summary • Definition - RSL • RSL Analysis Requirements

  17. Instructional Objectives • Concept of remaining service life • How remaining service life is used and its importance • How remaining life is calculated
