Incorporating Pavement Management into the LRTP

1. Incorporating Pavement Management into the LRTP John Kiefer, P.E.Research Engineer Center For Technology and Training Michigan’s Local Technical Assistance Program Transportation Institute

4. Long Range Transportation Plan What component is commonly missing? Network Level Metrics!!!

5. Roads as an Asset

6. Window of Opportunity Condition Rating Excellent Preventative Maintenance Heavy Maintenance Light Rehabilitation Heavy Rehabilitation CDP Asset Replacement Poor Time

7. Managing Physical Assetsthe Nuts & Bolts Steps • Inventory • Condition (rating) • Predicting future condition • Managing network

8. Inventory – What do I own? You can’t manage what you don’t know you own

9. PASERPavement Condition Rating PASER – Pavement Surface Evaluation and Rating Visual survey—based on sound engineering principles Measure of surface distress Scale of 1-10

10. Predicting the Future • Rules of thumb • Past experience • Professional opinion • Model historical rating data

11. Future Condition What will happen tomorrow?

12. 4. Network Level Measure • Service Cycle • Management System - RoadSoft • Historical distribution • NCPP Network Health • National Center for Pavement Preservation

13. Network Level Vs. Project Level Project: Moving pieces Network: Winning game

14. Service Cycle • How big is the network? • How much of the network do I do work on? • How long will it take to “touch” the entire network? • Is this longer than the expected life of my pavement? • EXAMPLE • 500 lane mile road network • Do 10 lane miles of work each year • Takes 500/10 = 50 years to touch all of the network • Asphalt pavement only last 15 years

18. NCPP Network Condition Health • # Of Lane Miles in your network • Same number of RSL lost each year • How it works . . . • Programmed Activity (reconstruction, chip seal, etc.) • Fix Cost (per lane mile) • Extended Service Life (ESL) • # of Lane Miles Fixed • Result • Lane Mile Years per Fix • Total for Entire Network

19. NCPP Network Condition HealthMI Example—625 Lane Mile Network 204 $3,732,800

20. NCPP Network Condition HealthGroup Exercise 625 Lane Mile Network $3,732,800 maximum budget Treatment candidate available lane miles • Reconstruction = 150 lane miles • Rehabilitation = 100 lane miles • Mill & Overlay = 115 lane miles • Non Structural Overlay = 80 lane miles • Crack Seal = 100 lane miles
