21 Methodology Phase 1 Conducted extensive literature review Queried many states for information on what they did and how long it lasted. Analyzed the LTPP Database for treatment approaches and performance. Where the LTPP data did not have sufficient performance history, ran numerous PerRoad and MEPDG design analyses to estimate service life for a range of LTPP sites. 21

22 Methodology Phase 2 Visited seven agencies to review what they did, how it performed (site visits) and worked with them to help develop the guidelines and provide feedback on the Guidelines. Developed test cases and conducted a number of workshops to review and refine the guidelines. 22

23 Long Life Approaches Unbonded PCC overlays of flexible pavement Unbonded PCC overlays of rigid pavements Bonded CRCP overlays of CRCP HMA overlays of rigid pavements With rubbilization of PCC pavement With crack and seating of JPCP With saw crack and seating of JRCP HMA overlays of flexible pavement Provided all stripping, fatigue cracking, thermal cracking is addressed 23

24 Addition of options from R05 & R21 24

25 Decision Matrix: Multiple Selection Tables Selection tables a function of existing pavement type, distress types and levels, and subgrade support renewal options. 25

26 Decision Matrix: Design Tables Design tables were developed to provide an estimate of pavement thickness required for long life pavements. 26

47 HMA Overlays over Existing HMA Pavements Criteria for Long Life Potential The surface condition is good and the structural capacity of the existing AC pavement is adequate for a potential long-life pavement. There is no evidence of stripping in any of the existing HMA layers (determined through coring and/or GPR testing). Proper repair and surface preparation is provided for the existing surface layer, and a good tack/bond coat is provided. The existing drainage system is in good working condition, or adequate drainage is provided. 47

56 R23 Early Use Case: WSDOT WSDOT used R23 products on a time sensitive project on Interstate 5 to help identify the best long-term renewal approach for the agency. Performed Pavement Assessment Formal designs and thicknesses were comparable to that of the R23 Pavement Guidelines so felt confident Used R-23 Guide Specs to help shape specs for project Final design resulted in crack, seat, overlay over existing PCC. 56

57 State of the Practice Value: WSDOT WSDOT used R23 products on a time sensitive project on Interstate 5 to help identify the best long-term renewal approach for the agency. It helped us identify our renewal options, understand how to specify them, and define best practices for implementation, without stumbling through several weeks of analysis Jeff Uhlmeyer State Pavement Engineer 57
