CHAPTER 12 PAVEMENT PRESERVATION GUIDELINES PAVEMENT PRESERVATION PROJECT SELECTION GUIDELINES The Pavement Preservation Guidelines herein are to be used for Federal-aid and 100% state-funded projects as applicable. Preservation strategies for interstate/freeway sections should be developed to incorporate Pavement Preservation work at appropriate intervals to maintain the pavement throughout the design life of the roadway. See Chapters 11 and 13 for plan requirements. Districts must have an overall interstate/freeway plan developed for each year of their four-year program. This plan should be developed and formally documented using the Roadway Management System (RMS). Programmed and executed Pavement Preservation work, including work such as Maintenance Contracts, must also be included in the District's overall interstate/freeway program. Formal documentation of the work completed on the subject highway systems in the RMS's Pavement History database is essential to the planning and programming effort. PAVEMENT PRESERVATION PROJECT CRITERIA Refer to the memo in Chapter 12, Appendix A, FHWA Pavement Preservation Memorandum from FHWA dated September 12, 2005 for Pavement Preservation definitions. Also defined are the components of Pavement Preservation. AASHTO's Standing Committee on Highways defines preventive maintenance as the planned strategy of cost effective treatments to an existing roadway system and its appurtenances that preserves the system, retards future deterioration, and maintains or improves the functional condition of the system (without increasing structural capacity). Typical Pavement Preservation Treatments. Flexible Pavement Treatments: Asphalt Rejuvenators Asphalt Sealers Crack Sealing Crack Filling Scrub Seals Sand Seals Chip Cape Seals Slurry Seals Micro Surfacing Profile Milling Ultra-Thin Friction Course (generally 3/4 inch) ≤ Thin Overlays (non-structural, generally 2 inches) ≤ Mill & Resurface (non-structural, generally 2 inches) ≤ Ultra-Thin Bonded Concrete Overlay of Asphalt (as a non-structural wearing course) Hot In-place Recycling Cold In-place Recycling Rigid Pavement Treatments: Crack Sealing
