FL DOT Study: GNV Airport Runway Pavement Preservation

This report presents a comprehensive technical assessment of the maltene-based pavement rejuvenation program applied to Runway 7/25 at Gainesville Regional Airport (GNV). Drawing on FDOT State Materials Office performance monitoring data collected over a five-year period (2016–2021), core extraction viscosity data from the GNV pavement, and Dynamic Shear Rheometer (DSR) results from the Colorado State Highway South 109 project (APART Report 26-0207), this study evaluates friction performance, cracking resistance, binder rheology, Foreign Object Debris (FOD) risk, and Life Cycle Cost economics for both aviation and highway DOT applications.

Executive Recommendation

  • Adopt maltene-based rejuvenation (JointBond/Reclamite) as a primary preservation strategy for Runway 7/25 subsequent treatment cycles and for all applicable FDOT DOT assets.
  • Schedule an Initial Treatment (Year 1) with a Secondary Extension (Year 6) per the Best-Practice Maintenance Schedule detailed in Section 7.
  • Deep penetration confirmed to 1–2 inch depth in GNV cores validates superior FOD resistance versus surface-only sealants.
  • All sections remain above FAA Mu = 0.82 threshold after five years, confirming aviation safety compliance.
  • Estimated ROI: 3–5 year service life extension per treatment cycle, yielding 15–25% overall pavement life improvement.

The most complete economic case is made by evaluating the total cost of a coordinated preservation program — JointBond applied to all longitudinal joints and Reclamite applied full-width — against the Do Nothing alternative in which no proactive treatment is undertaken until full mill and 3-inch overlay with joint mill and inlay is required. The preservation program requires only 4 total treatment events (2 JointBond + 2 Reclamite base) over the evaluation window vs. 1 catastrophic full-width mill and overlay event under Do Nothing — the preservation path is both cheaper and operationally less disruptive
