Runway 13-31 was plagued by climate-related cracking that had progressively worsened over the previous few years. Given four different design options, the Airport decided to apply an unbonded PCC overlay over the existing flexible pavement. This design option was able to utilize the strength of the existing soil conditions and asphalt runway as the subgrade and subbase. It also ensured positive transverse drainage. The scope of work included crack repair and sealing, full-depth slab replacement, cold milling, joint sealing, installation of pavement markings, installation of new underdrains, and removal and reinstallation of the electrical system—including runway edge lights, taxiway edge lights, threshold lights, guidance signs, and runway end identifier lights.
