Grissom Air Reserve Base Runways Project

This project is a renovation of approximate total mill and overlay is 3,290,000 square feet and approximate total full depth replacement is 471,000 square feet of PCC. The proposed project includes: Repair throats at Taxiway C to full depth. Conduct a repair of the north and south Taxiway C throats by removing all layers of pavement at full depth to subgrade and replace with Portland cement concrete (PCC). Repair Taxiway G sections. Remove the asphalt over Portland cement concrete (APC) at full depth to subgrade and replace with Portland cement concrete. Repair full length of Runway 12,501ft using mill and overlay and full depth PCC methods as designed. Variable Mill of surface and overlay with asphalt concrete (AC). Repair 1,200LF to full depth with PCC. Repair shoulders for the entire length of the runway (12,501ft) by variable milling of surface and overlaying with asphalt concrete. Repair the asphalt concrete paved overruns at the 23 and 05 ends of the runway by milling the surface and overlaying with asphalt concrete. Repair by replacement of airfield lighting circuits the (1) complete approach system for runway 05 (2) the threshold light bar at the end of runway 23 (3) feeder cables from home runs at both 23 and 05 ends (4) Taxiway G edge lighting (5) airfield guidance sign system.
