The concept of overnight construction on runways has been limited to either thin asphalt overlays in nightly segments, replacement of Portland cement slabs with accelerated Type III Portland cements, or calcium sulfoaluminate Rapid Set cement concrete. Thin asphalt overlays have been used frequently with 2-inch (5 cm) lifts that leaves a small grade change that is considered to have negligible effect if using an asphalt ramp that is kept to a maximum of 1-inch per 15 feet (.57% grade). Slab replacements have been relegated to keeping the existing grade because an overlay would be required to be at least 5 inches (13 cm) of concrete. However, what if a rapid setting durable concrete would allow a 6-inch (15 cm) overlay to be constructed at night and opened to traffic in the morning. A ramp would obviously be required, but what would the aircraft response be if a temporary construction ramp of 6 inches (15 cm) was used? Using aircraft simulation, this paper explores the issues of introducing a 1% and 0.5% ramp used for overnight construction and its effect on aircraft response. These ramps will be integrated into three profile types; an artificial “glass smooth” runway, an existing in-service runway with known pavement roughness, and finally, an existing in-service runway with average ride quality. This study identifies parameters that can impact aircraft response: ramp location; profile of the existing surface; and up-ramp vs. down-ramp, etc. The final objective is to provide guidance for the use of temporary ramps that would minimize aircraft dynamic response.
