Long-Term Performance of Warm-Mix Asphalt Overlay on an Airport Major Taxiway: Case Study

Warm-Mix Asphalt (WMA) technology allows for lowering the production and placement temperature of the asphalt mix relative to conventional practices. WMA technology has been used in Europe since the 1990s and has gained acceptance in the US by State Highway Agencies since the early 2000s. Despite the environmental and cost benefits, very little work has been performed to implement WMA on airport infrastructure. This paper summarizes the construction and testing performed on test sections containing polymer-modified binders, Sasobit® wax additive and recycled asphalt pavement in the mix that were paved on Taxiway ‘A’, a high-volume taxiway at Logan International Airport in East Boston, Massachusetts. Levels of oxidative aging in asphalt mix samples collected from the surface were analyzed in-situ using a Diffused Reflectance Fourier-Transform Infrared spectroscopy technique. The oxidation levels were then related to volumetric parameters of the WMA mix and distresses accumulated over the eight years of service. Testing and the field survey show no significant differences between the various WMA test sections, suggesting minimal impacts of incorporating Sasobit as a WMA modifier to a top course of airfield pavement containing polymer modification and/or low levels of recycled asphalt pavement.
