Abstract:
The largest airport in Houston, TX, George Bush Intercontinental Airport (IAH), underwent a major expansion to accommodate increasing amounts of air traffic. Part of this expansion included the development of a 10,000-ft-long (3000 m), 150-ft-wide (46 m), 18-in.-thick (460 mm) runway. Runway 15R-33L, which was open to air traffic on June 13, 2002, is noteworthy because it was built using a ternary blend concrete. The composition of the new concrete runway includes 25% Class F fly ash by mass of cement, 25% slag by mass of cement, and only 50% by mass Type I portland cement. The primary purpose of this article is to report on the material properties and performance characteristics of this concrete, while discussing the runway’s enhanced durability.
