Heated Airport Pavements

| 摘要： | Maintaining operational safety and status of airport runways during snowfall events is a challenging issue that many airports are grappling with. According to the Federal Aviation Administration (FAA) Advisory Circular 150/5370-17 (dated 2011), most transport category aircraft are prohibited from operating on runways covered by untreated ice or by more than 1/2 inch of snow or slush, although the limits vary with aircraft types. The surface traction of pavement is dramatically influenced by frozen precipitation in the form of ice, snow, or slush. This can seriously hamper smooth air traffic management operations and cause traffic delays at other airports. Ice and snow on transportation infrastructure systems add significant costs to the American economy via snow removal, damaged pavement and bridge surfaces and lost man-hours due to travel delay. It is imperative that both small and large airports maintain operational status during snowfall events to support the existing operations as well as the FAA's NextGen concept as mentioned in the Airport Technology Research Plan for the NextGen Decade (dated January 2012). This project proposes a 3-pronged approach to investigate the efficacy and cost effectiveness of new heated pavement technologies. The project proposes to investigate: the relative energy and monetary needs to remove snow from a slab by conducting an energy and financial viability analyses under Task 1-A; a hybrid approach combining electrically conductive concrete with lotus-leaf-inspired super-hydrophobic surfaces under Task 1-B; and the application of nano-coatings of low temperature phase change materials with the intent of preventing ice and slush formation under Task 1-C. The project anticipates that these three tasks will run in parallel. |
