| Asphalt pavements have a long history of outstanding performance for airfield applications. In 1939, plans were developing to build a National Airport in our nation’s capital.Needless to say, the Asphalt Institute was there working very closely with the Corps of Engineers and other federal agencies to ensure proper design, materials and construction practices were utilized. Upon completion of Washington National in 1940, over one million square yards of airfield were paved with hot-mix asphalt (HMA). While much has changed in both the asphalt and airfield pavement industries over the last 63 years, many things have not. Just as the Asphalt Institute worked with those agencies in 1939 to introduce a relatively new paving material to build Washington National, we are working today with the Federal Aviation Administration (FAA), Army Corps of Engineers (COE), Air Force and Navy to assist them in making a smart transition towards the use of Superpave for airfield pavement. This article discusses the status of that transition, along with some of its challenges, for both the PG Binder system and the Superpave mix design system.  点击浏览该文件 |
