An evaluation of the existing airfield pavements at Dulles International Airport was made in 1978-79 by ARE Inc and HNTB under a contract with the U.S. Federal Aviation Administration (FAA). Field work consisted of condition surveys, nondestructive deflection testing, and materials sampling. Deflections were measured with both the Dynaflect and the heavy load vibrator from the Waterways Experiment Station in Vicksburg. Comparisons of the two types of equipment were made based on various aspects of the pavement evaluation. Laboratory tests were run on the materials and the results were used along with deflection data and aircraft data to select and characterize pavement sections which behave differently under load. Traffic operational data were analyzed to determine the number of past and projected aircraft operations on each section of pavement. A fatigue analysis was then conducted to compute the present remaining structural life and projected end of life for each section. The sections were then grouped into the time periods of 1978 to 1981, 1981 to 1984, 1985 to 1990, and 1990 to 1994 according to their predicted times for reading rehabilitation. (Author)
