Abstract
The need for an accepted worldwide standard configuration of falling weight deflectometer (FWD) testing equipment used for airport runway pavements is highlighted in this paper. The data provided by the FWD equipment can have a significant effect on airport pavement design and maintenance programs. The major FWD equipment configuration parameters affecting the measured deflection basins include the load levels, load plate size, and load pulse duration. This paper summarizes the results from FWD tests performed on flexible pavements to study the uniformity of pavement structures at the National Airport Pavement Test Facility (NAPTF). The data was analyzed to study pavement structure uniformity, relationship between the sensor responses and load, and relationship between sensor response and load pulse duration. For the covering abstract see ITRD E118503.
