Comparison Between Falling Weight Deflectometer and Static Deflection Measurements on Flexible Pavements at the National Airport Pavement Test Facility (NAPTF)
Pavement surface deflection basins provide valuable information for the structural evaluation of flexible pavements. The pavement surface deflections are easily measurable compared to other responses, such as stresses and strains, and are the basic response of the pavement structure to the applied load. It is frequently used as an indicator of the load-carrying capacity of the pavement. Surface deflection measurements are rapid and nondestructive. Falling weight deflectometer tests and static load tests (using the National Airport Pavement Test Facility test vehicle) were performed on the multidepth deflectometers in the flexible pavements at the National Airport Pavement Test Facility before the start of traffic tests. The falling weight deflectometer is an impulse-type testing device that imparts a transient load on the pavement surface, and the duration and magnitude of the force applied is representative of the load pulse induced by an aircraft moving at moderate speeds. Static load tests are more representative of stationary or very slow moving aircraft. The National Airport Pavement Test Facility has nine pavement test items and 10 transition sections built on three different subgrades (California Bearing Ratio of 4, 8, and 20).
