Evaluation of selected airport pavements in New Mexico
Rehabilitation of poor conditioned airport pavements can be very expensive compared to the rehabilitation of relatively good conditioned airport pavements. Determining the conditions of airport pavements is a first step to determine appropriate rehabilitation method and timing. In this study, the …

Evaluation of FWD software and deflection basin for airport pavements
… software to obtain modulus of layer materials of airport pavements. Currently, several backcalculation software are available. However it is not known which software produces accurate and consistence modulus values. In this study three backcalculation software; namely, BAKFAA, EVERCALC, and …

Nondestructive Evaluation/characterization of Airport Pavements Using Stress Wave Methods
Energy-related processes in engineering systems and materials are numerous and may collectively describe most meaningful mechanical and physical features of the material/system. Those features may be retrieved using single, or ensemble-averaged, impulse-generated NDE tests using the methodology …

Alternatives to PCI and MicroPAVER based maintenance solutions for airport pavements
Airport pavements need to be maintained for adequate health condition by implementing cost effective maintenance solutions. Traditionally, maintenance and repair techniques have been developed based on the minimum acceptable Pavement Condition Index (PCI). However, there are pavements which show …

Analyses and prediction of granular layer rutting trends in airport pavements due to heavy aircraft wheel loading and wander patterns
… Aviation Administration’s (FAA’s) National Airport Pavement Test Facility in New Jersey. Referred to herein as the Construction Cycle 5 (CC5) experiment, CC5 sections were built with different subbase materials (crushed quarry screenings and dense graded aggregates) with varying thicknesses …

Investigation of the performance of flexible pavement systems under moving loads using finite element analyses
… current design methods inadequate for airfield pavements. In addition, airport pavements experience significant wander. However, the effect of wander on airport pavement performance has not been evaluated. In previous studies, the stress interactions between each tire of a triple-dual-tandem …

Three-dimensional finite element modeling as a tool for flexible pavement design and analysis
… the aircraft landing gear determined that pavements with less than 30 inches of pavement structure over the subgrade will result in high levels of stress on the subgrade and adding additional subbase has diminishing returns in improving the pavement performance. The elastic response of the …

Influence of moving load, structure, temperature gradient, and wheel configuration on load transfer efficiency
An airport pavement consists of one or more paving materials over the natural subgrade. Pavement design involves the interaction of pavement with vehicular loads and climatic conditions. The Federal Aviation Administration (FAA) uses a mechanistic design procedure, FAARFIELD, for the design of …

Implementation of mechanistic-empirical approach for structural design of hydrated lime modified flexible pavement
… maintenance, and rehabilitation of highway and airport pavements has been recognized for many years. Mechanistic methods are based on the principles of mechanics in contrast to the particular purpose and empirical procedures that are often used.The objective of this study is the development of …
