Determination of remaining life of rigid airfield pavement generally involves a combination of engineering judgment and results of discrete test applications on the pavement and subgrade. Fatigue of pavement is almost never directly observed when examining long-term pavement performance of airfields. Observation and detection of distress and response can assist in assessing the remaining pavement life of in-service rigid pavements. In this study, accelerated pavement testing (APT) was employed to assess the remaining life of Runway 16/34 at Fort Worth Meacham International Airport in Forth Worth, Texas. A traffic model was established using reported Federal Aviation Administration aircraft operations. The pavement response, including the impact of fatigue, was observed under super-accelerated pavement (SAP) testing with input from the established traffic model. Investigation of the pavement consisted of two phases. The first phase involved continuous deflection profiles of the entire runway using the Rolling Dynamic Deflectometer (RDD). From the runway deflection profiles, candidate test locations were selected and tested to determine potential test locations outside of the main runway, as operational constraints prohibited testing of the main runway. A comparison of deflection responses was made between Runway 16/34 and the candidate locations. Three test locations adjacent to Runway 16/34 were selected: Taxiway A6, the South Run-Up area, and the North Run-Up area. The second phase of this study consisted of evaluating the remaining life of the rigid airfield pavement using a reconfigured SAP testing application of the RDD, referred to as the Stationary Dynamic Deflectometer (SDD). Nearly 200,000 applications were applied to three independent test points (center, edge, and corner) at each selected test location. Deflection responses were measured and analyzed, resulting in two principal findings.

"TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 433: Significant Findings from Full-Scale Accelerated Pavement Testing documents and summarizes significant findings from the various experimental activities associated with full-scale accelerated pavement testing (f-sAPT) programs that have taken place between 2000 and 2011. The report also identifies gaps in knowledge related to f-sAPT and where future research may be needed. NCHRP Synthesis 433 is designed to expand the f-sAPT base of knowledge documented in NCHRP Syntheses 325 and 235, both with the same title of Significant Findings from Full-Scale Accelerated Pavement Testing. f-sAPT is the controlled application of a wheel loading, at or above the appropriate legal load limit, to a pavement system to determine pavement response in a compressed time period. The acceleration of damage is achieved by one or more of the following factors: increased repetitions, modified loading conditions, imposed climatic conditions, and thinner pavements with a decreased structural capacity which have shorter design lives"--

This compendium gathers the latest advances in the area of Accelerated Pavement Testing (APT), a means of testing full-scale pavement construction in an accelerated manner for structural deterioration in a very short term. Compiling novel research results presented at the 5th International Conference on Accelerated Pavement Testing, San Jose, Costa Rica, the volume serves as a timely and highly relevant resource for materials scientists and engineers interested in determining the performance of a pavement structure during its service life (10+ years) in a few weeks or months.

This thesis develops a complete system for nondestructive testing and evaluation of rigid airfield pavements. An extensive review of present destructive and nondestructive equipment and methodologies is made to form the basis for selection of the equipment and analytical model used in this research. A brief description of the selected Dynatest Model 8000 Falling Weight Deflectometer and the ILLISLAB finite element computer model is presented. Three Air Force installations were chosen for in-depth study of pavement response to FWD loads under a variety of environmental and geological conditions. Techniques are presented to determine the location of maximum damage to rigid pavement slabs for one or any combination of aircraft, and the validity of the calculated stresses is established through comparisons of measured and predicted deflections at joints. Major study findings include: (1) new designations for pavement features based on actual loading conditions, (2) guidelines for planning and conducting large scale evaluations of major airfield systems, (3) a computer-based determination of E and K, (4) joint behavior prediction under fluctuating temperatures and their effect on generated slab stresses, (5) procedures to account for the annual distribution of traffic over the range of temperatures normally experienced at any facility, (6) a simplistic means of estimating total past damage from aircraft operations, and (7) development of computer programs to predict remaining structural life of rigid airfield pavements.

A method for estimating the life of rigid airfield pavements is presented which is applicable for any ty aircraft traffic on all types of rigid pavement including overlays. The basic concept of the method presented is that any rigid pavement will withstand a certain number of stress repetitions before it cracks. The number of stress repetitions is dependent upon the magnitude of stress which is in turn dependent upon such things as: magnitude of load, gear configuration, traffic distribution, pavement strength, and foundation. All are considered in the method presented; an example of the use of the method is shown as well as three classical examples considering special problems. (Author).
