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.

Six flexible pavements were constructed for construction cycle 7 (CC7) at the Federal Aviation Administration (FAA) National Airport Pavement Test Facility in Atlantic City, New Jersey. Four test sections on the north side measure 200 mm (LFP-4), 250 mm (LFP-3), 300 mm (LFP-2), and 375 mm (LFP-1) that are made of hot mix asphalt (HMA) over an aggregate subbase (thickness varying between 850 and 1,025 mm) resting on a subgrade with a California bearing ratio of 5.5. The fifth test section, LFC-5, is conventional flexible pavement with 125 mm of HMA over aggregate base and subbase, and the LFC-6 structure is the same as LFC-5 except that the crushed stone base layer is replaced with asphalt-stabilized drainable base. The objective of CC7 tests is to develop perpetual pavement design criterion and to validate or refine the fatigue model for HMA in airport pavement thickness design software FAARFIELD. The HMA fatigue model is based on the ratio of dissipated energy change (RDEC). Four fiber optic strain plates were installed to measure transverse and vertical strains at top and transverse strains at bottom within the HMA layer. Full-scale accelerated pavement tests were performed. Traffic test load parameters were six-wheel gear, 245-kN wheel load (gear load 1,470 kN), and 4-kmph speed. Pavement performance was monitored using crack maps, straight edge rut depth, and surface profile measurements. LFC-5 and LFP-4 showed significant fatigue cracks and rutting. LFP-1 and LFP-2 performed well with no signs of cracking. This article presents a discussion on the RDEC fatigue model, pavement thickness design, pavement material characterization test results, pavement instrumentation, accelerated pavement tests under heavy aircraft gear loads, and pavement responses measured using embedded sensors. The test section performance shows that, under loading conditions used in the study, by increasing HMA thickness from 25.4 to 30.5 cm, fatigue cracking was eliminated for the duration of testing (38,000 passes).

Pack: Book and CDInternationally, full-scale accelerated pavement testing, either on test roads or linear/circular test tracks, has proven to be a valuable tool that fills the gap between models and laboratory tests and long-term experiments on in-service pavements. Accelerated pavement testing is used to improve understanding of pavement behavior,

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.
