Abstract

A series of full-scale accelerated tests to validate and improve current airfield pavement design and rehabilitation has been conducted at the National Airport Pavement Test Facility (NAPTF), which is operated by the Federal Aviation Administration (FAA). Construction Cycle 4 (CC4) consisted of unbonded concrete overlays and included two phases: the Baseline Experiment and the SCI Validation Study. The experiment included three structural cross-sections subjected to triple dual-tandem and twin dual-tandem loadings. Distress surveys and nondestructive testing were conducted regularly on the test items. Various instruments were installed at designed locations within the test items to capture mechanical behavior of the unbonded concrete overlays and underlying slabs. Linear position transducers (LPT) are one type of installed instrument, which were used to measure the vertical movements of both underlying and overlay pavement slabs due to environmental factors and moving loads.
