Nondestructive Pavement Evaluation of Stewart International Airport’s Runway 9-27

Knowledge of the existing structure and condition is critical to developing a reliable, cost-effective pavement restoration design. Airside pavements present a challenge in this regard, due to the limited time windows afforded for pavement evaluation and the critical nature of ensuring their structural and functional integrity. A nondestructive testing (NDT) survey, incorporating various NDT methods, was utilized to meet this challenge on Runway 9-27 at Stewart International Airport in upstate New York. This runway was programmed to receive improvements, including converting the existing typical cross-slope to a crown section. During low volume hours an integrated testing vehicle equipped with Ground Penetrating Radar (GPR), a high-speed Inertial Profiler, and a high-resolution video camera was deployed to measure pavement thickness and smoothness in addition to capturing video and complemented by a Heavy Weight Deflectometer (HWD) to back-calculate layer moduli along testing lines at various transverse offsets. Analyzed GPR data was compared to ground truth core data provided by the owner (Port Authority of New York and New Jersey) at several locations, and the thickness results were found to correlate fairly well. In addition to producing the asphalt thickness, survey data along each of the test lines was utilized to produce the elevation profile of the top and bottom of the asphalt layer. This information was used by the owner to model the asphalt concrete (AC) layer using AutoCAD Civil 3D. The GPR data yielded an explanation for anomalous cores ranging up to 43 inches thick and avoided the need for more extensive coring. Ultimately, the NDT survey was used to segment the runway along the tested offsets, allowing for a comprehensive and reliable design assessment and construction quantity estimates. Additionally, the data was presented for visualization through a software interface that enables the coordinated simultaneous viewing of video and pavement data.
