Infrasense Completes Comprehensive Airport Pavement Evaluation Using Ground Penetrating Radar (GPR)

In a groundbreaking study, Infrasense, a frontrunner in subsurface evaluation technologies, has recently completed an extensive pavement structure assessment at a major airport in California. Utilizing state-of-the-art Ground Penetrating Radar (GPR), the evaluation aimed to diagnose the integrity of the pavement layers including Asphalt Concrete (AC), Portland Cement Concrete (PCC), and Cement-Treated Base (CTB).

The GPR Methodology

The GPR assessment employed multi-frequency antennas to effectively gauge thickness and identify underlying conditions of the pavement. The equipment used included a sophisticated configuration of a 1-GHz air-launched antenna, along with dual 400-MHz and 900-MHz ground-coupled antennas, which were instrumental in capturing the expected variations in asphalt thickness.

By mounting each antenna system on a survey vehicle, Infrasense collected integrated GPS data synchronously during the evaluation, ensuring accurate positional reporting. This systematic approach allowed for a detailed mapping of regions showing potential CTB degradation, drawing from the data collected with the 900-MHz antennas.

Analyzing Structural Layers

The GPR analysis meticulously documented the thicknesses and amplitudes at layer interfaces, which were vital for identifying moisture accumulation and possible degradation points found at the PCC/CTB junction. The synergy between the high-resolution data captured by the 1-GHz antenna for shallow layers and the 400-MHz antenna for deeper layers facilitated a comprehensive pavement thickness analysis.

Identified targets were carefully delineated and subsequently converted into Latitude and Longitude coordinates, enabling their integration into mapping software like Google Earth or Geographic Information System (GIS) tools. The findings were systematically presented in a tabular format, offering valuable insights into the pavement conditions with corresponding location-oriented data.
