Infrasense Investigates Airport Pavement Structure using Ground Penetrating Radar (GPR) in San Francisco, California

Share Article

Infrasense recently visited the west coast to carry out a ground penetrating radar (GPR) scan of 12 lane-miles of runway and taxiway pavement, and 240,000 square-feet of apron pavement at San Francisco International Airport in California. The objective of the GPR survey is to provide a detailed pavement structure report with the thicknesses of all asphalt and base layers.

Infrasense’s vehicle mounted, multi-antenna setup

Infrasense recently surveyed multiple runways, a taxiway, and a 240,000 square-foot apron at the San Francisco International Airport. The survey implemented a combination of 400 MHz and 1 GHz antennas mounted off the back of the survey vehicle. The use of both frequencies provided an excellent combination of data resolution and depth of penetration to capture all layers of asphalt and base material. The runways and taxiway data were collected along multiple offsets to provide a comprehensive assessment of the pavement structure along the area of interest.
