Performance of Open-Graded Drainage Layers (Prince George Airport).
SCOPE:
In cooperation with Public Works and Government Services Canada (PWGSC), the FAA installed sensors on two
sections of asphalt concrete taxiway at Prince George Airport, British
Columbia, Canada. The instrumentation consists of temperature, moisture
content and other environmental sensors. The purpose of this
instrumentation project is to the performance of an experimental
pavement section constructed with open grade (OG) base material, and to
compare the performance of the open grade base section with a control
section constructed to Canadian standards.
The Prince George facility has been
collecting data since installation of the sensors was completed in October
1997. Sensor data and weather data is logged on an hourly basis and
downloaded on a quarterly basis. Data is stored by the FAA at the William
J. Hughes Technical Center.
