The Challenge
- Honolulu Airport upgrades taxiways with cold planning method
- Three-inch removal of existing asphalt for replacement
- Assesses structural response to aircraft loading
The Honolulu Airport underwent a major construction effort to resurface existing taxiways. As part of that effort, the resurfacing method of cold planning (the controlled removal of the surface layer of existing pavement) was evaluated. This required the removal of existing flexible (asphalt) pavement to a depth of three inches and replacement with a new asphalt wearing course surface layer.
The Hawaii Department of Transportation wanted to evaluate the performance of this method by measuring structural response to airplane loading and various aircraft wheel configurations.
The Solution
Geocomp worked with the Hawaii DOT to develop project-specific instrumentation specifications, which outlined specific type pavement sensors, data collection requirements, and a triggered camera to capture aircraft wheel configurates to correlate with the measured data. The monitoring system implemented by Geocomp included:
- 56 Geocomp Asphalt Strain Gages to measure pavement strains under aircraft wheel loads in existing cold-planed surface and new surface layer
- Two Geocomp temperature trees to measure temperature gradients in existing cold-planed surface and new surface layer
- Stand-alone, solar powered, remotely accessed data acquisition system that can be triggered for data collection based on sensor response or airplane presence
- Triggered, low-light camera system to document type of aircraft and wheel configuration to correlate with measured data.
