Vehicle mounted GPR systems collect data in a reasonable time without requiring significant resources or major disruptions to the traveling public. Data collection is assisted with software that provides real-time visual feedback to the field operators about the current coverage and completeness with integrated aerial images, and the path of the vehicle using GPS for each data collection pass across the width of the bridge deck.
Can be performed at highway speeds (45 mph)
No lane closures
Protected vehicle used when traffic conditions are warranted
Periods of data collection are restricted to time when infrastructure and air temperatures above freezing, no standing water on surface of infrastructure, infrastructure surface is dry
