Siberian georadar to look for road defects in real time
15 Mar '17
Scientists at the Tomsk State University (TSU) in Siberia are working on software for real-time analysis of data obtained with a georadar during road scanning, TSU announced. The software is expected to be able to generate 3D images of roadbed layers for composition analysis and identification of construction flaws and/or defects caused by vehicles or weather conditions.
“Today, to check the roadbed specialists have to break it to take a piece and then analyze in a lab. Our georadar is fixed on a vehicle and can scan the roadbed with radio waves in real time as the vehicle is moving, leaving the road intact. The radar can “see” a line of the road two meters wide,” said Ilya Tseplyaev, a TSU postgraduate and the developer of the project.
Data collected by the radar is then processed with the help of proprietary software Mr. Tseplyaev has developed. Based on fast radio image development algorithms, the software is said to be able to generate 3D images of every crack, air inclusion or alien object, and other defects roads typically have. Monitoring the situation will help authorities better supervise the construction of new roadbeds and repairs of old ones.
The system is GPS compatible and will show the exact location of a flaw on a road for repair crews to be able to swiftly arrive and address the problem, and also create a map of dangerous spots on the road.
The GRT-XX georadar was designed by Radiovidenie, a TSU spinoff start-up, in collaboration with Moscow’s Gelion Group.
