Description
During the thaw, after a period of frost, we observe the ground below road surfaces is saturated with water, which diminishes their resistance. To preserve those roads that are weakened by the frost, we try limiting vehicle tonnage in circulation on it : what is called a thaw barrier.
Road maintenance support specialist, METEO OMNIUM builds, repairs, and install fluorescein chemical frost depth indicators: the cryopedometer. Road surveillance with a fluorescent cryopedometer allows collecting invaluable data for winter viability.
The principle : collect the road surface temperature and that of the load-bearing ground at different depth track the frost's evolution and anticipate installing thaw barriers.
