Cracking

Cracking is one of the most important defects to catch early in its development in order to maximize the longevity of pavement. Open cracking permits the ingress of water into sub-layers which ultimately accelerates deterioration. This is particularly true in northern climates where water ingress and the freeze-thaw cycle can significantly impact pavement condition in just one season.

In order to effectively manage cracking, it is essential to utilize an inspection methodology that is objective, accurate and repeatable and that can provide the location, extent and severity (width) of cracking. These data are needed for determining the overall condition of pavement as well as for the selection of the appropriate maintenance treatments.

Pavemetrics® Laser Crack Measurement System (LCMS®-2) solves this challenge using objective, 3D+2D based, algorithms that have been developed and proven through the analysis of more than 1,000,000 miles of data from around the world.

Cracking analysis is performed using 3D+2D datasets that have been captured simultaneously via laser triangulation which delivers 100 times the resolution and 10 times the accuracy of typical LiDAR sensors.
