Illustration of Pavement Rutting

Rutting in pavement refers to the formation of longitudinal depressions or grooves in the wheel paths of roads. Heavy traffic, particularly from trucks and large vehicles, repeatedly loads and deforms the pavement, primarily causing rutting. Poor-quality materials, inadequate pavement thickness, or insufficient compaction during construction can exacerbate this process. Additionally, high temperatures can soften asphalt, making it more susceptible to deformation under traffic loads.

The presence of ruts on the road surface poses significant safety risks, including water pooling in the depressions, which can increase the risk of hydroplaning and reduce vehicle control. Deep ruts can also cause steering difficulties and lead to vehicle instability, especially for smaller cars and motorcycles. 

Detection and measurement of ruts consists of using methods ranging from manual techniques, like the straightedge and wedge, to advanced automated systems, including laser profilometers, 3D imaging, and sensor-equipped vehicles. High-speed options, like optical systems, allow for efficient assessment at driving speeds. Data analysis software then calculates rut characteristics and visualizes pavement deformation, with the method chosen based on project size, accuracy needs, and resources.

RoadGaugeAI, our web-based software, revolutionizes rutting measurements in an unprecedented way. It measures rutting to mm accuracy using traffic-speed videos from consumer cameras, like a GoPro. Would you like to find out more? Contact us at info@roadgauge.ai or email us on our contact page.
