Automated Pavement Crack Detection and Sealing System

Sealing cracks in roadways ensures a road’s structural integrity and extends the time between major repaving projects, but conventional manual crack sealing operations expose workers to dangerous traffic and cover a limited amount of roadway each day. To address these challenges, the Transportation research group developed a prototype automated pavement crack detection and sealing system with funding from the Georgia Department of Transportation. The system consists of a stereo camera, light-emitting diodes (LEDs) of two different colors, and an assembly to provide a continuous supply of sealant to longitudinal and transverse sealant distribution systems. In road tests, the system was able to detect cracks smaller than one-eight-inch wide and efficiently fill cracks from a vehicle moving at a speed of three miles per hour.
