A group of students from Agawam High School in Massachusetts have invented RoadIron, a pothole detection and prevention device.

RoadIron uses ground penetrating radar to detect potential potholes below the road surface, then it drills a small hole and fills the cavity with a polymer. If you want all the details, the full report (PDF) is available for your perusal.
