"Now things have changed. There is a futuristic new machine called the pothole killer that allows one person–who never has to get out of the truck cab–to 'hot patch' 100 potholes in a day. (Watch the video for details.) In other words, the machine makes human labor nearly 100 times more efficient in repairing damaged roads. Fixing a pothole the old way: $70; Fixing a pothole the new way: $3. Technology at work, children.
The company that makes the device, Patch Management, also claims that repairs made by the Pothole Killer last four times longer than those done by old-fashioned "throw and go" technique (i.e. what road crews generally do)."
