Not sure if this has come up before but it is kinda neat http://www.youtube.com/watch?v=7TqstDb3ipU Although I can see the air blowing out the hole being potentially dangerous and given safety regs you probably need a 5 person safety crew to set up speed limits and hang onto lollipops every time this thing stops. Ohh yeah that looks like a JD cab?
and it costs how much?
You have to compare the cost of the unit versus the cost of doing it the old school way, particularly that before a road crew can get to work the area has to be set up so they don't get run over by traffic. The claim is that it will do three times as much work with one operator, I think it is best to look at cost per pot hole, how much does it cost to employ three or four people to fix pot holes plus the equipment they need. If it works as advertised I would think that unit would pay for itself in a year as it is essentially doing the work that it would take 9 people to do.
