Pot-hole Zamboni

For whatever reason the pot-holes opening up around our city have been far more numerous than at any other time in the sixteen or so years I've lived here.
Frost heaves mostly.
The repair of these calls for shutting down entire lanes of traffic and paying night-shift wages to repair pavement at non-peak hours with much man power.

I propose a single trailer which could be towed at low speed behind any municipal vehicle equipped to haul a load which would have the following attachments arrayed from front to rear:

-Powerful jets of compressed air vented through forward curving lateral slits to blast debris/ice/snow/puddles/ what-have-you to the sides of the lane which will be collected by sweeper attachments at the rear sides of the trailer.
-Several rows of propane torches to dehumidify and prepare each hole for filling.
-Three stages of heated asphalt dispensers interspersed with cooled vibrating rollers.
-An excess asphalt collection conveyor.
-A liquid oxygen or nitrogen cooling unit to blast chill each hole
-A road waste collection sweeper mentioned above, (could be a secondary chase vehicle allowing extra cooling time before traffic commencement).

No stoppage of traffic.
No overtime or nightshift pay.
...and no front-wheel alignment bills which the city feels no responsibility to cover.

Win win win.
