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.
So basically like this, then?

Sadly, Zamboni not feasible due to climate changes. [Sgt Teacup, Feb 10 2016]

As a truly northern (really north) Canadian, I feel that I am uniquely qualified to drive this zamboni.
For roadwork safety purposes, I have a hunter-orange reflective toque. |

The chase vehicle mentioned could stamp each completed
patch with a certain yellow croissant logo so the citizens
would know who to thank. And send their donations to. [+] |

// heated asphalt dispensers // |
|
| |
Would it be possible to arrange for the machine to spend Sundays dispensing hot asphalt onto those elected representatives responsible for highway maintenance, and follow it up with a good quantity of feathers ? |
|
| |
If the roads were made of ice, you could use a Zamboni
to repair them at halftime. |
|
| |
( Fitting drivers and their cars with skates. AND Fitting pedestrians with skates. AND Fitting buses with skates AND keeping the roads cold could keep the former asphalt workers employed. ) |

[2fries], did you, by any chance, Google "pothole
filling machine"? <link> |
|
| |
Actually, the machine shown in the link is not
particularly elegant, clever or automatic. I could
do better, as could most halfbakers. |
|
| |
Perhaps what is needed is for a publicly-minded
'baker to invent a Ninja Pothole Zamboni
integrated into his or her own vehicle. He or she
could then drive around, parking briefly over
potholes and filling them unobserved before
driving off. |
|

See? Month late, million short, (story of my life). The real question though is why these weren't a thing back in the sixties? |
|
| |
They don't have this already? High time they did. [+] |
|
| |
I can't help but wonder if layers of biodegradable mulch might not make for a dilatant-ish pykrete highway which would self-heal if held suspended within an ice highway. |
|

Flash-freezing isn't going to work. |
|

+ I'd like to drive this, too! |

Good point [2_fries]. Horsetail (Equisetum) is ubiquitous up to the tree line, and way full of silica. Now, we just need a non-lake-poisoning alternative to polyethylene glycol, and--ta da!--ice road oobleck! |

Let's get together over a pint and discuss taking over the northern free worl...I mean, develop our new branch of bioengineering. |
|
| |
(New branch, biology. Heh heh.) |
|
| |
Instead of a pot-hole Zamboni, how about recruiting
members of the living dead to do the job? |
|
| |
These must be operated by guys dressed like flashy, slightly
paunchy, flying trapeze artists, in leotards then, who are
always named The Zamboni's. |
|
| |
Why would flash freezing not work [RayfordSteele]?
|
|
| |
Newton's Law of cooling. The outside would freeze
but the inside would stay quite roasty for awhile,
which would probably buckle the asphalt, and the
comtact zone to the old pavement wouldn't stick
well. |
