Spontaneous Potholes
Seeing as we appear to be collectively omniscient (dat means we know everyting coz we is clever) can someone please explain to me how this could have
appeared outside my garage this morning, because it wasn't there two days ago...
I'd noticed before that potholes do seem to just suddenly materialise on busy roads, and i'd assumed that it went something along the
lines of once the surface is broken it's very much weaker than before and traffic over it will rapidly expand a small crack into a big hole. But
this is outside my garage, behind a block of houses. I can count how many times a car will go over that spot in a day without taking my socks off, so
how has it appeared and grown in such a short space of time? 
EDIT: It was about a foot across when I took the picture, I wouldn't be suprised to find it's grown to a couple of metres by tomorrow, in
a week it'll either be covering all of Surrey or so deep Tibetans will be popping up out of it to say Hi...

Water under the top then frost. The frost makes it break out suddenly.

Hmmm its happening around these parts with alarming regularity Martyn.
I would hazzard a guess, that at some point, oil or indeed fuel has seeped into the tarmac at that point, and therefore degraded the area of said
spillage......

*cough* wasn't me *cough*
OK, so I can undertand that a frost cycle could have cracked it, or some form of chemical degradation may have weakened it, but i'd expect to
see a couple of biggish slabs break from the surface first, not the nearly-gravel it's turned into already

Yup Martyn, oil/fuel/chemicals (some) do just that! Can disintergrate tarmac to dust!......almost

Spontaneous potholes are more of an accepted way of life than an anomaly here in Michigan. We have two seasons here, winter, and road construction. I
always knew the two were somehow related.
