My theory is that in the old days hot tar was used to repair potholes, where as today they use cold stuff.
by using hot, any water in the pothole would boil off, as well as the tarmac setting harder.
today, any water stays sat under the repair, just waiting to freeze, popping out the repair like a champagne cork out of the bottle.
I know 'repairs' around here, that have lasted less than 2 days....
