With the lowest temperatures in several years I have noticed the potholes and heaving from the frost of the roads is just terrible this year.. Digging holes in roads for my work I can tell you the frost(where its been plowed and not snow insulated)is at least 26 inches deep. It actually goes a bit deeper as things start to thaw.. Ive noticed the centerline of my local expressway has got several crevices and some large potholes that if your passing throws the vehicle around. Not good when the roads are a bit snowy..(Yeah I pass on snowy roads:lol How is the town,state, country going to afford all of this damage??? They put temporary cold patch which is very expensive to tempararily fill the hole then have to decide whether the street warrants a new surface when the weather permits.. There are not too many streets this year that look good after this winter IMO.
