A friend of mine who is retired from the Michigan Department of Transportation was watching them put down the crack fill and couldn't believe the way they were doing it.
He said when they made the repair they squeegeed the access tar off after filling crack area. I have seen and run over some that the tar was about 1 inch higher than the road way.
It does give you the pucker factor. Now when riding alone I try to run over some of them, just to try to get used to the feeling.
