Mpls-Issues tip: PLEASE trim/cut the previous message that you are responding to. The redundant characters make it harder for Digest readers to read and it needlessly lengthens download times. ----------- I can't speak for why the repairs didn't hold up, unless they were temporary patches that should have been properly repaired. I saw a lot of potholes in San Diego in March this year. Certainly not due to freeze/thaw cycles. As far as technical information, it's probably there in more detail than you would like. I know that there are a few recent books in the Hennepin library system and probably in Minneapolis as well. Do a subject search for either HIGHWAY ENGINEERING or TRAFFIC ENGINEERING. Typically 3-4 inches thick and heavy to boot. Keep to the newer ones. There is also likely to be some stuff on MNDOT's web site talking about experiments in longer lasting pavement. A few year ago, I read an article that contrasted the way highways are built in Germany with the US. Much heavier duty in Germany.
