Wow!

It has been an intense two weeks around here.

You may remember from one of my old posts that I had been tasked with determining the cause of a road failure in a 7 year old subdivision. Let me just say that all the assumptions I had when I started this quest and when I wrote that post turned out to be wrong.

Each day I would come to work convinced I knew what the problem was…only to be left scratching my head at the end of the day. It was a real puzzle.

On the surface, it appeared everything had been done by the book. After digging into the files and investigating in the field, something finally came up.

It turns out that the contractor was not experienced in preparing soil cement base. Geotechnical corings taken of the base and pavement show little to no base in some areas and weak base in other areas. The roads have failed because of the base failing and the base failed because the contractor did not prepare it properly.

Our inspector found soft spots and insufficient base all through the subdivision…However…his supervisor overruled him and allowed the base to pass inspection. That is what prompted my last post on a similar topic found here.

Anyway. Check out my report. I am proud of it and if you have a hard time falling asleep at night, this report should knock you right out.

It’s in pdf format, so have fun. You know you want to read it…don’t you?
