Is anyone aware of any standard procedurers or practices that may be available or comonly used for adjusting payment for out of specification aggregates?

We are currently wrapping up a DOT/FAA project in which we had several QA samples of aggregate Subbase and Surface Course with out of spec test results.

The DOT has proposed 2% deduct per % deviation for +#40 sieves and 4% deduct per % deviation for -#40 sieves.

I am just researching for information that may be available or others experience in this situation. I haven't turned up anything so I figured I would give it a shot on Eng Tips.

Thanks
