**Section 308. - Minor Crushed Aggregate**

**308.06 Acceptance** [Delete the second paragraph and substitute the
following:]{.underline}

Construction of roadway aggregate courses will be evaluated under
Subsections 106.02 and 106.04. Method 2 compaction will be evaluated
under Section 106.04. Sample material from the windrow or roadbed after
processing but prior to compaction at the frequency shown in Table
308-1. Submit samples to the CO for verification. Materials that do not
meet the approved certification will be considered unacceptable.
