6.  Delete the third and fourth paragraphs and substitute the following:

Construction of roadway aggregate courses, and bedding and backfill
aggregate will be evaluated under Subsections 106.02 and 106.04. Method
2 compaction will be evaluated under Section 106.04. Sample crushed
aggregate for roadway according to Table 308-1. Submit crushed aggregate
for roadway samples to the CO for verification. Materials that do not
meet the approved certification will be considered unacceptable.
