A. Location: Replace the existing corrugated metal pipe with a new Reinforced Concrete Pipe at the same location

B. Backfilling: Use crushed aggregate as a backfill material.

C. Placement and Compaction: thoroughly hand compact the backfill material under the pipe haunches and then dynamically compact in layers not exceeding 8 inches compacted thickness. Initially compact under the haunches of the pipe by hand tamping or other acceptable means, until reaching a level in which the dynamic tamping can commence. Compact each lift by applying at least eight passes of a hand operated, dynamic mechanical compaction device over the surface of each lift.
