original excavation free of rock or gravel, debris, vegetable
matter, waste,,and frozen materials.
Backfill excavations as promptly as work permits.
Place backfill materials in layers not more than. 6" in loose

layer to required maximum density. Compaction shall be performed
by the use of approved platform vibratory compactor or other
approved roller equipment. if the desired density is not achieved

spray, hose, jet, or other approved equipment which will uniformly
wet material as it is being vibrated, and so that erosion or
