Care should be taken to avoid contact between the pipe and compactionequipment. Compaction of the embedment material should generally bedone in such a way so that the compaction equipment is not used directlyabove the pipe until sufficient backfill has been placed to ensure that the useof compaction equipment will not damage or deflect the pipe.When hydro-hammers are used to achieve compaction, they should not beused within 4 feet of the top of the pipe and then, only if the embedmentmaterial density has been previously compacted to a minimum 85 percentProctor density.4.10.3 Water-JettingThe introduction of water under pressure to the embedment material is notto be used to compact the embedment material.4.10.4 Compaction Equipment SelectionTable 8 illustrates a selection guide for compaction equipment.PropertyMinimum %CompactionEffortRequiredEquipmentTypeMoistureControlSoil Classification (1)Class I Class II Class III Class IVDumped 85% 90% 95%Low Moderate High Very HighHand Knifingin Haunch,Vibratory, ImpactNoneVibratory,ImpactNoneImpactNear optimumto minimizecompaction effortImpactNear optimumto minimizecompaction effortTable 8Notes:1.
