Abstract:
1. A method of compacting soil containing limestone pinnacles and cavities comprising the steps of: establishing a grid pattern at a worksite, said grid pattern consisting of individual partitions; performing an initial Standard Penetration Test (“SPT”) of said individual partitions; performing a first tamping session consisting of tamping one of said individual partitions with a first tamper plate of a predetermined size and weight, and overlapping each tampered position until the entire grid pattern of individual partitions has been tampered; performing a second tamping session about 96 hours after said first tamping session, said second tamping session consisting of tamping one of said individual partitions with said first tamper plate and overlapping each tampered position until the entire grid pattern has been tampered; performing a third tamping session about 96 hours after said second tamping session, said third tamping session consisting of tamping one of said individual partitions with a second tamper plate of a size less than the size of said first tamper plate and overlapping each tampered position until the entire grid pattern has been tampered; wherein each said tamping session is timed to coincide with pore water pressure causing soil moisture caused through a dilatancy effect to provide soil compaction with minimal noise and vibration.
