Strength and stiffness of compacted crushed concrete aggregate
2013年12月1日 By this factor, even when ρ d increases by compaction at fixed w, due to an increase in S r, the pre-peak stiffness may stop increasing at a certain ρ d value then may start decreasing. With some types of granular material, even the peak strength starts decreasing with an increase in ρ d from a certain value ( Tatsuoka, 2011 ).

Compaction Equipment and Methods: Compaction of Gravel
Compaction itself is basically the action of applying a downward force for consolidation, taking larger and smaller materials and letting them fall and work their way into place. There is a risk of over compaction as you could, especially with larger gravel, break the granules down into smaller pieces and destroying the composition of that gravel.
More‘Self-Compacting’ Soils Underground Construction
Similar to an urban myth, the words ‘self-compacting’ soils have unfortunately taken on an aura of acceptability. Clean gravels and crushed rock are sometimes referred to as “self-compacting,” meaning that if they are dumped in beside a pipe, the material will have a high density.

Choosing the Right Size Crushed Stone for a Solid Foundation: A
Choose the correct size of crushed stone (commonly #57 stone for residential projects) to ensure adequate compaction and drainage. Layering: Spread the crushed stone in uniform layers, each not exceeding 4 inches in depth, to allow for effective compaction. Moisture Content: Ensure the crushed stone has just enough moisture to help in compaction.
