Aug 07, 2020· This can be also explained by concept of soil structure and electrical double layer theory. Fig.15.1. Compaction curves for clay. Compactive effort: As the compactive effort increases maximum dry unit weight increases in a decreasing rate. However, the OMC value decreases as the compactive effort increases.

Mar 01, 2020· 10. Following Rule 8, open-graded aggregates generally will require more energy (larger compactors) to achieve optimal compaction compared to dense-graded aggregates. 11. The "as-placed" compaction of open-graded aggregates varies depending many factors including drop height, volume of material, moisture content and particle …

The loose drop weight of a relatively uniform (all the rocks are similar size and shape) 3/4 stone will be about 80-90% depending on the stone (angularity and phi). Presuming that you are compacting to of some form of proctor density, because you're awesome at compacting and have a monster machine (and thin lifts), that's 100/80=125%

With the addition of marble waste aggregate (MWA), the compaction factor decreases as the ratio rises. This can be attributed to the smooth surface and less absorption of MWA than normally used coarse aggregate. While the inclusion of stone dust (SD), the compaction factor increases as the percentage of SD increases.

Nov 11, 2019· Crushed stone: The term "crushed stone" usually refers to stone that has a mixture of stone dust in it. This type of stone is best used for a base when heavy compaction is needed. As a result, it is typically used for the base of concrete and paving projects, foundations of structures, and driveway bases.
