great video, thanks for sharing such a short and helpful information

Compaction is done in layers and Hence, compaction is the Decrease in volume and increase the stability of soil in a dense manner to upstand with the upcoming structure.

Can we drive the roller drum backwards? If yes doest it has any damage to the vibration?

WHERE is the link to your follow-on videos?

[@efrainiscool1]

I came here looking to find a reason why my soil is so darn clumpy.. And came out realizing there are pro's devoting their time to making my gardening IMPOSSIBLE!!! haha jk very well made video keep it up!

Great help! Thank you!

Definition of compaction is really noted

[@Kire1120]

Don't know why I am here but good job nonetheless

[@jasonRhawt]

what happen if you see the contractor pack the soil but your nuclear gauge value is not increasing

[@chickey333]

Good training aid!

[@utpalbiswas6292]

Nice...

[@engineer12v]

Good stuff

Some people fill the foundations with water after digging and leave it for a few days. They claim that now the soil is automatically compacted. Have you studied/experienced it?

[@declanphillips7545]

This is not a common practice and I would exercise caution if considering it as a compaction option. The technique would court failure if the underlying soils are fine grained i.e. silts and clays and therefore should NOT be adopted under any circumstances. The technique has been used to densify coarse grained soils (sands and gravels) as the downward flow of water creates a 'frictional drag' on the soil particles it passes thus 'dragging' them into a denser configuration and reducing the void spaces in the process (See video on water flow in soils kzbin.info/www/bejne/b4KtnKR8mr6Yh6s ). Reaching a specified relative density would be challenging with this technique. In my opinion ... best to stick with tried and tested procedures for densifying soil.

@@declanphillips7545 Thank you sir

[@chickey333]

Throwing a wrench into the works here... compaction does increase the density of soil by removing the air. However, when the soil being placed is saturated and well in excess of it's optimum moisture content, removing the excess moisture in it that wasn't supposed to be in it in the first place would increase the density also. Naturally, in a perfect world, saturated soil that would otherwise be acceptable for use would have it's moisture content reduced or a drier soil material source obtained prior to placement. Heaven forbid an unscrupulous soils contractor would ever dream of veering off from the goal of achieving the highest acceptable placement density possible.... usually.

[@JuggaloBDH]

Optimum moisture content is called OPTIMUM for a reason. Every type of soil has a different optimum moisture content. Going “well above optimum” causes the compaction curve to dip and lowers the ability to reach your required density.

The three is not pronounced tree. wtf.

Sir hindi me batayia please
