The hammer should freely drop from a height of 12" from the surface of the soil, not hammered down by the user as done in the video. Lift the rod up all the way inside of the hammer cylinder which is exactly 12" and then let it drop by itself to the soil.

The modified method is used for Granular Sub Base (GSB layer) and the standard method is used for embankments.
Modified density in the field for GSB is 100% of compaction.
Standard density in the field for SOIL is 98% of compaction.
