Background
The maximum dry density is a dry density corresponding to a peak point on a relation curve of the dry density and the water content obtained by a compaction test. When the water content is lower at a certain beating number, the dry density after the beating is increased along with the increase of the water content; when the moisture content reaches a certain value, the dry density reaches a maximum value, and at this time, the moisture content continues to increase, but the dry density decreases. This maximum value of the dry density is called the maximum dry density, and the moisture content corresponding to it is called the optimum moisture content.

Firstly, a thin layer of vaseline is smeared on a compacting cylinder, and wax paper or a plastic film is placed on the bottom of the cylinder (a small test cylinder) or a cushion block (a large test cylinder). And pouring the prepared soil sample into the barrel for 3-5 times. When the small cylinder is in a three-layer method, 800-900 g (the amount of the small cylinder is that the compacted sample is equal to or slightly higher than 1/3 of the cylinder height) each time; in the five-layer method, about 400-500 g (the amount of the soil sample is 1/5 which is equal to or slightly higher than the cylinder height) is used each time. For a large test tube, the cushion block is firstly placed on the bottom plate in the tube, and about 1700g of samples are required for each layer according to a three-layer method. Leveling the surface, slightly compacting, compacting the first layer of soil according to a specified compaction number, freely and vertically dropping a compaction hammer when compacting, uniformly distributing the hammer traces on the soil sample surface, after compacting the first layer, galling the sample surface, then loading the sample surface into a sleeve, and repeating the method to compact the rest layers of soil. After the small test cylinder is compacted, the sample is not 5mm higher than the top surface of the cylinder; after the large test cylinder is compacted, the sample should not be 6mm higher than the top surface of the cylinder.
In the process, a large amount of manual participation and steps are required, so that not only is the labor cost increased, but also the possibility of test errors is greatly improved.
