Every soil has optimum moisture content. Higher or lower water content than optimum produces lower density during compaction. The optimum moisture content in relation to density of a soil is normally tested in a soil laboratory using the Standard Proctor Density (SPD) test. 4.4 The best way to compact cohesive soils, such as clay

Maximum Dry Density of Soil and Optimum Moisture Content Test

The determination of maximum dry density and optimum moisture content of the soil is a measure of compaction level of soils. This can be measured by mainly two methods Standard Proctor Compaction Test and Modified Proctor Compaction Test.Both the tests help to determine the optimum moisture content that is required for soil to attain maximum compaction i.e maximum dry density for performing

Unless otherwise directed, water shall not be added to the aggregate on the grade. The aggregate shall be spread in uniform lifts with a spreading and leveling device approved by the Engineer.

When the sub grade is ready, then the base can be dumped on the sub grade, spread, and compacted. Both the sub grade and limestone base should be compacted at optimum moisture. Optimum moisture is the amount ofmoisture that will allow a material to be compacted to maximum density. This number is determined in the laboratory.

Easy Way To Calculate Current Moisture Content And Optimum

The basic premise of this simple method to calculate OMC, optimum moisture content, is based on: · One (1) cubic meter (m3) of soil/sand weighs about 1,800 kg. · 200 grams of soil/sand is 1/9000th of one cubic meter of the soil/sand.
