EXPERIMENT 9 MOISTURE-DENSITY RELATION …

Engineering Properties of Soils Based on Laboratory Testing Prof. Krishna Reddy, UIC 91 EXPERIMENT 9 MOISTURE-DENSITY RELATION (COMPACTION) TEST Purpose: This laboratory test is performed to determine the relationship between the moisture content and the dry density of a soil for a specified compactive effort. The compactive effort is the amount of mechanical energy that is applied to the soil mass. Several different methods are used to compact soil in the field, and some examples include tamping, kneading, vibration, and static load compaction. This laboratory will employ the tamping or impact compaction method using the type of equipment and methodology developed by R. R. Proctor in 1933, therefore, the test is also known as the Proctor test.

Oct 10, 2002 · Enough water should be added so that the mixture may flow freely (see Photo B). (5) Using a scoop, pour the prepared soil into the lower chamber using a circular motion to fill it to a depth of 1.5 cm. A uniform layer should be formed. (6) Use the tamping device to compact the layer of soil. Use

Aug 30, 2002 · The direct shear test is one of the oldest strength tests for soils. In this laboratory, a direct shear device will be used to determine the shear strength of a cohesionless soil (i.e. angle of internal friction (f)). From the plot of the shear stress versus the horizontal displacement, the maximum shear stress is obtained for a
