Introduction Using the Particle Size Analysis in the Mechanical Method is a common way to classify soil using sieve analysis. The purpose of this test is to determine the size of grains within a soil sample and classify the soil. It is also a basic introduction to soil mechanics, the types of testing, and analysis needed to classify soils. The sieve analysis method allows grain size distribution to be determined and a Grain Size Distribution (GDS) curve is plotted from the data to classify the soil. This information is useful to engineers and hydrologists; engineers use this information when they build roads or any structures. Theory The basic theory of sieve analysis is that sieves are stacked upon each other with the largest diameter hole on the top and the smallest diameter hole on the bottom; the sieves are then placed on top of a pan to catch the fine-grained soil. Soil can be added to the top layer of the sieve and then the sieves are placed onto a shaker that separates the
