Proctor Soil Compaction Test Compaction is the process of densification of soil by reducing air voids. In other projects. Wikimedia Commons. Schematic and dimensions of a compact tension specimen.

When a material is too dry it can not compress very tightly. Again, it is of vital importance to have an experienced lab for this process. The last key step in soil compaction testing involves the use of a soils nuclear gauge.

Back at the job site, a field technician uses a nuclear gauge that has two radioactive isotopes roughly the same mass as the head of a pin , and emits extremely small amounts of radiation into the soil.

Inside of the machine there are sensors that detect how much of the radiation makes it back to the machine. One of the sources is for detecting the hydrogen content, which is a direct correlation with the moisture content.

The other source is for detecting the wet density. Using both of these readings, the nuclear gauge calculates the in-place dry density. This number is compared to the maximum dry density that was determined by the lab testing and is expressed in the form of a percentage. If the material changes even slightly, it could drastically affect the results indicating failure.

An experienced field technician will notice the change and pull another sample for a curve rather than have the contractor keep trying to work the material wasting time and money. To find out more about soil compaction requirements in California click here.

Ground that has not been properly compacted can be detrimental to the structural integrity of buildings, retaining structures, roads and pavements, just to name a few.

Essentially, proper soil integrity could make or break your structure. Since soils are so critical to a structures reliability you will find that soil compaction testing is required most cases. For instance, most regulatory agencies such as, the Department of Transportation and American Society for Testing and Materials all require laboratory testing.

Additionally, you will find that the California and Uniform Building Codes , the geotechnical engineer, and structural engineers will also require soil compaction testing.

There is a very good reason for all the necessity. Basically, if soil tests are not conducted you risk shifting, cracking, and even the collapse of your building. Roadways could also result in disaster by cracking, sagging, potholes, or even sinkholes.

Moreover, having a company that has a seasoned and knowledgeable staff, as well as testing facility, is critical. Not only will a more experienced staff save you time, it will also save you money.

A soil compaction test begins with samples. After excavation a field technician will collect soil samples. An experienced field technician will gather samples from several locations to attain representative samples of various soil types that may be on site.

Each soil type, or mixture thereof, has different properties and can act in different ways. A skilled lab technician will be able to recognize the potential properties of each, and be able to determine best spots for soil extraction.

It can also be valuable to take a sample from the stockpile. This is usually done if the technician notices that the stockpile soil has different properties than the other site soil, or because several soil types are being blended together.

Once at the laboratory the process of determining the optimum moisture content and maximum dry density will occur.

A lab technician will start by sifting and moisture conditioning of the soil. Once the soil is prepped the soil will go into a cylindrical mold to be compacted at various moisture contents and weighted.

Plot the dry density values on the y-axis and the moisture contents on the x-axis. Draw a smooth curve connecting the plotted points.

The values of dry density and corresponding moisture contents for plotting the curve can be computed from the following equation: where,. From Figure 6. Properties and Behavior of Soil - Online Lab Manual Copyright © by MD Sahadat Hossain, Ph.

Skip to content Introduction This laboratory test is performed to determine the relationship between the moisture content and the dry density of soil for a specified compaction energy. Table 6. Practical Application Soil placed as engineering fill embankments, foundation pads, road bases is compacted to a dense state to obtain satisfactory engineering properties such as, shear strength, compressibility, or permeability.

Foundation soils are often compacted to improve their engineering properties. Laboratory compaction tests provide the basis for determining the percent of compaction and water content needed to achieve the required engineering properties, and for controlling construction to assure that the required compaction and water contents are achieved.

Objective The objective of this experiment is: To evaluate the maximum dry unit weight, γ d max and optimum moisture content, w opt , of compaction. Equipment Molds, manual rammer Extruder, Balance Drying oven Mixing pan Trowel 4 Sieve Moisture cans Graduated cylinder Straight edge Standard Reference ASTM D Standard Test Methods for Laboratory Compaction Characteristics of Soil Using Standard Effort Method Put air-dried soil into a large mixing pan 10 lbs.

of soil for a 4-inch mold, and 15 lbs. for a 6-inch mold. Use the balance to determine the weight of the soil samples and compaction molds and bases without the collar , and record the weights. Compute the amount of water to add, using the following methods: Assume the water content for the first test to be 8 percent.

Compute the amount of water to be added by using the following equation: NOTE: The equation for determining the amount of water to add gives the measurement in milliliters, but the soil mass is given in grams. This is not a problem since one gram of water is equal to approximately one milliliter.

Soil compaction refers to combining all the empty spaces and processes within the soil. Soil compaction occurs when soil particles are pressed together, reducing pore space between them.

Compacted soil has a reduced rate of both water infiltration and drainage. Cohesive clay , granular sand , and organic for planting are the three primary soil groups, but only two of these, cohesive and granular, are suitable for compaction.

Back on a construction site, measurements are taken to determine actual values using a number of methods, from the simplistic sand cone test to utilizing a nuclear densometer nuke gauge for testing. The Proctor Compaction Test establishes the maximum unit weight that a particular type of soil can be compacted to using a controlled compactive force at an optimum water content. General Lab. This is usually done if the technician notices that the stockpile soil has different properties than the other site soil, or because several soil types are being blended together. This number is compared to the maximum dry density that was determined by the lab testing and is expressed in the form of a percentage. Unit weights and moisture content field tests could now be expressed as a percent of the laboratory values for the same soil, making it easier for the designer to specify what was required and to document the suitability of the work performed in the field.
