The standard Proctor test uses a 4-inch-diameter mould with the compaction of three separate layers of soil using 25 blows by a 5. In the Proctor test, the soil is first air dried and and then separated into 4 to 6 samples.

The soil is then placed and compacted in the Proctor compaction mould in three different layers where each layer receives 25 blows of the standard hamer. Before placing each new layer, the surface of the previous layers is scratched in order to ensure a uniform distribution of the compaction effects.

At the end of the test, after removing and drying of the sample, the dry density and the water content of the sample is determined for each Proctor compaction test. Based on the whole set of results, a curve is plotted for the dry unit weight or density as a function of the water content.

From this curve, the optimum water content to reach the maximum dry density can be obtained. You are here: Home » Testing » Proctor Compaction Test. Proctor Compaction Test in Geotechnical Testing.

It is best practice to verify the OMC with all soils that are going to be chemically treated with a 5-point Proctor made from a soil treated with the stabilizing agent that is to be used as the predetermined dosage. Now that you are confident with your laboratory derived OMC and MDD, several test methods may be used to determine if compaction goals are met in the field.

The first two methods are similar in that a small area is excavated and the void is filled with sand or a pressurized water balloon. The volume of sand or water in the balloon that is necessary to fill the hole can then be determined. Both tests require the unit weight and the water content of excavated soil for calculations.

Nuclear density gauges use controlled, transmitted radiation to measure the density of soil. There are two ways that a nuke gauge can work: direct transmission or backscatter. Direct transmission works by inserting a radioactive probe into the soil via a pilot hole before the transmitted radiation is measured over a short time.

Backscatter is less reliable but faster because the probe is not extended into the soils, so no pilot hole is necessary. Since the nuclear density gauges contain radiation, they are closely monitored and regulated.

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.

Generally, the higher compaction is not necessary for most projects like building pads, parking lots or roads, and the standard Proctor test will yield the optimum results.

Many state DOTs allow what is called a one-point proctor AASHTO T to quickly determine if conditions on the site match those tested in the lab. A one-point uses a family of 5-point Proctor curves previously determined from local soils.

It is useful in that only one test specimen needs to be molded and analyzed, not five. This is faster and less expensive than sending samples back to a lab for analysis but may not be as accurate as a 5-point.

The lack of accuracy is particularly true if the site soils are going to be treated with a stabilizing chemical as the curves would likely not have been developed using the matching stabilizing agent. It is best practice to verify the OMC with all soils that are going to be chemically treated with a 5-point Proctor made from a soil treated with the stabilizing agent that is to be used as the predetermined dosage.

Now that you are confident with your laboratory derived OMC and MDD, several test methods may be used to determine if compaction goals are met in the field.

The first two methods are similar in that a small area is excavated and the void is filled with sand or a pressurized water balloon. The volume of sand or water in the balloon that is necessary to fill the hole can then be determined.

Both tests require the unit weight and the water content of excavated soil for calculations. Nuclear density gauges use controlled, transmitted radiation to measure the density of soil. There are two ways that a nuke gauge can work: direct transmission or backscatter.

Direct transmission works by inserting a radioactive probe into the soil via a pilot hole before the transmitted radiation is measured over a short time. Backscatter is less reliable but faster because the probe is not extended into the soils, so no pilot hole is necessary. Since the nuclear density gauges contain radiation, they are closely monitored and regulated.

What is Soil Testing? Soil testing is an essential part of pre-construction to determine the properties and characteristics of the soil at a construction site. A series of tests are used in conjunction with each other to help engineers and construction professionals Soil treatment stands as a foundational practice in civil construction projects and environmental remediation endeavors.

It involves the adjustment of soil properties to ensure suitability for specific applications. Whether you're a civil engineer tasked with
