Usually two types of test are performed. The most common laboratory test for soil compaction is the Proctor compaction test.

1 the Standard Proctor Test and 2 the Modified Proctor Test.
. Proctor Soil Compaction Test Procedure. The Nebraska Department of Roads specifies the standard Proctor test ASTM D 698AASHTO T 99 as the method of estimating maximum dry density and optimum moisture content for subgrades and compacted fill sections. The mould is filled with three layers of soil and each layer is subjected to 25 blows of rammer.
The test is named in honor of Ralph Roscoe Proctor de who in 1933 showed that the dry density of a soil for a given compactive effort depends on the amount of water the soil contains during soil compaction. Calculate the percentage retained on 20mm sieve and 475mm sieve and the percentage passing 475mm sieve. The standard Proctor test produces compaction at 12400 ft-lbfft3 while the modified test produces compaction at 56000 ft-lbfft3.
Compaction of soils is a. Proctor 1933 for assessing compacted fill and from then it became a universal standard test. The abbreviation ft-lbf is foot-pounds of force also known as the amount of energy needed to move an object weighing one pound one foot in a linear direction.
1 the standard Proctor test and 2 the modified Proctor test. For fine soil 8-10 of water and for coarse soil 4-5 of water is added. Lab Report Proctor Soil Compaction Test civil engineering department ce206 introduction to soil mechanics laboratory ii proctor compaction test mulhem.
The standard Proctor Test is usually a field soil test. Take about 20kg of air-dried soil. In the Proctor test the soil is first air.
The Proctor compaction test consists of compacting soil samples at a given water content in a standard mould with standard compaction energy. His original test is most commonly referred to as the standard Proctor c. Sieve it through 20mm and 47mm sieve.
The standard Proctor test uses a 4-inch-diameter mould with the compaction of three separate layers of soil using 25 blows by a 55 lb hammer falling 12 inches. The standard proctor compaction test is used in establishing a relationship between moisture content and dry density for the soil under controlled conditions. Weight of the mould without base plate and collar is taken.
B Recommend field compaction equipment that would achieve the desired compaction. If the percentage retained on 475mm sieve is greater than 20 use the large mould of 150mm diameter. The Standard Proctor test and 2.
The collar and base plate were fixed. The standard Proctor compaction test measures the maximum unit load for clay. Approximately 5 kg of soil passing through 475 mm sieve is thoroughly mixed with known water content.
4 a scale moisture cans water a large flat pan for mixing. The standard proctor compaction test was first developed by RR. The height of drop is 305 mm.
Two types of compaction tests are routinely performed. C Specify an appropriate. In the Standard Proctor Test the soil is compacted by a 55-lb hammer falling a distance of 1 foot into a soil-filled mold.
The Proctor compaction test consists of compacting soil samples at a given water content in a standard mould with standard compaction energy. The Modified Proctor tests. This test is referred to as the standard Proctor compaction test and is based on the compaction of the soil fraction passing No 4 US.
It is a standard proctor test for embankment pavements and structural mills. What is the standard Proctor compaction test. Two types of compaction tests are routinely performed.
Proctor 1933 developed a laboratory compaction test procedure to determine the maximum dry unit weight of compaction of soils which can be used for specification of field compaction. In the Standard Proctor Test the soil is compacted by a 26 kg rammer falling at a distance of 310 mm into a soil filled mould. In which proper compaction of soil can be done using the optimum amount of water and controlled compact force.
Each of these tests can be performed by three different methods as outlined in the attached table. The standard Proctor test uses a 4-inch-diameter mould with the compaction of three separate layers of soil using 25 blows by a 55 lb hammer falling 12 inches. The standard Proctor test for a gravelly sand 24 gravel 76 sand to be used as a base course a soil layer above the existing soil of a highway embankment is shown in Figure E55a a Specify the compaction criteria for the field.
The standard Proctor test includes a 095-liter volume cylindrical mold in which the soil mass is placed and compacted in 3 layers. Each of these tests can be performed by using the three different methods outlined in Table 61. The standard Proctor test approximates maximum soil density capable of being produced by early generations of construction equipment.
A compaction mold and a standard 2 kg Proctor hammer were used along with a pre-massed soil sample that passes through sieve no. Procedure for Standard Proctor Test. Up to 24 cash back 3.
The Proctor compaction test is a laboratory method of experimentally determining the optimal moisture content at which a given soil type will become most dense and achieve its maximum dry density. Hammer falling from a distance of one foot onto a mold that is. In the standard Proctor test the soil is compacted by a 55 lb.
Each layer is compressed by dropping 25 times a 25 kg weight falling from an elevation of 30.
