Weights required for the bulk sample will .Proctor Compaction Test. Test Equipment. Test Procedure. Calculations. Gallery. Media. Introduction. Compaction of soils is a procedure in which a soil sustains mechanical stress and is densified. Soil consists of solid particles and voids filled with water or/and air.The Proctor compaction test, also known as the Proctor density test, is a laboratory experiment standardized by the American Society for Testing and Materials (ASTM). It determines the optimal moisture content and maximum dry density that can be achieved .the standard laboratory compaction test which is developed is commonly called the Standard Proctor Test. According to Proctor, the compaction of a soil mass is dependent on the following four major factors: 1. Soil .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. The test is named in honor of Ralph Roscoe .proctor compaction test procedureProcedure of the Standard Proctor Test. Equipment Required. Before performing the Standard Proctor Test, gather the following equipment: Standard Proctor compaction mold with a detachable base and collar. Standard Proctor rammer with a mass of 2.5 kg .This is where Proctor testing comes in. The Proctor compaction test, also known as the Proctor density test, is a laboratory experiment standardized by the American Society for Testing and Materials (ASTM). It determines the optimal moisture content and maximum dry density that can be achieved for a given soil with a certain compaction effort.

Each layer is given 25 blows of the compaction hammer or rammer if the mold diameter is 4 inches and 56 blows if the mold diameter is 6 inches. The drop height of the hammer is 300mm or 12 inches. The .
The Proctor compaction test (or heavy compaction test) is a laboratory test which is used for experimentally determining the optimal moisture content (O.M.C.) of soil at which the given type of soil specimen will become most dense and achieve its maximum dry density (by removal of air voids). This test is named in the honor of Ralph .
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. This test is referred to as the Standard Proctor Compaction Test. It is based on compaction of soil fraction passing No. 4 U.S. sieve.
Procedure of the Standard Proctor Test. Equipment Required. Before performing the Standard Proctor Test, gather the following equipment: Standard Proctor compaction mold with a detachable base and collar; Standard Proctor rammer with a mass of 2.5 kg and a free fall height of 30.5 cm; Soil sample; Balance with a sensitivity of 0.01 gTwo types of compaction tests are routinely performed: (1) the standard Proctor test, and (2) the modified Proctor test. Each of these tests can be performed by using the three different methods, outlined in Table 6.1. In the standard Proctor test, the soil is compacted by a 5.5 lb. hammer falling from a distance of one foot onto a mold that is .Proctor Soil Compaction Test – Procedures, Tools and ResultsThis can be measured by mainly two methods Standard Proctor Compaction Test and Modified Proctor Compaction Test. . The procedure for carrying out the standard Proctor test are as follows. Collect the soil sample weighing 3kg. The sample must be 3kg after air drying it. Usually, this soil will be pulverized soil that passes through 4.75mm sieve. 5.3.1.1 One method to design and control the compaction of such soils is to use a test fill to determine the required degree of compaction and the method to obtain that compaction, followed by use of a method specification to control the compaction. Components of a method specification typically contain the type and size of compaction .
Fig. 1: Proctor Mould & Metal Rammer Metal mould (volume = 1000 cm3 for 100 mm . water content - dry density relation using heavy compaction”. 4. Procedure 1. Take a representative portion of air-dried soil large enough to provide about 5 kg of . IS sieve is used for the test. Soil is compacted in five layers, each layer being given 55PROCEDURE – Proctor Compaction Test. 1. About 2.5 kg of loose soil passing through 4.75 mm sieve is taken. 2. The empty proctor mould is weighed in the platform balance. 3. The proctor mould is filled with the .
The Modified Proctor Test is of great importance and is widely used in the construction of roads, highways, earth fill dams, earth filling, Airports, etc. In modified Proctor test, the soil is compacted in the given mold in Five .
Two types of compaction tests are routinely performed: (1) The Standard Proctor Test, and (2) The Modified Proctor Test. Each of these tests can be performed in three different methods as outlined in the attached Table 1. In the Standard Proctor Test, the soil is compacted by a 5.5 lb hammer falling a distance of one foot into a soil filled mold.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. . PROCEDURE: 1. Take a representative oven-dried sample, approximately 5 kg in the given pan. Thoroughly mix the sample with sufficient water to . Standard proctor test or proctor compaction test was the original test devised by an American engineer Ralph R. Proctor showing that for a given compaction effort, the density of soil depends on the type of soil and moisture content. We know that the conditions of site and that of the laboratory are different altogether. Standard Proctor Test was developed by R.R. Proctor. This test is used to determine the optimum moisture content for the soil under given compaction. 1. Apparatus Required a. Standard Proctor Apparatus i. Cylindrical metal mold of an internal diameter of 4 inches ( 102 mm ) and effective height of 4.6 [.]
A Proctor Compaction Test is an important test that can help to determine the maximum unit weight to which a specific type of soil can be compacted using controlled compactive force at the optimal water content. . Proctor Compaction Test Procedure. First, it is necessary to obtain around 3 kilograms of soil and pass it through the #4 sieve. .proctor compaction test procedure Proctor Soil Compaction Test – Procedures, Tools and ResultsProctor Soil Compaction Test Procedure. Take about 20kg of air-dried soil. Sieve it through 20mm and 4.7mm sieve. Calculate the percentage retained on 20mm sieve and 4.75mm sieve, and the percentage passing 4.75mm sieve.
