Proctor Compaction Test. The most common laboratory test for soil compaction is the Proctor compaction test. The Proctor test was invented in the 1930s by R. R. Proctor, a field engineer for the Bureau of Waterworks and Supply, in Los Angeles, California. The process, which simulates the in-situ compaction

Soil Compaction Test in 4-Steps: Learn With the Ultimate

19/06/2014· Standard Proctor Soil Compaction Test. Standard Proctor Compaction Testing can be performed in a lab. The testing first determines the maximum density achievable for the soil and uses it as a reference for field testing. It also is effective for testing the effects of moisture on the soil’s density. For soil with higher densities, a Modified Proctor Compaction Test which uses higher values

Fundamentals of Soil Compaction

• Standard Compaction Test AS 1289-E1.1 Soil is compacted into a mould in 3-5 equal layers, each layer receiving 25 blows of a hammer of standard weight. The apparatus is shown in Figure 1 below. The energy (compactive effort) supplied in this test is 595 kJ/m3. The important dimensions are Volume of mould Hammer mass Drop of hammer 1000 cm3 2.5 kg 300 mm Because of the benefits from

Proctor Soil Compaction Test Procedures, Tools and Results

22/09/2010· Proctor 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. If the percentage retained on 4.75mm sieve is greater than 20, use the large mould of 150mm diameter. If it is less than 20%, the standard mould of 100mm

6.3.1 Process of compaction Compaction of soil is the process by which the solid soil particles are packed more closely together by mechanical means, thus increasing the dry density (Markwick, 1944). It is achieved through the reduction of the air voids in the soil, with little or no reduction in Licensed copy from CIS: conwl, College Of North West London, 12/01/2014, Uncontrolled Copy. the

Compaction of Soil Test Methods and Effect on

Standard Proctor’s Test for Compaction of Soil. To assess the amount of compaction of soil and water content required in the field, compaction tests are done on the same soil in the laboratory. The test provides a relationship between the water content and the dry density. The water content at which the maximum dry density is attained is obtained from the relationship provided by the tests

How to Test Compaction of Soil? Soil Engineering

The compaction parameters in IS light compaction test are as follows W is the weight of hammer blow = 2.6 kgf, h is the height of fall = 31 cm, n is the number of blows per layer = 25, and I is the number of layers = 3, and V m is the volume of the mold = 1000 cubic centimeter (cc). The total compaction energy imparted on the soil in this test is –

Effects of Soil Compaction extension.psu.edu

Soil compaction increases soil density, reduces porosity (especially macroporosity), and leads to increased penetration resistance and a degradation of soil structure. This degradation is enforced when tillage is used to break up compacted soils. Soil biota suffers from compaction. For example, earthworm numbers and activity will be reduced in compacted soils; water infiltration and

The British Standard Compaction Test for Soils: A Study

25/05/2015· It is recommended that specifications for the compaction test should include a minimum requirement for the effective mass of the sub-base on which the test is performed. The tests also demonstrate the effect of an uneven floor or of a warped base-plate to the compaction mould, either of which allows the mould to rock. Further tests show the errors which may arise if the water is
