Standard Proctor Compaction Test

Standard Proctor Compaction Test. Proctor compaction mold and hammer a schematic diagram of the proctor compaction mold, which is 4 in. Calculate the percentage retained on 20mm sieve and 4.75mm sieve, and the percentage passing 4.75mm sieve.

How to Test Compaction of Soil? from www.theengineeringcommunity.org

The standard proctor test [4] was used to characterize the compaction conditions of the soil, described by a maximum dry unit weight (γ dmax) of 19.3 kn/m 3 and an optimum water content (w opt) of 9.5% [35]. The modified proctor test was released by the american association of state highways by modifying the standard proctor test. Proctor test the proctor compaction test and its variants are used to determine optimal moisture content for soils.

It is based on compaction of soil fraction passing no. The mould is filled with three layers of soil and each layer is subjected to 25 blows of rammer.

This test is especially useful when determining the relationship between water content and the dry unit weight of soils to establish the maximum density of a soil needed for a fill area. This results in higher maximum soil densities at lower optimum moisture contents.

(1) The Standard Proctor Test, And (2) The Modified Proctor Test.

Equipment for proctor compaction test. Standard proctor compaction test is to establish a relationship between dry density and moisture. For the modified proctor compaction test, the proctor hammer is heavier — 10 pounds instead of 5.5 pounds — and is dropped from a greater height — 18 inches instead of 12.

The Modified Proctor Test Is Identical To The Standard Proctor Test Except It Employs A 4.89 Kg Rammer Falling At A.

The standard proctor test is a soil compaction test which ensures that how its density changes with moisture content and it also reveals the maximum density achievable for that particular soil. In performing this test, the weight of empty mould (without collar and base plate) is first of all taken. We know that the conditions of site and that of the laboratory are different altogether.

In The Standard Proctor Test, The Soil Is Compacted By A 5.5 Lb.

It is then mixed thoroughly with a small amount of water. It is also used to study soil mechanics and other properties like porosity, compressibility, strength, etc. This wet soil is kept covered with a wet cloth for about 5 to 30 minutes.

Proctor (1933) Was The First To Develop A Method Of.

This results in higher maximum soil densities at lower optimum moisture contents. The result will be lower optimum moisture content and higher maximum density for the soil. The standard proctor compaction test measures the maximum unit load for clay.

This Test Is Referred To As The Standard Proctor Compaction Test.

The modified proctor test was released by the american association of state highways by modifying the standard proctor test. It is the most common laboratory soil test and is the basis for all engineered compact soil placements for embankments, pavements, and structural mills.the. Test procedures are similar, but the laboratory compactive effort of the modified method is higher.
