Atterberg Limits: Significance and Factors Affecting it
Significance of the Atterberg Limits: In the upper plastic limit the film of oriented water molecules becomes so thick that cohesion is decreased and the entire soil water mass flows freely under an applied force. The tensions of the water at the lower plastic limit and upper plastic limit are equivalent to pF values and about respectively.

The plastic limit of clays S. K. HAIGH, P. J. VARDANEGA and M. D. BOLTON The plastic limit of soils was rst described by Atterberg in 1911. The threadrolling test was standardised at the US Public Roads Bureau in the 1920s and 1930s, and has subsequently become one of .

3. Test Methods T108 – Liquid limit of road materials This test method determines the Liquid Limit of a soil, this is the moisture content where the material changes from a plastic to a liquid state. This test is identical to with extra amendments generally related to further mixing of the sample.
RESULTS Ocean Drilling Program
Figure F1 shows the results of the Atterberg limits tests plotted on a plasticity chart in order to determine the soil classification based on the Unified Soil Classification System ASTM D2487 (ASTM International, 2004a). From this chart, a cohesive soil has high plasticity if it has a liquid limit >50% and low plasticity if the liquid limit is <50%.

The kaolinites also showed the effect of particle size on the Atterberg limits, but these varia tions are not as great as for the illites. The plastic limit of kaolinite would probably range from less than 25 Lo 40 per cent; the liquid limit from 30 to 75 per centl and the plastic index from 0 to 35 per cent.

ATTERBERG LIMITS TEST INTRODUCTION
ATTERBERG LIMITS TEST INTRODUCTION: The Atterberg limits are a basic measure of the nature of a finegrained soil. Depending on the water content of the soil, it may appear in four states: solid, semisolid, plastic and liquid. In each state the consistency and behavior of a soil is different and thus so are its engineering properties.

Atterberg standards: ASTM D4318 • AASHTO T 89 • AASHTO T 90 • Australian Standard, and ; Index values (Atterberg liquid and plastic limit, plasticity and liquidity index) are automatically calculated from raw moisture content data .
LIQUID LIMIT OF SOIL – WHAT, WHY HOW?
Mar 07, 2015· From test point of view we can define liquid limit as follows. "Liquid limit is defined as the minimum water content at which a pat of soil cut by a groove of standard dimension will flow together for a distance of 12 mm (1/2 inch) under an impact of 25 blows in the device."
Determine The Plastic Limit Of Soil Civil Engineering
This test is done to determine the plastic limit of soil as per IS: 2720 (Part 5) – plastic limit of finegrained soil is the water content of the soil below which it ceases to be plastic. It begins to crumble when rolled into threads of 3mm dia. The apparatus used: i) .
Atterberg limits Wikipedia
The Atterberg limits are a basic measure of the critical water contents of a finegrained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content, a soil may appear in one of four states: solid, semisolid, plastic and liquid. In each state, the consistency and behavior of a soil is different and consequently so are its engineering properties. Thus, the boundary between each state can be defined .

After setting for 6 to 30 hours, the moistureconditioned soil is compacted into a 4in diameter mold. The moisture content is then adjusted, if necessary, to bring the sample to 50% saturation. A 144 psf surcharge is applied and the sample is wetted and monitored for .

Shrinkage Limit Set. Shrinkage limit is the water content where further loss of moisture does not cause a decrease in volume of a specimen. For more indepth information on Plastic Limit, Liquid Limit and Shrinkage Limit, refer to: Atterberg Limits: A Quick Reference Guide.
Devices to measure Atterberg Limits
In 1911, Atterberg introduced the concept of soil consistency depending on water content. Water content corresponding to "conventional" passage between different states is defined as Atterberg Limits which vary from one type of clay to another. Thus a clayish soil may appear in one of four states: Solid, Semisolid, Plastic and Liquid.
