About 15g of dried soil passing through IS 425 micron is taken for plastic limit determination and is mixed with a sufficient amount of water which would enable to soil mass become plastic enough to be easily shape into a ball. When a diameter of 3 mm is reached, the soil is remolded into a ball.

The process of making the threat and remolded continuous till the threat at a dia. Of 3 mm, just start crumbling.

As soon as water added to soil sample and thorough mixing the powdered form of soil mixes with water and forms a tight mass and remains as a plastic form. The limit of changing of plastic mass is known as plastic limit. It's completely known through practical doing instead of reading through books.

Liquid limit - soil contain water with small shear strength.

Plastic limit -soil contain water in which the soil crumble into 3mm diameter.

Shrinkage limit-soil contains water 100%. It is fully saturated soil. From shrinkage limit the water content decrease.

Plastic limit [Wp].

The minimum water content at which the soil can be rolled into a thread of 3mm in diameter without crumbling. It's called THREAD TEST.

Plastic limit (Wp) is defined as the minimum water content at which soil begins to crumble when rolled into a thread of 3mm dia.

The plastic limit is correct because when we perform this test we take the moisture content where the sample is crumbled at 3mm.

It is the limit at which soil stops behaving as a plastic material. It can be determined by plastic limit test or thread test.

It's plastic limit, the water content at which the soil begins to crumble when we form 3mm thread.

At the beginning of crumbling it's plastic limit but after that it's shrinkage limit.
