Atterberg Limit Test Procedure. It is the minimum moisture content at which a soil. About press copyright contact us creators advertise developers terms privacy policy & safety how youtube works test new features.

It is advisable to test the liquid limit first. Its shrinkage limit, plastic limit, and liquid limit. It is the minimum moisture content at which a soil.
A Groove Was Cut Through The Pat Of Clay With A Spatula, And The Bowl Was Then Struck Many Times
Assume that the soil was previously passed though a no. ( keep the rod aside and check dia ) Determining the atterberg limits of soils dotd designation:
They Are As Follows, Nearly Sixty Years Ago A Chemist Known As A.atterberg Defined Three Boundary Levels Between These Four States.
In coarse textured soils it is usually difficult to control water content for the liquid limit test and those soils may not even have a plastic. For all the atterberg limits tests, soil samples consist of material passing a no. For determining both plastic and liquid limits, the soil sample must first be sieved through a 0.425 mm sieve (#40 mesh).
In Each State The Consistency And Behavior Of A Soil Is Different And Thus So Are Its Engineering Properties.
Plastic limit test is one of the laboratory tests used internationally to differentiate or classify soils into groups. Depending on the water content of the soil, it may appear in four states: This method should not be used to determine the pl, ll & pi of soils to be used in the design of geotechnical
It Is Advisable To Test The Liquid Limit First.
Determination of shrinkage limit of soil. The liquid limit (ll or w ll), also known as the upper plastic limit, is the water content at which the soil changes from the liquid state to a plastic state. Atterberg defined the plastic limit as, boundary of soil between the plastic and.
As The Starting Procedures Of Liquid Limit Test And Plastic Limit Test Are Common, The Both Tests Are Executed At The Same Time In Most Of The Purposes.
The importance of this atterberg limit test is to classify the soils at different states as every soils has their own liquid limit and plastic limit. Liquid limit test procedure 1. Moisture in test specimens is adjusted by adding water, mixing with a spatula, and allowing to condition for at least 16 hours.
