S.test#8 : Classification Of Soil

S.Test#8 : Classification of soils AASHTO M 145-91

This recommended practice describes a procedure  for classifying soils into seven groups based on lab determination of particle-size distribution. Liquid limit,plastic limit , and plasticity index evaluation of soils within each group index , should be useful in determining relative  quality of soil material for use in earthwork structure , subbase , subgrade or others .

S.test #5#6#7 Atterberg Limit : Liquid Limit - Plastic Limit - Plasticity Index

Atterberg limit contains 3 tests ( liquid limit , plastic limit , plasticity limit)

S.test #5 Determination of the Liquid limit of soil AASHTO T-89 (Atterberg limit)

This procedure covers the determination of the liquid limit of soil .It covers the change of soil from elasticity position to liquid position .

S.test#6: Plastic Limit AASHTO T - 90 (Atterberg Limit)

The plastic limit of a soil is the lowest water content at which soil remains plastic 

S.test#7 Plasticity index AASHTO T-91 (Atterberg limit)

The plasticity index of a soil is the numerical difference between the liquid limit and the plastic limit.It's the moisture content at which the soil is in a plastic state 

S.test#4 California Bearing Ratio

S.Tests#4: California Bearing Ration AASHTP T 193 - 93 ASTM D1883

This test method covers the determination of the California Bearing Ratio ( CBR) of pavement subgrade , subbase and basecoarse materials  rotary compacted specimen . The test method is primarily intended for - but not limited to - evaluating the strength of the cohesive materials having maximum particle sizes less than 19mm.It is the load to penetrate a cylinder with some speed to 0.1 in. or 01.2 in

S.TEST#3 Density Of Soil using 100lb. Rammer

S.Test#3: Density relation of soil using 100lb. Rammer AASHTO T99

this test method is intended for determining the relationship between the moisture content and density of soils when compacted in given mold of a given size with 10lb rammer dropped from a height of 457mm. Four alternate procedures are provided 

S.test#2: Moisture Content In Soil

S.test#2: Laboratory Determination of moisture content of soil AASHTO T265-91

This procedure is used to determine the total moisture content of a soil . The soil is dried to remove all free moisture . This test measures the weight of the moisture removed from the soil .

S.test#1 : SandCone

S.Test#1: Density and unit weight of soil (SAND CONE) AASHTo 191 - 93

This test method covers the determination of compaction of the field if it's done by sand cone 

Summary of the First Chapter : MATERIAL TESTING

The core of any civil engineering design is the understanding of the behavioural , physical , and mechanical properties of the materials used . 


Today we have finished the " Material testing" category in which we have posted 13 tests , and our NEXT stop is :

" SOIL tests for highway purposes " 

A minor reminder of the tests ,that have been posted, in this photo
