Index properties of soil


Those properties which helps to access the engineering behavior of soil and which assist in determining its classification accurately are termed as the index properties. index properties include indices which help in determining the engineering behavior such as

1_ strength

2_ load-bearing capacity

3_ swelling and shrinkage

4_ settlement etc.

 

these properties may be relating to

1. individual soil grain

2. aggregate soil mass

The properties of individuals particles can be determined from the  remoulded, disturbed sample.

These depend upon the individuals grains there mineralogical composition size and shape of grain and are independent of soil formation.

The soil aggregates properties depend upon the mode of soil formation, soil history and soil structure. these properties should be determined from the disturbed sample or preferably from in situ test.
