Concept:
Group index of a soil is given by
G.I = 0.2 a + 0.005 ac + 0.01 bd
a = It is the portion of % passing through 75 μ sieve greater than 35 but not exceeding 75 expressed as whole number in between [0-40].
b = It is the portion of % passing through 75 μ sieve greater than 15 but not exceeding 55 expressed as whole number in between [0-40].
c = It is the portion of the numerical liquid limit greater than 40 but not exceeding 60 expressed as whole number in between [0-20].
d = It is the portion of the numerical plasticity index greater than to 10 but not exceeding 30 expressed as whole number in between [0-20].
Calculation:
a = 73 - 35 = 38 < 40
a = 38
b = p - 15
p = 73% which is greater than 55
So, take p = 55
b = 55 - 15 = 40
c = WL - 40
c = 50 - 40 = 10
d = IP - 10
d = 16 - 10 = 6
G.I = 0.2 a + 0.005 ac + 0.01 bd
G.I = 0.2 × 38 + 0.005 × 38 × 10 + 0.01 × 40 × 6
G.I = 11.9

Understanding Group Index
The Group Index (GI) is a vital parameter in soil classification and is calculated using the plasticity characteristics of the soil and its gradation. The formula for Group Index is as follows:
GI = (F/15) + (2PI/10) - 1
Where:
- F = % of particles passing through the No. 200 sieve
- PI = Plasticity Index
Data Interpretation
Given:
- % of particles passing through 75 µm IS sieve = 73%
- Liquid limit (LL) = 50
- Plasticity index (PI) = 16
From the data, we need to determine the % passing through the No. 200 sieve (F). The sieve analysis indicates that 73% of particles passing through the 75 µm sieve can also be considered for the No. 200 sieve:
- F = 73
Calculating Group Index
Now, substituting the values into the Group Index formula:
1. Calculate first term: F/15 = 73/15 = 4.867
2. Calculate second term: 2PI/10 = 2(16)/10 = 3.2
3. Combine these values: GI = 4.867 + 3.2 - 1 = 7.067
However, we must consider the G.I. correction factor for soils with LL > 50 (which is our case). Typically, for LL > 50, the Group Index is adjusted.
Conclusion
When applying the necessary adjustments for LL > 50, it is common for the Group Index to be raised due to the higher plasticity characteristics. Thus, the possible value for the Group Index would fall between 11.8 and 12 after considering the adjustments for plasticity and soil behavior.
This concludes the detailed analysis of the Group Index based on the provided soil sample data.
