Soil lab Liquid and Plastic Limits

Discussion
1. Define liquid limit and plastic limit of the soil,
2. The method describe herein for LL depends on the use of three or more point to find LL.
However, an alternative one-point method can be used based on the following equation:
LL = wN (N/25)0.121
Where wN = water content of the point.
N = number of blows (should be taken between 20 and 30 for good results).
Compare the result obtained by the above equation with the result obtained by the graph.
3. Define the plasticity index, and find it for the tested soil.
4. What are the likely sources of error could be happened in the LL and PL tests.
