Kita menjalankan lab. soil compaction. We plot the dry density vs moisture content graph. From there we determine the optimum moisture content that gives the highest dry density value.
Katakan after doing the lab. test, the optimum moisture content is 5%.
1) Bagaimana kita nak control 5% optimum moisture content di tapak, so as to get the max dry density?
2) Jika hujan lebat, what happen to the compaction of the soil, knowing that too much water, according to the dry density vs moisture content graph, the dry density value will drop.
