COPILULILL. 4.29 A liquid limit test has been performed on a soil using the Casagrande cup. In this test, exactly 25 drops of the cup were required to close the bottom of the standard groove along a longitudinal distance of 1/2 in. A moisture content test was then performed on the tested soil and yielded the following results: Mass of soil + can before placing in oven 52.20 g Mass of soil + can after removal from oven 41.52 g...
