A sand cone test was conducted for quality control during the compaction of sandy clay. The data are as ollows. Calibration to find dry unit weight of the standard sand Mass of Proctor mold 4178 grams Mass of Proctor mold and sand 5609 grams Volume of mold 0.00095 m Calibration of sand cone Mass of sand cone apparatus and jar filled with sand 5466 grams Mass of sand cone apparatus with remaining sand in jar 3755 grams Sand cone test results Mass of sand cone apparatus and jar filled with sand 7387 grams Mass of excavated soil 2206 grams Mass of sand cone apparatus with remaina sand in jar 3919 grams Water content of excavated soil 9.2% (a) Determine the dry unit weight. (b) The standard Proctor maximum dry unit weight of the sandy clay is 178 kNim' at an optimum wa- ter content of 10%. The specification reoquires 95% Proctor dry unit weight at acceptable water contents ranging from 9% to 10.8%. Is the specification met? Justify your answer.

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
