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.

arne 3. Determine the minimum possible voids ratio of uniformly graded a sand of perfectly spherical grains.
A certain saturated sand (S = 100%) has a moisture content of 27.9% and a specific gravity of solids of 2.61. It also has a maximum index void ratio of 0.90 and a minimum index void ratio of 0.33. Compute its relative density and classify its consistency. (Table on the right) Solution: Given the values of mmoisture content, specific gravity and degree of saturation, the void ratio can be estiamted as: e = Thus the relative density is found to be Dr = • According to the table, the soil is classified as %; soil.

The total density of sand in an embankment was found to be 1900kg/m^3 and the field water content was 12% . In the laboratory, the density of the solid was found to be 2660 kg.m^3, and the maximum and minimum voids ratio were 0.63 and 0.44, respectively What is the void ratio of the sand? Calculate the relative density of the sand in the field:
