Weight-Volume relationships

Weight is defined as the quantity of matter contained in a body. Weight can also be defined as the force acting on a body due to gravity. Mathematically, weight can be defined as-

Q2/ For proposed Earth Dam fill, the soil will be compact to (95%) of standard proctor dry density. The test of borrow area indicate that (ydmax = 18 kN/m3) at optimum moisture content (11%). The soil of borrow area at natural condition has (e = 0.65) and (Gs = 2.68). Determine the minimum volume ofborrowrequired to make (600,000 m3 ) of acceptable compacted fill.
Explain about the Field Equipment—Surface Zone Compaction.
Your company has won a contract to provide and compact the fill material for an earth levee (an embankment built to prevent overflow of a river), with the dimensions shown below. The levee fill is a silty clay soil to be compacted to atleast 95.1% of maximum standard Proctor of dry unit weight= 109lb/cu.ft at an OMC of 18.6%. Your borrow pit has a silty clay with an in-situ moist density of 112.6lb/cu.ft at 18.1% water content and a Gs = 2.679. When the soil is excavated and loaded on to your trucks, the void ratio of the material is e = 1.46. Your trucks can haul 401 cu.ft of material per trip. DETERMINE THE FF AND SHOW COMPELETE SOLUTION. ALL FINAL ANSWER WILL BE IN 3 DECIMAL PLACES. 1. Determine the volume of fill required for the levee in cu.ft 2. Determine the volume required from the borrow pit in cu.ft 3. Determine the required number of truck loads.
