The compaction curve obtained for an engineered fill using a standard compaction test . Calculate the bulk unit weight of the fill material in kN/m3 when the degree of compaction is maximum g = 9.81m/s2

2. (a) 2 kg of dry sand is poured into a Eureka can, where it displaces 755 cm³ of water. Calculate the specific gravity of the sand particle. (b) When a 2 kg of the same sand is poured into a measuring cylinder of diameter 6 cm, it occupies a total volume of 1200 cm³. Calculate the void ratio of the sand and its unit weight in this state. (c) The measuring cylinder is carefully filled with water up to the level of the top of the sand, so that the total volume is still 1200 cm³. Calculate the unit weight of the saturated sand in this condition. (d) The side of the measuring cylinder is tapped gently several times, and the level of the sand surface settles to an indicated volume of 1130 cm³. Calculate the void ratio and the unit weight of the saturated sand in its dense state. Take the unit weight of water yw as 10 kN/m³, and the mass density of water as 1000 kg/m³.

Problem 1: For a gravel with D60 0.48mm, D30 0.25mm, and D10 coefficient and the coefficient of gradation. Is it a well-graded or poorly graded soil? - = = = 0.11mm, calculate the uniformity Problem 2: 0.3 mm, D30 The following values for a sand are given: D10 Determine Cu and Cc and state if it is a well-graded or a poorly graded soil. = 0.41 mm, and D60 = = 0.77 mm.

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.
