As per the compaction specification, a highway fill has to be compacted to 90% of Indian standard light compaction test dry density. A borrow pit available near the project site has a dry density of 1.78 g/cc at 100% compaction and a void ratio of 0.63. Compute the volume of borrow material needed to construct a highway fill of height 5 m and length 1.5 m with side slope of 1:2. The top width of the fill is 10.5 m. G = 2.7.

GEOTECHNICAL ENGINEERING: The Undisturbed soil at a given borrow pit is found to have the following parameters. The water content is 15%, the void ratio is 0.60 and the specific gravity of the solids is 2.70. The soil from this borrow pit is to be used to construct a rolled fill having a finished volume of 50,000 yd3 . The soil is excavated by means of a shovel and dumped on trucks. When loaded to capacity these trucks are found to contain, on average, a net weight of wet soil equal to 13,000 lbs. In the construction process, the trucks dump their load on the fill, the material is spread and broken up, after which a sprinkler adds water until the water content is equal to 18%. The soil and water are thoroughly mixed by means of dicers (or other similar equipment) and then compacted until the dry unit weight γd=110 lbs/ft3.

4. Specifications require that a fill using borrow soil to be compacted at 95% of its standard proctor maximum dry density. Tests indicate that this maxi-mum is 19.5 kilo Newtons per cubic meter with 12 % moisture. The borrow material has a void ratio of 0.60. Compute the minimum dry and wet unit weight of the compacted soil, compute also the minimum volume of borrow material required to fill 1 cubic meter when compacted.
A subsurface exploration report shows that the average water content of a fine-grained soil in a proposed borrow area is 24.5% and that its average natural dry density is 83.3 pcf. This soil is to be placed in a compacted fill with a dry density specified at 95.5 pcf. -How many cubic yards of borrow will be required to produce 86,000 yd3 of fill? -What is the shrinkage factor for the borrow?
The following are given for a natural soil deposit: Moist unit weight, γ = 17.8 kN/m3 Moisture content, w = 14%; Gs = 2.7 This soil is to be excavated and transported to a construction site for use in a compacted fill.
