Problem 3: A highway embankment is to be constructed along the North Diversion road using soil from a selected borrow pit.DPWH specifications state that soil must be placed in layers and compacted to at least 95% of the maximum density. Also the water should be added to the fill so that the soil is compacted at the optimum moisture content. A laboratory test to determine maximum density and optimum moisture content has been conducted by placing a small sample of this soil into a steel cylinder and compacting it with a drop hammer. The volume of the cylinder is 0.00094 cu.m. The following data has been obtained from this test. Test No. Wet Weight (KN) | Moisture Content (%) 1 14.94 7 2 16.36 11 3 17.93 16 4 18.28 24

Steel rails on a train track are laid with a small gap between them at a temperature of -25 F. The cross-sectional area of each rail is 5 in^2. The steel rails are 40-ft-long. a. When the temperature is increased to 95°F, determine 8. b. Using this gap, what would be the axial force in the rails if the temperature were to rise to 110°F?
A field density test has been conducted in a compacted fill that is currently under construction.The test results indicate a relative compaction of 101-103%, which made the constructionmanager believe the test must be incorrect. He believes it is impossible for the dry unit weightinthe field to be greater than the maximum dry unit weight from the Proctor compaction test.Explain why the relative compaction in the field could indeedbe greater than 100%.
