(b) A soil sample from a proposed road construction in Segamat, Johor was sent to a Geotechnical Laboratory UTHM, for a compaction test. The results of compaction test obtained using modified Proctor compaction test is shown in Figure Q4 (b). 3 hi HELP ME! Predict the maximum dry density (Pmax), optimum moisture content (OMC), the dry density at 95% compaction and the range of moisture content at 95% compaction on dry...

Compaction 1. Why do we compact soils to 90 or 95% Standard Proctor (.e. maximum dry unit weight) instead of 100% Standard Proctor? 2. At what saturation is the theoretical minimum void ratio achieved? 3. The following data were determined from a compaction test for a soil with a specific gravity of solids = 2.65 Water content Total Unit Weight (lb/ft) 10 98 106 119 125 128 124 119 (%) Graph the compaction curve (dry unit weight versus water content),...

QUESTION 2 A sand cone test has been performed in a recently compacted fill. The test results obtained are as follows: Initial weight of sand cone + sand = 12.51 lb Final weight of sand cone + sand = 3.26 Weight of sand to fill cone = 1.12 lb Weight of soil from hole + bucket =11.42 lb Weight of bucket =0.21 lb Moisture content test: Mass of empty moisture content can = 18.11g Mass of moist soil + can...

CHAPTER Two 2-3. An undisturbed chunk of soil has a wet weight of 62 lb and a volume of o.s6 ft. When dried out in an oven, the soil weighs S0 Ib. If the specific gravity o solids is found to be 2.64, determine the water con- tent, wet unit weight of soil, dry unit soil. 2-13. The wet unit weight of a soil sample is 18.55...

4. Suppose that a student performed the experiment and calculations perfectly as directed except that, unknown to the student, the balance was not zeroed but weighed 0.100 g too high throughout the experiment. Would the calculated val- ue for the density of the unknown liquid be correct? That is, would it be equal to, higher than, or lower than the true value. Explain your answer in clear and correct English. 16 LABORATORY EXPERIMENTS IN GENERAL CHEMISTRY ed in question 4...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
