Which of the following nearly gives the %gravel of Soil B using AASHTO? which of the following gives the uniformity coefficient of Soil A? which of the following gives the coefficient of gradation of Soil B?
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%.
One of your junior engineers has submitted a construction quality (CQC) plan foryour review before it is sent to the client. The CQC plan includes a compactionspecification for the compacted clay liner. The specification requires that the clay becompacted to a dry unit weight 92% of maximum dry unit weight (standard Proctor)and wet of standard Proctor optimum water content. Compaction and hydraulicconductivity-water content curves for the soil are shown in the figure below. The clayliner is required to have hydraulic conductivity1 x 10-7cm/sec. Find the acceptablezone based on hydraulic conductivity. Does this specification ensure that the requiredhydraulic conductivity will be obtained?

Can I get a step by step for this question? A loose, uncompacted sand fill 6-ft in depth has a relative density of 40%. Laboratory tests indicated that the maximum and minimum void of the ratios of the fill material are 0.9 and 0.46, respectively. The specific gravity of solids of the soil is 2.65. If the final height of the fill after compaction is 5.4 ft, the relative density of the compacted fill is most nearly?

Read the question carefully and give me both a&b right solutions. A proctor compaction test in the laboratory on a borrow pit soil gives maximum unit weight of 19 kN/m3 and optimum water content of 11.5%. The bulk unit weight and water content of the soil in the borrow pit are 17.2 kN/m3 and 8.2%, respectively. A highway fill is to be constructed using this soil. The specifications require the fill to be compacted to 95% Proctor compaction. (a) What is the additional weight of water per unit volume required to bring the moisture content to the optimum value to achieve 95% Proctor compaction? (b) How many truckloads of borrow pit soil will be required for a 100,000 m3 highway embankment - assuming each truck has a capacity of 10 m3 ?
Laboratory compaction test results and fielddetermined in-place density (unit weight) results are reported in terms of dry density or unit weight and not wet density or unit weight. Outline the reasons for this procedure of reporting. (Hint: Consider the soil properties directly related to density or unit weight.)
