You need to check the field compaction of a layer of soil. The compaction specifications are written as "compact dry density to be at least 95% of the maximum value by the modified Procter laboratory test" and "wet side of the optimum water content." A. From the field sand cone test, you got the wet mass of excavated soil as 4200g, and the dry mass as 3800g. The weight of the standard sand filled in the excavated hole is 2800g, and the density of the sand is known as 1.4 Mg/m³. B. The laboratory compaction test (modified Proctor test) result is shown below. Table. Results of modified Proctor test Test # Pa (Mg/m³ w (%) 1 1.84 5.7 2 1.89 7.1 3 1.96 8.9 4 1.99 10.1 5 1.99 11.1 6 1.93 12.7 7 1.87 14.1 Answer following: i. What is the filed compacted dry density? ii. iii. What is the field water content? What is the relative compaction? Does the test meet specifications? iv.
