Earthwork: Q-A

1 In soil compaction test, if a test result exceeds 100%, should engineers accept the result?
2 What are the different applications of draglines, backhoes and shovels?
3 For compaction of free-draining sands or gravels, what is the optimum moisture content to achieve maximum density?
4 Is it worthwhile to carry out tests on particle density of soil particles for geotechnical design?
5 In determining the effective stress parameters of a soil sample, which test is preferable, consolidated undrained test or consolidated drained test?
