A pavement engineer is in the process of developing the necessary data for the soil optimum moisture content on a highway project. However, the lab is running behind the schedule, and it has reported only one moisture-density data point (at 10% moisture content, dry density is 126 lbs/cft). The contractor is under pressure to start the soil compaction and needs to know the “optimum moisture content”. With only one data point provided to you, how would you go about offering a sound “engineering estimate” on the optimum moisture content?
You MUST report your rationale, and fully document your references. Attach any charts, tables, etc. to your homework assignment (submit all as one file).
