    Compaction testing report

    Ron, the deficiency of the report is that it doesn't show the actual field density and this is against ASTM, the reporting uses that correction option in D4718 wrongfully. Thank you for the discussion. DBasement, you do not correct the field densities, you write them down and report them, ASTM...

    Compaction testing report

    Ron, ASTM 4718 at 4.2 provides two equations to correct field moisture content and field density to compare them with uncorrected Proctor density and optimum moisture content. The report is from a real life, there are hundreds of the same reports and all of them signed by a professional engineer.

    Compaction testing report

    I'm sorry for the misunderstanding. The actual density of material measured in the field was above 2300 kg/m3, then it was corrected down, according to the second option in the ASTM standard, and compared to uncorrected MPMDD. The question is - is it allowed to submit a compaction testing report...

    Compaction testing report

    This is the whole report. Correcting 2270 kg/m3 for 38% OS will make it over 2400 kg/m3. Field densities are in the 2150-2200 kg/m3 range and still make 95% or higher relative compaction.

    Compaction testing report

    Here is the link to the report filehttp://files.engineering.com/getfile.aspx?folder=021a1489-7cee-4d12-9850-b4d97d87f9c9&file=Report.png

    Compaction testing report

    The attached report shows results of compaction testing on 75 mm minus crushed rock material with 38% oversize. The Modified Proctor value is 2270 kg/m3 at 7.7% MC. The required compaction was 95%. Could anyone tell me if this report is legitimate based on ASTM standards.
