reporting compaction test results
reporting compaction test results
(OP)
ASTM 2937-04 states NOTE 2—It may be desired to express the in-place density as a percentage of some other density, for example, the laboratory maximum density, determined in accordance with Test Method D 698. This relation can be determined by dividing the in-place density by the maximum density and multiplying by 100.
The question is to what accuracy is the resulting comparison reported to? I have always been taught to round off to the nearest whole number for % compaction. Others argue to report to nearest 10th for % compaction.

Then know in your mind that there is variability: how well things were measured, and the know variation of the gauge (varies based on length of test, surface prep, etc.)
If you repoert exactly what shows on the screen, then you do not add additional variation based on your rounding.
