ANSWERS-When the gauge and material has been approved
If a gauge is not approved you have to do what - ANSWERS-Dig to
depth of hole and obtain a sample from the side walls for a speedy test
Determine the dry density by - ANSWERS-Taking the wet density /
1.(moisture) = dry density
To the nearest 0.1pcf
To determine the percent maximum density - ANSWERS-Take the
calculated dry density / the maximum density from proctor x 100 = %
max density to the nearest whole percent

On limerock you use the what reading - ANSWERS-Direct Dial
If a dial reading exceeds 20% then you - ANSWERS-Re-run with half
the sample (10 or 13) and perform the test normally and double the dial
reading by 2
If a dial reads 0 or extremely low - ANSWERS-Re-run with double the
sample (40 or 52) and perform the test and divide the dial reading by 2
