Revision of C1040/C1040M-16a Standard Test Methods for In-Place Density of Unhardened and Hardened Concrete, Including Roller Compacted Concrete, By Nuclear Methods

Rationale

The revision is made to clarify that use of the nuclear gauge needs to be in direct transmission during testing and try to eliminate the use of backscatter readings during the testing of RCC for density. This will help to provide uniform testing when determining density measurements in the field.
