Once testing has begun, is it true that additional dry soil may be added to the moistened soil if too much water is added?

The correct choice is that it is false to say that additional dry soil may be added to the moistened soil if too much water is added once testing has begun. In aggregate base testing, maintaining the integrity of the sample is crucial for obtaining accurate results. If the moisture content has exceeded the desired level, simply adding dry soil does not ensure that the sample conforms to the original specifications or gradation.

Adding dry soil after testing has begun risks altering the sample's properties inconsistently and may lead to misleading results. Proper procedures must be followed to ensure that the moisture levels remain within the specified limits before testing begins. If a sample is deemed too wet, the appropriate course of action would typically involve starting a new sample rather than trying to adjust the existing one post-testing initiation. This ensures that the accuracy and reliability of the testing process are upheld.
