What should the towel used for blotting the pill be like?

The use of a damp towel for blotting the pill is crucial for ensuring proper moisture levels during the process. A damp towel helps facilitate better adhesion of the asphalt to its surface, which is necessary for accurate and effective testing and calibration in asphalt production. This moisture level allows the towel to adequately absorb any excess material without overwhelming the surface area, as a completely dry towel may not pick up enough material, while a soaked towel could remove too much or disrupt the integrity of the sample. The right amount of dampness ensures that the towel can effectively perform its blotting function without compromising the material being tested.
