Moisture susceptibility is a primary cause of distress in HMA pavements. HMA should not degrade substantially from moisture penetration into the mix. HMA mixtures may be considered susceptible to moisture if the internal asphalt binder-to-aggregate bond weakens in the presence of water. This weakening, if severe enough, can result in …

X3.1 Scope—This is a titrimetric test method for determin- ing phosphorus in samples of limestone, quicklime, or lime hydrate. A fairly large sample weight is required because this test method is not sensitive enough for an accurate analysis at the low levels of phosphorus frequently encountered in lime- stone rock.

The moisture content of the food can be measured with a moisture metre. Alternatively a small sample of the dried food is ground into small pieces, weighed and placed in an oven at 100°C for 4 hours. It is reweighed and the moisture content calculated. Moisture content (%) = initial weight - final weight * 100

The same compactive force is used for each point, while the moisture content is changed. As you can see, the change in moisture content results in a change in dry density that follows the theoretical explanation provided above. Simply put, adding water to a dry soil during compaction allows soil particles to slide past one another more easily.
