Percentage Refusal Density / PRD, is defined as ratio of the initial dried
density of the sample
to the final density (refusal density) expressed a percentage.

It is then heated in a split mould and
compacted to refusal using a vibrating hammer. The final density is obtained by weighing in air and water.
