PP 25-1285 PERCENTAGE REFUSAL DENSITY (PRD)
Asphalt Equipment
Percentage Refusal Density (PRD) is defined as the ratio of the initial dried bulk density of the sample to the final density (refusal density) expressed as a percentage. The sample bulk density is determines by weighing in air and water. It is then heated in a split mould and compacted to refusal using a vibrating hammer. The final compacted density is obtained by weighing in air and water.
