  • Compaction - Pavement Interactive

    Compaction Measurement and ReportingFactors Affecting CompactionCompaction EquipmentCompaction SequenceCompaction reduces the volume of air in HMA. Therefore, the characteristic of concern is the volume of air within the compacted pavement, which is typically quantified as a percentage of air voids in relation to total volume and expressed as “percent air voids”. Percent air voids is calculated by comparing a test specimen’s density with the density it would theoretically have if all the air voids were removed, known as “theoretical maximum density” (TMD) or “Rice density” after the test procedure inventor. Although percent air voids is the HMA characteristic of interest, measurements are usually reported as a measured density in relation to a reference density. This is done by reporting density as: 1. Percentage of TMD (or “percent Rice”). This expression of density is easy to convert to air voids because any volume that is not asphalt binderor aggregate is assumed to be air. For example, a density reported as 93 percent Rice means that there are 7 percent air voids (100% – 93% = 7%...
