Standard Practice for
Volumetric Analysis of Compacted Hot Mix Asphalt
SHRP Designation: P-004
NOTE1.--This practice is based upon chapter VI, Analysis of CompactedPaving Mixtures, of Asphalt
Institute Manual MS-2.1
NOTE2.--This practice is intendedto supplement the volumetric analysis and design procedures contained
in the SUPERPAVE®Mix Design Manualfor New Constructionand Overlays.2
1. SCOPE
1.1 This practice provides procedures to accomplish the volumetric analysis of
compacted hot mix asphalt (HMA) specimens.
1.2 It presents methods for determining:
• the volume percent of air voids (V_, also termed the air voids content);
• the volume percent of voids in the mineral aggregate (VMA);
• the voids filled with asphalt (VFA);
• the effective volume of asphalt binder (Vbe); and
• the effective asphalt content (Poe)
of compacted HMA specimens.
Values of these properties are calculated from the measured specific gravities of the asphalt
binder, the coarse and fine aggregate, and the compacted HMA.
1.3 This practice is applicable to specimens compacted in the laboratory or to
specimens which are cut or cored from field pavements.
