How much does density matter? - Asphalt magazine

The normal target in-place density on a “dense” hot-mix asphalt pavement is 92 to 93 percent of Gmm (or 7 to 8 percent air voids). If a pavement has low density (usually defined as less than 92 percent of Gmm), the air voids are interconnected and premature pavement distresses can result. These may be in the form of premature oxidation ...

ABSTRACT This work aims to determine the compactness/density of hot mix asphalt by measuring its permittivity by means of step‐frequency radar. As hot mix asphalt (HMA) is mainly made of rocks; their dielectric properties are measured in the frequency range of 0.5 ‐ 4 Ghz with step‐frequency radar, using cylindrical cavities. The results show that the rocks can be
