Accurate determination of bulk specific gravity of compacted hot mix asphalt (HMA) samples is an important step in ensuring quality of asphalt pavements. A measurement of the mass and the sample volume are required to calculate the bulk specific gravity. Measuring the sample volu...
Bulk specific gravity of compacted hot mix asphalt using saturated surface-dry specimens. COMPARING LABORATORY DYNAMIC MODULUS VALUES WITH LONG TERM PAVEMENT PERFORMANCE PREDICTIONS As shown in Table 1, the bulk specific gravity of CWC is less than that of CS. Crushed waste concrete in stone mastic...
