Bulk density of bitumen

WebAnd the density of the bitumen is calculated as 1.025g/cm. 3. Combining the Equation 1 and 2, the measured bulk density, in situ porosity, mineral density, and bitumen density, the true porosity is calculated as 15.5% for #1, and 18.2% for sample #2; and the bitumen saturation is 52.4% for #1, and 43.8% for #2. WebCompaction reduces the volume of air in HMA.Therefore, the characteristic of concern is the volume of air within the compacted pavement. This volume is typically quantified as a percentage of air voids by volume and expressed as “percent air voids”. Percent air voids is calculated by comparing a test specimen’s bulk density with its theoretical maximum …
