ASTM D4311 for Determining Asphalt Volume Correction to a Base Temperature
5. Example of Use
5.1 Example A - Volume of asphalt cement is measured to be 5000 m3 at a temperature of 135°C. Asphalt cement density at 15°C is 1015 kg/m3. Determine the volume of asphalt cement at the standard base temperature of 15 °C.
5.1.1 Column A factors from Table 1 are applicable since density at 15°C exceeds 966 kg/m3 or higher.
5.1.2 A colume correction factor of 0.9266 is read for observed temperature of 135°C. Multiplying the measured volume of 5000 m3 by 0.9266 results in 4633 m3 of asphalt at 15°C.
5.2 example B - Volume of asphalt cement is measured to be 347 m3 at a temperature of 307°F. Asphalt cement density at 60v is 0.960. Determine the volume of asphalt cement at the standard base temperature of 60°F.
5.2.1 Column B factors from Table 2 are applicable since the specific gravity is between 0.850 and 0.966 at 60°F.
5.2.2 A volumn correction factor of 0.9058 is read for an observed temperature of 307°F. Multiplying the measured volume of 347 m3 by 0.9058 results in 314.3 m3 at 60°F.
