Significance and Use
Asphalts change in volume with change in temperature. They are loaded or transferred at widely varying temperatures. Volume correction factors are used to adjust bulk volumes measured at those temperatures to corresponding volumes at a base temperature of 15°C or [60°F] for the purposes of custody transfer and accounting operations.
Correction factors as provided in this practice have proven to be sufficiently accurate for the intended purposes.
Coefficients of expansion used for development of data in this practice are as follows:
1.1 This practice provides tables of volume correction factors which may be used to convert volumes of asphalt measured at different temperatures to a volume at a standard base temperature. These tables are applicable to all types of asphalts except emulsified asphalts.
1.2 This practice provides tables to convert asphalt volumes to 15°C [60°F] from volumes measured at any temperature from −25 to +275°C [0 to 500°F].
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
