ASTM D 4311/D 4311M:2021

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 nonconformance with the standard. Note 1: Correction factors in Table 1 and Table 2 are for use in place of correction factors provided in Guide D1250 , which do not address requirements for asphalt specifications. 2 1.4 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
