ASTM D2872-19 PDF Download

ASTM D2872-19 is a standard test method that measures the effect of heat and air on a moving film of semi-solid asphaltic materials. It is used to determine the approximate change in properties of asphalt during hot-mixing at a temperature of about 302 °F (150 °C), which is typically used in pavement construction. The test method involves measuring viscosity and other rheological properties of the asphalt before and after the test, and calculating the mass change, which indicates the volatility of the asphalt.

It is important to note that the quality of the results obtained from this test method depends on the competence of the personnel performing the procedure and the calibration and maintenance of the equipment used. Compliance with Specification D3666 is recommended to ensure reliable results, although it does not guarantee complete accuracy. The standard also includes references to explanatory notes and footnotes that provide additional information, but these should not be considered as requirements of the standard.
