ASTM D4887/D4887M-11 (R2021)e1 PDF Download

ASTM D4887/D4887M-11 (R2021)e1 is a standard practice that outlines the procedure for preparing viscosity blends of hot recycled asphalt materials for laboratory testing. The practice involves a trial blend process followed by the preparation of batch blends. These batch blends can then be used for extensive evaluation, including tests for viscosity, penetration, ductility, aging properties (such as the Rolling Thin Film Oven or Thin-Film Oven tests), composition analysis, solubility analysis, and other user-selected tests.

The standard assumes that a representative sample of reclaimed asphalt pavement (RAP) is extracted, and the aged binder is recovered using specified test methods, such as Test Methods D2172/D2172M and Test Method D1856. An alternative method using a rotary evaporator is also mentioned, which has been evaluated in the minutes of the 18th Pacific Coast Conference on Asphalt Specifications.

It's important to note that the standard includes informative notes and footnotes that provide additional context and explanations. However, these notes and footnotes (excluding those in tables and figures) are not considered requirements of the standard.
