The sample is placed inside a specially designed ignition furnace heated to a standard temperature of 538°C (1000°F) .
A solid steel pan placed under the baskets to collect any fine particles that drop through the mesh. Oven: A standard forced-draft oven capable of maintaining for initial sample drying. astm d6307 pdf
The core principle of this standard is the removal of the asphalt binder from the mixture through combustion (ignition) in a specialized furnace. The test measures the mass loss of the sample, which corresponds to the asphalt content. Key aspects defined by the standard include: The sample is placed inside a specially designed
The difference in mass before and after ignition determines the binder content. Key Equipment Required The core principle of this standard is the
It's also important to note that ASTM is currently working on a revision to , a widely used U.S. standard for the same test method. This harmonization effort (Work Item WK97915) is underway to reduce discrepancies between the two standards and streamline industry practices.
): A correction factor must be determined for each specific aggregate blend to account for this mass loss.
