The pavement will soften under summer temperatures, leading to rutting, shoving, and flushing (bleeding of excess oil to the surface).

Implementing ASTM D6307 requires an engineered to meet the standard's stringent requirements. These are not standard laboratory ovens; they are specialized pieces of equipment with specific features:

(such as IHS Markit, Techstreet, or ANSI)

It eliminates the need for toxic, ozone-depleting chemical solvents in the laboratory environment.

This factor is subtracted from future test results utilizing that exact aggregate source. Step 3: Loading the Furnace

Statistical limits on acceptable variations between multi-laboratory and single-operator test results.

Precision statements for ASTM D6307 are determined in accordance with ASTM D6300, a practice for developing precision and bias data for test methods. The standard provides both repeatability (within a single lab) and reproducibility (between different labs) limits. It is also important to consider that some types of aggregate may lose a very small amount of mass during the ignition process.

A calibrated ignition furnace, a balance with high precision, and safety equipment are required.

: The asphalt content is calculated as the difference between the initial mass and the final mass of the aggregate, adjusted by the specific correction factor for those materials. AI responses may include mistakes. Learn more

The difference between the actual binder added and the measured loss determines the . 3. Ignition Testing

D6307 Standard Test Method for Asphalt Content of ... - ASTM

The automated system calculates the uncorrected asphalt content percentage (

Aggregates lose a small amount of weight when exposed to extreme heat due to the loss of chemically bound water or minor mineral degradation. Therefore, ASTM D6307 requires a (or correction factor) for each specific aggregate blend.
