: Determine the exact bitumen percentage in recycled materials to ensure they meet modern pavement specifications.

: In most cases, it provides a highly reliable measurement of binder content, though a "correction factor" may be needed for certain aggregate types that also lose mass under high heat.

: The sample is placed in a furnace and heated to high temperatures (typically around 540°C or 1000°F ). : Determine the exact bitumen percentage in recycled

For a quality control engineer or plant manager, this report is fascinating because it solves three big problems instantly: For a quality control engineer or plant manager,

Look for the line. Modern furnaces weigh the sample continuously. The report should show that the scale reading didn't change more than 0.01% in the final 3 minutes. If it kept dropping, the test was stopped too early (unburned carbon left), and the result is artificially high.

Example: If the correction factor is +0.2% (aggregate loses weight), and the furnace measures a mass loss of 5.5%, the corrected asphalt content is 5.5% - 0.2% = 5.3%.
