Asphalt Binder Analyzer (Ignition Method)
The ignition test is the most common method for determining the Asphalt Binder Content of Hot-Mix Asphalt (HMA) and gradation. The ignition method, allows for the asphalt binder in an HMA sample to be burned off in an oven at temperatures above the flame point of the binder. Asphalt binder content is then calculated by subtracting the mass of the aggregate remaining after the asphalt binder is burned off from the initial mass of the test sample.
