Binder Content – Pavement Interactive

The ignition test is the most common method used to determine HMA asphalt binder content. In the ignition method the HMA is heated in an oven (Figure 1) sufficiently to burn the asphalt binder within the mixture. The difference in weight before and after burning in the ignition oven gives a measure of asphalt binder content.
