The asphalt content is determined by the binder fraction. A specially designed asphalt ignition furnace is heated to a chamber temperature of 538ºC (1,000°F) to ignite and burn the asphalt off of a loose HMA sample. This procedure is complete in about 30 to 40 minutes for samples from 1,200 to 1,800g, and slightly longer for samples up to 3,000g.
This procedure covers the determination of asphalt binder content of hot mix asphalt (HMA) by ignition of the binder in accordance with AASHTO T 308-10. Overview The sample is heated in a furnace at 538°C (1000°F) or less; samples may be heated by convection or direct infrared irradiation (IR). The aggregate remaining after burning can be

Distributors Asphalt that is applied at temperatures above flash point is especially vulnerable to combustion. For example, applying a prime coat with a distributor involves using cutback asphalt heated above its . flash point. If a fire starts at the spray bar it may . spread through asphalt deposits on the distributor . chassis and destroy ...
HOT MIX. As an asphalt binder modifier, the unique properties of Gilsonite ® uintaite make a road that is less susceptible to high-temperature and deformation performance issues. When these modified binders are used in recycled asphalt pavements, Gilsonite ® adds back what time has taken from the old asphalt, making it easier to use more of this recycled material.

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.
