Once the asphalt is burned off, the remaining aggregate can be used for sieve analysis to check particle size distribution, though some degradation may occur during heating.

The sample is spread evenly across the basket assembly to maximize surface area exposure. The initial mass of the sample and baskets is recorded. The assembly is placed inside the preheated ignition furnace. Step 4: The Combustion Process astm d6307 pdf

The standard applies to both loose asphalt mixtures and samples taken from existing pavements. It is important to know that the D6307 test method determines the total asphalt content and can be used on a wide range of mixture types for various purposes.

Historically, determining asphalt content relied on chemical solvent extraction (such as chlorinated solvents like trichloroethylene). These chemicals posed severe health risks to laboratory technicians and created environmental disposal issues. The ignition method outlined in ASTM D6307 revolutionized the industry by offering a cleaner, safer, and faster alternative. 2. Core Principle of the Ignition Method

The method involves placing a sample of the asphalt mixture in an ignition furnace to burn off the asphalt cement Defines key terms like ignition furnace , correction
