The "ASTM D6307 PDF" is more than just a digital file; it is the blueprint for a reliable, safe, and efficient asphalt testing method. While it is tempting to search for a free copy, the risks of using an unauthorized, outdated, or incorrect version far outweigh the cost of purchasing the official document from ASTM International.
To measure this accurately, state departments of transportation (DOTs) and civil engineering laboratories worldwide turn to the standard.
While the method eliminates solvent hazards, it involves high temperatures and potential fumes . Key safety concerns include burns from the hot furnace and exposure to combustion byproducts. The user is responsible for establishing appropriate safety, health, and environmental practices, including the use of protective gear and ensuring proper ventilation. astm d6307 pdf
The asphalt mixture sample is warmed and split to the appropriate testing size dictated by the nominal maximum aggregate size (NMAS).

By weighing the sample before and after the ignition process, the laboratory calculates the exact percentage of asphalt binder lost during the burn. Key Components of the ASTM D6307 Test Procedure
The sample is placed in the furnace and heated. The ignition oven burns off the asphalt binder. The test concludes when no further mass loss is detected over a 3-minute period. 4. Cooling and Final Weight While the method eliminates solvent hazards, it involves
According to the standard:
The test procedure involves several steps:
