Understanding ASTM D6307: The Standard for Asphalt Binder Content by Ignition Method
. The furnace must feature an internal balance capable of weighing the sample up to with an accuracy of 2. Sample Basket Assembly
Safety gear (heat-resistant gloves, face shield, safety shoes). A mechanical split-sampler or quartering device. A cooling cage to protect technicians from hot samples. A forced-draft oven for pre-drying aggregate specimens. Step-by-Step Test Procedure
, describes a procedure for determining the amount of asphalt binder in pavement samples by burning off the cement in a high-temperature furnace. This method is a popular, solvent-free alternative for quality control and mixture evaluation. SIST e-Poslovanje Accessing the PDF The official, current version of the standard is ASTM D6307-19 astm d6307 pdf
For professionals in the petrochemical industry, accessing the ASTM D6307 standard in PDF format can be highly beneficial. The PDF version offers several advantages:
Before the widespread adoption of the ignition method, laboratories relied heavily on solvent extraction techniques (such as those outlined in ASTM D2172). Solvent extraction used chemical solvents like trichloroethylene or methylene chloride to dissolve and separate the binder from the aggregate.
This involves running a "calibration sample" of known composition through the furnace before testing unknown field samples. Conclusion Understanding ASTM D6307: The Standard for Asphalt Binder
Understanding ASTM D6307: Standard Test Method for Determining the Air Content of Freshly Mixed Concrete by the Pressure Method
. This process involves heating a sample in an ignition furnace to burn off the asphalt cement, allowing technicians to calculate the binder percentage by comparing the sample's weight before and after ignition. ASTM International Core Objectives and Scope
The primary source for the official PDF, including the current standard D6307-19 or previous versions like D6307-16 . A mechanical split-sampler or quartering device
If the sample contains moisture, it must be dried to a constant mass, or a separate moisture determination test (such as ASTM D1461) must be conducted to correct the final calculation.
If you are planning to use ASTM D6307 for testing, ensure you have the following:
Once the burn is complete, the sample is removed, allowed to cool to room temperature, and weighed. The total percent loss is calculated and adjusted using the previously established Aggregate Correction Factor to give the true asphalt binder content. Equipment Required for ASTM D6307 Compliance
