Understanding ASTM D6307: The Standard for Asphalt Content by Ignition

: The aggregate left after the test can be used for sieve analysis, though some degradation in particle size may occur depending on the aggregate type Alternative Methods : While D6307 uses heat, ASTM D2172 astm d6307 pdf

7. Calibration and Standardization

Describes how to determine the correction factor for the aggregate being used. This is a critical step because some fine aggregate particles (less than 75 µm) can burn off or be carried away by the exhaust system during ignition. Understanding ASTM D6307: The Standard for Asphalt Content

2. Scope and applicability

  • Applies to hot‑mix asphalt paving mixtures and pavement samples.
  • Heating may be by convection or direct irradiation.
  • Aggregate recovered can be used for sieve analysis (but some aggregates may degrade).
  • Provides two methods: Test Method A (furnaces with internal automated weighing) and Test Method B (furnaces without internal weighing).
  • The aggregate source changes
  • The aggregate gradation changes significantly
  • The ignition furnace is replaced or undergoes major repair

What is ASTM D6307?

ASTM D6307 is the standard test method for determining the asphalt binder content of hot mix asphalt (HMA) by the ignition method. Applies to hot‑mix asphalt paving mixtures and pavement

In addition, your laboratory should be accredited under ASTM D3666, which specifies minimum requirements for testing agencies performing asphalt mixture testing.
