Describes how to determine the 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. astm d6307 pdf

Understanding ASTM D6307: Asphalt Content by Ignition Method

A complete, official copy of ASTM D6307 cannot be legally obtained for free. ASTM International maintains exclusive copyright over its standards. Accessing the full document requires a purchase.

Specific specimen weight tables categorized by aggregate size. This is a critical step because some fine

are closely related test methods. They both use the ignition method to determine the asphalt binder content of hot-mix asphalt (HMA). The National Center for Asphalt Technology (NCAT) was instrumental in the development of both standards, and many ignition furnaces are designed to be compliant with both. The two standards are currently undergoing a harmonization effort to align their procedures as much as possible, as documented in ASTM Work Item WK97915.

The standard, titled "Standard Test Method for Asphalt Content of Asphalt Mixture by Ignition Method," provides a universally accepted laboratory procedure to determine this vital metric. Engineers, technicians, and laboratory managers frequently seek out the ASTM D6307 PDF to implement proper testing protocols and maintain regulatory compliance. 1. What is ASTM D6307?

: Requires a specialized ignition furnace, internal balance (accurate to ), and safety equipment. Sampling and Preparation

Historically, asphalt content was determined using solvent extraction methods (such as ASTM D2172). While accurate, chlorinated solvents like trichloroethylene present significant environmental, health, and disposal challenges.
