ASTM D6307 is an internationally recognized standard test method titled "Standard Test Method for Asphalt Content of Asphalt Mixture by Ignition Method." It defines a precise procedure for determining the asphalt binder content in asphalt mixtures (like hot-mix asphalt) by igniting and burning off the binder in a specialized furnace. This method provides a quantitative measure of the asphalt content in a mixture for quality control, specification acceptance, and mixture evaluation studies.

After the binder is burned off, the remaining aggregate is completely clean. This allows technicians to perform a subsequent sieve analysis (ASTM C136) to verify that the aggregate gradation meets the design specifications. astm d6307 pdf

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.

Stainless steel sample baskets with mesh openings to hold the mix while allowing airflow. 2. The Correction Factor (Crucial Step)

The raw percentage of weight loss is calculated. The pre-determined aggregate correction factor is subtracted from this raw value to yield the final, corrected asphalt binder content percentage. The test is vital for ensuring that the

The ASTM D6307 PDF outlines two primary testing paths: (using an automated internal balance system) and Test Method B (using manual external weight measurements). The general workflow consists of the following steps: Step 1: Preparation of the Sample

This is the primary source for the most current version.

The official document, ASTM D6307-19, provides the current technical specifications for this procedure. After the binder is burned off, the remaining

Different aggregate types lose varying amounts of mass when subjected to extreme heat due to the burning of internal minerals or moisture. ASTM D6307 requires the determination of an .

High-temperature heat-resistant gloves, a full-face shield, and a well-ventilated fume hood or exhaust system to safely vent combustion gasses. The Step-by-Step ASTM D6307 Testing Procedure

is the Standard Test Method for Fill Power of Down Feathers. "Fill power" is a measure of the loft or "fluffiness" of down that is directly related to the insulating value of the product. Higher fill power means the down traps more air, providing better insulation with less weight.
