Astm D6307 Pdf !full! May 2026
ASTM D6307 outlines the ignition method for determining asphalt binder content in mixtures by burning samples at approximately 540°C, providing a solvent-free alternative for quality control. The procedure requires an ignition furnace, sample baskets, and calculates the corrected binder content based on weight loss. For the full standard, purchase the document from ASTM International.
ASTM D6307 is the standard test method for determining the asphalt binder content of hot-mix asphalt (HMA) by burning it off in a furnace at approximately 540°C. The procedure provides a safe, solvent-free alternative for quality control and allows for subsequent sieve analysis on the remaining aggregate. Purchase the official standard at ASTM International

It works by removing the asphalt cement from the mixture in an ignition furnace Heating Methods: astm d6307 pdf
The process can use either the convection method or the direct irradiation method. Secondary Use:
Once the asphalt is burned off, the remaining aggregate can be used for sieve analysis to check particle size distribution, though some degradation may occur during heating.

For heavy-duty paving, high-viscosity grades like AC20 (viscosity measured at 60°C) are often used. 3. Key Procedures
The test is vital for ensuring that the produced asphalt matches the Job Mix Formula (JMF)
, which specifies the exact percentage of aggregate and bituminous material required for a project. AsphaltPro Magazine Sample Preparation: ASTM D6307 outlines the ignition method for determining
Samples are placed in a furnace and heated until all organic binder is burned away. Calculation:
The difference in mass before and after ignition (corrected for an aggregate calibration factor) determines the asphalt content percentage. Compaction Context:
Proper binder content is essential for achieving standard compaction rates, which are typically 5–6 mm per 25 mm of laid thickness. s7d2.scene7.com 4. Related Standards
