D6307 Standard Test Method for Asphalt Content of ... - ASTM
The official document, ASTM D6307-19, provides the current technical specifications for this procedure.
ASTM D6307 is the globally recognized standard for determining the asphalt content of paving mixtures using the , a faster and more environmentally friendly alternative to traditional solvent extraction . By heating asphalt samples in a specialized furnace, this method burns off the binder, allowing for the precise measurement of residual aggregate.
: It eliminates the need for hazardous solvents and allows the recovered aggregate to be reused for gradation analysis (per ASTM D5444). The Ignition Test Procedure
: Intended for furnaces without an internal scale, requiring manual weighing before and after the ignition process.
The process involves several critical steps to ensure accurate and repeatable results.
The primary goal of ASTM D6307 is to quantify the amount of asphalt cement in a mixture for quality control and specification acceptance.
: Designed for furnaces with an internal, automated weighing system that tracks mass loss in real-time and provides a printed report.
