The Reflux Extractor is designed to determine the asphalt binder content of bituminous mixtures using the hot solvent reflux extraction method. The apparatus complies with ASTM D2172 and AASHTO T164B, providing accurate and reliable asphalt content determination for laboratory quality control.
Reflux Extractor for Asphalt Binder Content Testing
The Reflux Extractor is designed to determine the asphalt binder content of bituminous paving mixtures using the hot solvent reflux extraction method.
The apparatus uses hot plates to generate solvent vapor that continuously circulates through a stainless steel wire mesh cone containing the test specimen. The heated solvent dissolves the asphalt binder while leaving the aggregate intact, allowing accurate determination of the bitumen content after extraction.
The system consists of a cylindrical glass extraction jar supported by a durable metal frame and includes stainless steel mesh cones, a hot plate heater, and a metal condenser to ensure efficient and repeatable extraction.

Reflux Extraction Method
The Reflux Extractor determines the asphalt binder content by continuously circulating heated solvent through the bituminous mixture.
As the solvent dissolves the asphalt binder, the aggregate remains inside the stainless steel mesh cone, allowing precise calculation of the asphalt content after extraction.
This internationally recognized method provides reliable, accurate, and repeatable results for asphalt mixture evaluation.
