Binder Content

ASTM D6307-98, AASHTO TP53-95, AND BS The Carbolite Asphalt Binder Analyzer is fully compliant with the latest ASTM D6307-98, AASHTO TP53-95 and BS standards specifying equipment and procedures in determining the asphalt binder content of hot mix asphalt/bituminous mixtures by the loss on ignition method. This method replaces the traditional solvent procedure and thereby not only avoids the health and environmental concerns associated with chlorinated solvents, but also the related expense of such chemicals.

The CABA 7/35 Asphalt Binder Analyzer combines a sophisticated furnace and weighing system to continuously measure the weight loss of a bituminous mixture during combustion, and automatically calculates its binder content at the end of the test.


The use of double skin construction ensures a safe and cooler outer case temperature.
• The analyzer is designed for use as either a bench mounted model or can be positioned on an optional work height support stand.
• A door safety switch cuts power to the elements when the door is opened and a 180° opening side opening door allows complete access to the chamber opening.
• Low thermal mass insulation ensures that the furnace, rated at 750°C, is ready for use in approximately 20 minutes. This rapid heat up time allows the unit to be switched off in between tests and eliminates the need for a 24 hour timer.
• Exposed element coil are recessed from the chamber opening and have the advantage of increased life due to lower element loading and the reduced risk of contamination build up on the element surface.
• An independently controlled after burner significantly reduces furnaces emissions. The unit is designed to be fully compliant with the relevant standards, without requiring a filter system, there by eliminating maintenance to clean filters.
• The analyzer is supplied with two sets of sample trays, loading handle, cooling cage and printer paper. The furnace is rated for 8kW for operation on 208/240V, 50/60Hz, three phase or single phase, and the furnace holding power is approximately 3kW.
• The balance pan extension in the furnace chamber ensures that the sample tray is guided into position and is positively located within the chamber, ensuring ease of loading/unloading and preventing contact with the elements.
• The balance is easily calibrated using standard weights. A lift compensation factor allows for the lift created by the volatile extraction fan and reduced air density


Automatic door locking during testing which cannot be disabled by interruption of the power supply once the test has commenced.
• Door safety switch isolates - power to the elements when the door is opened.
• Independently controlled after burner significantly reduces furnace emissions.
• Eliminates health and environmental concerns related to the use of chlorinated solvents


The ability to automatically calculate and use calibration factors based on both asphalt mixes and dry aggregates Unique automatic input of sample start weight via an optional second external Ohaus balance which eliminates operator error.
• Rapid heat up rates permit the unit to be switched off between tests, resulting in reduced power consumption and eliminating the need for a 24-hour timer.
• Customization of test parameters and ability to save named test setups in a library.
• Choice of print format either continuously throughout the test showing the results at minute intervals or a final end of test analysis.
• Permits large sample sizes (up to 4.5 kg) to be tested.
• Precise measurement - weights measured to 0.1g.
• User friendly design.
• Cost savings due to reduction in testing time and elimination of costly chemicals
