ASTM standard asphalt content and binder ignition oven

STANDARD: ASTM D6307-98 AND AASHTO T308-99
Description:

    The Asphalt Content/Binder ignition oven with internal automatic balance is an environmentally-friendly and costeffective
method for the accurate determination of asphalt content.
    It is made of three parts: combustion device (furnace), weight measurement (electronic balance), test control and data processing (microcontroller unit).
    At the bottom of the chamber there are four dia. 30mm tube ports. They are for four dia.16mm cast synthetic micabars attached under a cordierite-mullite tray to get through the chamber, so that the tray can connect with the balance which could monitor the reduction in weight of the sample.
    Put the sample plate or basket on the tray for sample placement.
Above the furnace chamber there is fumes assembly chamber where the fume mixes with air before exhausted through the flue by the fan.
    Features
• Using the microcontroller unit and high degree of accuracy electronic balance, it is simple and easy not only to use but to maintain.
• Accurate endpoint detection according the pre-set calibration factor.
• Using new type furnace structure, heating up fast, short test time.
• New and beautiful appearance design. Furnace and balance accurate positioning for ensuring the sample center is located in the middle of balance.
• To every type of need-to-test asphalt mixture, with reference to standard technical require of American ASTM D6307-98 and AASHTO T308-99, use calibration sample to determine calibration system of asphalt mix to ensure credibility of the test result.
