  • Determination of the Asphalt Binder Content of

    Determination of the Asphalt Binder Content of

    The asphalt binder content is calculated by dividing the mass loss of the specimen after ignition by the mass of the bituminous mixture before ignition. A correction factor is determined for each bituminous mixture and then applied to the measured asphalt binder content of field produced bituminous mixtures. 4.
