New specific gravity device to be debuted by Gilson

摘要

Gilson will be demonstrating its new SG-4 asphalt bulk specific gravity device, which is claimed to be the quickest and most accurate method for bulk specific gravity determinations of asphalt cores and gyratory specimens. The company said that the SG-4 uses a precision, computer-controlled system to measure water displacement with superior resolution and accuracy. It claims that this provides results that are considerably more reliable and repeatable than current methods. The dry weight of the asphalt specimen is entered and the sample is lowered into the measuring chamber, with the bulk specific gravity is displayed directly to the computer screen in seconds.
