LABORATORY CHARACTERIZATION OF ASPHALT

LABORATORY CHARACTERIZATION OF ASPHALT

Characteristics of Aggregates: Shape, Size & Specific

The Fine Aggregate Test (ASTM C128 and AASHTO T 84) is a comparison of sample masses in oven-dry, saturated surface-dry (SSD), and immersed conditions. This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is needed.
