2016-7-8 · DETERMINING UNIT MASS (WEIGHT) OF AGGREGATES TxDOT Designation: Tex-404-A Effective Date: August 1999 1. SCOPE 1.1 3This method describes the determination of the loose mass per m 3(ft. ) of both fine and coarse aggregates. 1.1.1 The unit mass of aggregate in a saturated surface-dry (SSD) condition is intended for use
Read More2002-1-15 · 3. Techniques for aggregate mass fractal dimension determination. A number of techniques have appeared in the literature to determine the mass fractal dimension of aggregates of fine particles. Here we give details on the three most common techniques: (light) scattering, settling and image analysis.

Laboratory experiment design 3.1 Material selection . South Africa has a fairly large geographic and geological footprint, resulting in great variety of aggregate types available for pavement construction.

Free water is simply the difference between the mass of a sample of wet-saturated aggregate and the mass of the same sample in the saturated-surface-dry condition. Standard test methods for surface moisture in fine aggregate are available (ASTM C70). What is the formula of moisture content determination?

If the mass must be determined to the nearest mg (or 0.001 g), use the electronic top-loader that is located in your lab. If the mass must be determined to the nearest 0.1 mg (or 0.0001 g), use an analytical balance in your lab.
