V.CALCULATIONS

If the test temperature is within +3° or -5°F of 77°F (+ 1.7° or - 2.8°C of 25°C), the following equation can be used to determine the maximum specific gravity of the sample, with an error of 0.001 points or less due to thermal effects:

Where:

A = Mass of the dry sample in air (grams)

D = Mass of container when filled with water at 77°F (25° C) (grams)

E = Mass of container filled with both water and sample at 77°F (25°C) (grams)

Note: If the test temperature differs significantly from the recommended 77°F (25°C), the formula should be adjusted for thermal effect as follows:

Where:

A = Mass of dry sample in air (grams)

F = Mass of pycnometer filled with water at test temperature (grams)

G = Mass of pycnometer filled with both water and sample at test temperature (grams)

H = Correction for thermal expansion of bitumen (grams)

dw = density of water at test temperature, Mg/m3

0.9970 = density of water at 77°F (25°C), Mg/m3

Values of H and dw may be obtained from the ASTM graphs in Fig. 2. For more details, see ASTM D 2041.
