VACUUM PYCNOMETER

MODEL 45-9300 (AP-132)

I.GENERAL INFORMATION

The 45-9300 (AP-132) Vacuum Pycnometer is designed to be used in determining the theoretical maximum specific gravity of bituminous paving mixtures, using the procedure described in ASTM standard test method D 2041 for type F containers. This large capacity (approximately 10 liters) unit can easily handle samples up to 13.2 lbs (6 kg), minimizing segregation effects. Constructed of lightweight polycarbonate, the

45-9300 (AP-132) Vacuum Pycnometer has a transparent top for easy visual observations of the vacuum effects.

II.RELATED USER DOCUMENTATION

These operating instructions do not contain all the required information for the standard test method used to determine the theoretical maximum specific gravity and density of bituminous paving mixtures. Please refer to ASTM D 2041 for additional information.

III.CALIBRATION

Calibrate the pycnometer by determining the mass of the container when it is filled with water at a range of temperatures, from 60 to 150°F (15 to 65oC), or as required. Prepare a graph with temperature vs. mass of the pycnometer filled

with water for the selected range of temperatures. Designate the mass of the container at 77 ± 0.9 °F (25 ± 0.5 °C) as "D." Refer to ASTM D 2041 for further assistance in calibrating and graph preparation.
