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. Distributor: ELE International, Ltd. ELE International, Inc.

OPERATION A. Sample Preparation Follow the procedure outlined in ASTM D 2041 for separating the sample particles, oven-drying the sample, and cooling it to room temperature. B. Operation 1. Weigh the empty pycnometer without the lower water inlet hose and without the gauge and hose assembly on the top. Designate this weight as "B." 2. Place the prepared sample in the pycnometer and weigh the sample and pycnometer together, designating this weight as "C." The weight of the sample is A = C - B. 3. Install the gauge and hose assembly and connect the aspirator to both the pycnometer and the laboratory water faucet, as shown in Fig. 1. Note: Instead of the aspirator, a vacuum pump may be connected directly (through a water trap) to the hose. 4. With the water inlet valve closed, connect the water inlet hose to both the pycnometer and the laboratory water supply, as shown in Fig. 1. 5. To begin operating the aspirator, turn on the water faucet...
