International 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 lightw

International IV. 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."

International 8. Open the water inlet valve to fill the pycnometer to the very top without leaving any air space. Be careful not to turn off the vacuum. Close the water inlet valve. 9. Using the quick-disconnect, detach the gauge-hose assembly from the top of the pycnometer. 10. If there is any air trapped in the pycnometer, reconnect the aspirator and vacuum gauge (using the quick-connect) and let more water in. 11. Close the water inlet valve. 12. Disconnect the water inlet

International 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:

International A. Pycnometer Not Getting Vacuum 1. Check 'O' ring to make sure it is clean and in good shape. If not, contact ELE/Soiltest for a replacement 'O' ring. 2. Check to make sure the water inlet valve is on tight. 3. Tighten the stopcock nut (at bottom of stopcock) of the water inlet valve. B. Air Bubbles Entering from the Water Inlet Valve 1. Check to make sure the water inlet valve is on tight. 2. Tighten the stopcock nut (at bottom of stopcock) of the water i
