4000ml with a rubber stopper and a tube to the vacuum: balance- accuracy of 0. 1, vacuum pump or water aspirator- maximum of 4kpa, residual pressure manometer or calibrated absolute pressure gage, manometer or vacuum gage, thermometers ix. Mechanical agitation device: astm d2726, balance, water bath, drying oven, thermometer, liquid-in-glass partial immersion thermometer, platinum resistance thermometer, metal-sheath thermistor, sample identification, asphalt content 5. 2% , g(sb)combined 2. 6, water temp. 69f, temperature of the cylinder during creation 325f: test specimen are within the astm d2726 and d2041 specifications, min of 1500g for 12. 5, test procedure. I found no deviations in the test procedure: astm d2041- rice method, separate the oven dry sample, avoid any uneven mix of fine aggregate and coarse aggregate in each pile. Place sample into the pot and fill with water (77f) to cover the sample completely. Cover the pot and agitate the sample (to remove trapped air bubbles) and vacuum the pot.
