A sample of aggregateis soaked in water for 24 hours and dried back to the SSD condition. A 500-g sample of the SSD materialis placed in an empty flask; water is then added to the constant volume mark on the flask, and the weight of the flask filled with both aggregate and water is measured to be 938 g. In comparison, the weight of the flask with only water filled to the constant volume markis weighted as 623 g. The aggregate sample is the noven-dried and the weight of the dry aggregateis measured to be 495 g. Calculate the specific gravity values, including bulk dry specific gravity, bulk SSD specific gravity, and apparent specific gravity.
