Abstract:
A method for analyzing material properties of a material sample comprising aggregate:obtaining a first aggregate material sample of a material undergoing analysis; drying the first aggregate material sample; determining the dry weight of the first aggregate material sample; providing a volumetric container, the volumetric container having a lid that attaches thereto that are configured together to be able to define a fixed or constant internal volume; partially filling the volumetric container with liquid; placing the first aggregate material sample in the volumetric container; adding additional liquid to the container after the first aggregate material is placed in the volumetric container; attaching the lid onto the volumetric container to enclose the liquid and aggregate material therein; measuring the weight of the volumetric container holding the first aggregate material sample and the liquid after the steps of attaching the lid and adding additional liquid; obtaining a second aggregate material sample of a material undergoing analysis; drying the second aggregate material sample; encasing the second aggregate sample in a vacuum-sealed second container; immersing the second aggregate material sample while it is held in the vacuum-sealed container in a liquid bath; opening the vacuum-sealed container as it is held immersed in the liquid bath; measuring the weight of the second aggregate material sample in the second opened container while they are held immersed in the liquid bath; and determining at least one of the percent absorption, apparent specific gravity, bulk specific gravity, and saturated surface dry (SSD) weight of the aggregate undergoing analysis based on the weights obtained in said measuring steps.
