    • A method of determining liquid absorption of an aggregate comprises providing a shaker apparatus, a vacuum source and a container; placing a sample of the aggregate in the container; adding liquid to the container sufficient to reach a calibration mark on the container; weighing the sample and liquid; mounting the container to the shaker apparatus; connecting the vacuum source to the container; agitating the sample and liquid with the shaker apparatus; applying a vacuum to the sample and liquid with the vacuum source; after the agitation and vacuum steps, adding liquid to the container sufficient to again reach the calibration mark on the container; again weighing the sample and liquid; and subtracting the initial weight of the sample and liquid from the final weight of the sample and liquid in order to determine the liquid absorption of the aggregate.
    • 确定聚集体的液体吸收的方法包括提供振动器装置,真空源和容器; 将集料样品放在容器中; 向容器中加入足以达到容器上校准标记的液体; 称量样品和液体; 将容器安装到振动器装置上; 将真空源连接到容器; 用振动器装置搅拌样品和液体; 用真空源对样品和液体施加真空; 在搅拌和真空步骤之后,向容器中加入足以再次达到容器上校准标记的液体; 再称重样品和液体; 并从样品和液体的最终重量中减去样品和液体的初始重量,以确定聚集体的液体吸收。
