For quantitative determination of bitumen content in paving mixtures
Centrifuge extractor operation requires relatively short time. Sample is weighed, heated slightly until is starts crumbling, cooled, placed in rotor bowl and solvent is added. Centrifugal action forces liquid through a filter paper ring at bowl's periphery, and process is repeated until expelled solvent is clear color. Aggregates are weighed and graded. Weight before and after extraction determines contituent proportions.
