A centrifuge extractor is a laboratory device used to determine the bitumen content in bituminous mixtures, such as asphalt used in road construction, by separating bitumen from aggregates using a solvent and centrifugal force. Below is a concise overview based on standard practices and available information.

Bitumen, a viscous, black semi-solid form of petroleum, is a key binder in asphalt mixtures used for road paving and construction. Determining its exact percentage in these mixtures is essential for quality control, ensuring durability and performance. The centrifuge extractor is a specialized laboratory device designed for this purpose, using centrifugal force to separate bitumen from aggregates (like sand and gravel) via a solvent.
