Technical Parameters of the Asphalt Mixture Rotary Compactor
This device is suitable for molding cylindrical specimens of asphalt mixtures with diameters of 150 mm or 100 mm using the rotary compaction method, intended for laboratory testing of the physical and mechanical properties of asphalt mixtures. The molded specimens are used in tests such as compressive strength, shear strength, splitting, and rebound.

Features of the Rotary Compaction Tester
The rotary compactor is regarded as one of the better laboratory methods for compacting asphalt mixture specimens, used to evaluate the compaction characteristics and field performance of test specimens. Compaction is achieved by applying a vertical stress via end plates; the mold’s longitudinal axis rotates around a fixed pivot point at an angle relative to the vertical direction, while the upper and lower end plates remain parallel. During compaction, the specimen height is automatically measured, and the test density and air void content are calculated. The operator can select either a specific number of rotations or a target density or air void content to achieve during compaction.
