What is a rotary compactor? Let me tell you about it.

　　The rotary compactor is the preferred instrument for Junlin, professionally developed and manufactured for teaching and experimental purposes. The working principle of the rotary compactor is to simulate the in-situ, on-vehicle compaction of road surfaces, rotating and compacting asphalt mixtures in test molds to provide specimens for asphalt mixture testing.

　　1 Height: 190 cm

　　2 units: 370 kg,

　　3. Shipping weight: 410 kg

　　4. Mold weight: 7.4 kg

　　5. Outer diameter dimensions of the loading head: φ149.65mm ± 0.10mm, φ99.65mm ± 0.10mm

　　6 Pressure range: 200–1000 kPa, continuously adjustable

　　7. The uniform compressive stress applied by the loading device to the base plane of the test mold: Initially, during the first 0 to 5 cycles, the stress shall be 600 kPa ± 60 kPa; after more than five cycles, the stress should be maintained at 600 kPa ± 18 kPa.

　　8 Number of rotations: Forward rotation: 0–999 times; Reverse rotation: 0–999 times

　　9. Rotational compaction shear angle range: 0.5° to 2.0°, incrementing in steps of 0.01°. Before leaving the factory, the compaction angle is calibrated to achieve an effective external angle of 1.25° ± 0.02° and an internal angle of 1.16° ± 0.02°.

　　10 lateral displacement sensors with a measurement range of 0 mm to 200 mm, an accuracy of 0.1%, and a resolution of 0.05 mm.

　　Rotary encoder accuracy: 0.01 mm, resolution: 0.01 mm

　　11. Static straightness measurement indication error of the lateral displacement device: 0.1 mm +0.00 +0.00

　　12 Mold trial dimensions: Inner bore diameter: φ150-0.10mm; φ100-0.10mm

　　13 Rotational speed: 30 ± 0.05 (r/min)

　　Precautions:

　　1. Before performing the experiment, put on protective gear such as gloves to prevent the equipment from causing injury to your body during operation.

　　2. During the active experimental process, the program automatically completes the experiment (except in cases where an unexpected device failure causes automatic termination); typically, no manual intervention is required, thus preventing misoperations that could disrupt normal equipment operation.

　　3. The experimental door is equipped with a magnetic switch; the experiment cannot proceed unless the experimental door is fully closed.
