Technical Parameters of the Asphalt Mixture Compaction Tester
2022-02-24
The asphalt mixture compaction apparatus is suitable for preparing cylindrical specimens of asphalt mixture with diameters of 150 mm or 100 mm using the rotary compaction method, for use in laboratory tests on the physical and mechanical properties of asphalt mixtures. The molded specimens are used in tests such as compressive strength, shear strength, splitting, and rebound.
The device consists of a hydraulic pressurization system, a rotating base, a demolding system, a data acquisition system, a data display system, and control systems for deformation, angle, and other parameters.
Connecting to a computer allows for analysis and calculation of experimental data, data storage, and graphical display.
Features: The hydraulic system ensures stable specimen formation without any loosening or scattering. The built-in demolding system integrates molding and demolding into one convenient and efficient process.
Technical Parameters
1. Voltage: 380V (three-phase, four-wire)
2. Effective dimensions of the test cylinder: Φ150×200mm; Φ100×160mm
3. Vertical pressure exerted by the hydraulic cylinder on the specimen: The factory setting is 600 kPa ± 10 kPa (for Φ150 specimens) (for Φ100 specimens, adjust according to the instructions).
4. The hydraulic pump station’s rated pressure is 25 MPa.
5. Compaction rotation angle: 0–3 degrees; factory setting adjusted to 1.16° ± 0.02 degrees.
6. Number of rotations: 0–999 (adjustable)
7. Compaction speed: 30 r/min ± 0.5 r/min
8. Main unit external dimensions: 900*600*2250mm
9. Overall dimensions of the hydraulic system: 500*500*900mm
