What are the features of the asphalt rotary compactor angle calibrator?

Features of the Asphalt Rotary Compactor Angle Calibrator: This instrument is used to prepare specimens for determining the mechanical and volumetric properties of hot-mix asphalt mixtures. The specimens simulate the density, aggregate distribution, and structural characteristics of actual pavements under correct construction practices. This test method can also be used to monitor the density during the specimen preparation process—making it a valuable tool for Superpave mixture design. Furthermore, it can be employed for on-site quality control during the production of hot-mix asphalt mixtures.

1. Demolding machine and mold-testing lift:

The rotary compactor angle calibrator is equipped with a specimen demolding device that can be placed next to the compactor. The height of the demolding device is adjustable, allowing operators to slide the test mold and the compacted specimen directly into the demolder. For users with limited space, the demolder can be moved and repositioned as needed. Of course, it can also be fixed to the floor for added stability. To facilitate lifting the test mold containing the sample, T

2. Factory Calibration:

The rotary compactor angle calibrator sets the pressure, angle, and rotation speed according to SHRP specifications. Users don’t need to assemble or calibrate it—simply power it on and start compaction.

3. Calibration check, data storage, and printing:

Using the internal microprocessor of the compactor and the tester attachment, you can easily calibrate and check the compactor settings right on-site. After each inspection, the measured values for pressure, angle, height, and rotational speed are automatically stored. The operator can choose to print either a single calibration result or a summary report covering all four parameters. Both reports display the date, time, and calibration results.

4. Gyropave data acquisition software:

The Troxler Gyropave software can be used to perform a more comprehensive analysis of compaction data from the rotary compactor angle calibrator, presenting the results either in tabular or graphical form. This software can calculate the design requirements for Superpave mixtures. The Gyropave software can also be used for on-site mixture verification. The SourceStar program does not require templates, spreadsheets, or any other software.

5. Data storage, output, and analysis:

The height of each compacted specimen shall be stored in the computer’s memory. The system can store and retain data for more than six sets until overwritten or deleted. After each rotation during the compaction cycle, the height of the specimen can be automatically output directly to a printer or computer. Additionally, the data stored after compaction can also be downloaded to a computer or printer.

6. Advanced Angle Method:

A new angle-guidance method is adopted. When the guide angle of the test mold base deviates, the top of the test mold is clamped in a fixed position, and this angle is generated by rotating the offset test mold base. As a result, moving parts and wear are significantly reduced.

7. Simple operation:

Press the individual control button to lower the piston (plunger), adjust the compaction angle, and record data. Each specimen is consistently prepared under constant compaction pressure, angle, and rotational speed. You can also easily modify these parameters by selecting from the drop-down menu.

8. Operator safety and low noise:

The design of the rotary compaction apparatus angle calibrator takes operator safety into account. All rotating components are housed beneath the workbench surface, keeping them away from the operator. The door and access panel are equipped with safety switches to further enhance operator safety when moving the specimens. The software can continuously monitor operations.
