Rotary Compactor: What are the features of an asphalt rotary compactor?

The YZM-150 rotary compactor is equipped with an 8-inch industrial touch screen featuring a Chinese-language interface, making it easy to set operating parameters and display process data in real time. For example, it can show the number of rotations, real-time pressure, displacement data, and density change curves. A computer interface is also provided as standard, allowing test data from the system to be downloaded onto a computer and stored and printed in Excel format as spreadsheets and trend charts. This machine is designed and manufactured based on imported equipment; its key original components—such as the pressure unit, sensors, and variable-frequency motor—are all genuine products. So, what are the features of the rotary compactor: the asphalt rotary compactor?

Rotary Compactor: What are the features of an asphalt rotary compactor?

This instrument is used to prepare specimens for determining the mechanical and volumetric properties of hot-mix asphalt mixtures. The specimens accurately simulate the density, aggregate arrangement, and structural characteristics of actual pavements under proper construction practices. This testing method can also be employed to monitor the density of specimens during the preparation process—thus serving as a tool for Superpave mixture design. Moreover, it can be utilized as an on-site control measure throughout the production process of hot-mix asphalt mixtures. The Troxler rotary compactor is manufactured according to SHRP specifications and has been approved by the Federal Highway Administration. The asphalt mixture specimens produced by this machine can reliably predict the long-term performance of pavements. The SHRP Superpave program uses the specimen height measured after each rotation during the compaction cycle as a key parameter for asphalt mixture design. Such data cannot be obtained from a Marshall compactor or any other laboratory equipment. During the compaction process, the Troxler rotary compactor automatically measures the specimen height and generates a compaction curve.

Rotary Compactor: What are the demolder and specimen mold lifter?

The rotary compactor is also equipped with a sample stripper that can be placed next to the compactor. The height of the stripper is adjustable, allowing operators to directly slide the test molds and compacted samples into the stripper. For users with limited space, the ejector can be installed in a movable manner or fixed permanently to the floor for added stability. To facilitate lifting fully loaded test molds, Troxler offers a mold lifter. The lifter’s sliding mechanism makes it easy to receive the test molds—primarily by using internal wheels to lift and move the molds.

Rotary compactor: What are calibration verification, data storage, and printing?

By using the compactor’s internal microprocessor and the tester’s accessories, you can simply calibrate and test the compactor’s settings 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.

Rotary Compactor: How to Operate It?

Press the individual control button to lower the piston, adjust the compaction angle, and record the data. Each sample is subjected to a constant compaction pressure, angle, and rotation speed, ensuring highly consistent samples. These parameters can also be easily modified by following the prompts in the drop-down menu.
