Introduction and Applications of the Rotary Compaction Tester
2021-12-30
The rotary compactor, entirely developed and manufactured by Italy’s Matest, is designed to simulate and replicate the actual compaction conditions encountered during real-world road construction, thereby accurately determining the compaction characteristics of asphalt. This compaction process is carried out in a fully automated manner, with separate rotary motion and mechanical punch applying vertical load. The compactor features a high-strength structural steel frame that ensures exceptional angular control.
The load is transmitted through an electrically controlled cylinder, with precise pressure regulation achieved via servo control of a fine-tuned pressure regulating valve. The height is measured using a linear sensor. Rotational motion is generated by a high-precision eccentric cam system, which allows for easy and accurate angle setting and maintains a constant angle. The rotational speed is controlled by a computer via a frequency converter. With the use of appropriately designed perforated molds,
Usefulness
It is used to simulate the actual compaction conditions encountered during pavement construction practices, thereby determining the compaction performance of asphalt mixtures. It is also employed to evaluate the compactness characteristics of asphalt mixtures, providing support for the design, quality control, and testing of these mixtures.
Product Features
▍High-strength steel frame ensures excellent angle control and meets the stringent deviation requirements of ASTM/AASHTO and EN European standards.
▍Servo control valve controls electrical actions
▍The electronic control unit features a touch screen with color display, and its operating interface is similar to that of a PC running the standard Windows operating system. The device can also be operated via PC control software to perform experiments.
▍Data Acquisition and Processing Software
▍The touchscreen icons make it extremely convenient to set parameters, start automatic tests, collect data, generate graphs, and create test files. By directly connecting via Ethernet (to the LAN port), you can establish remote communication over Ethernet, enabling timely fault diagnosis and software upgrades by the manufacturer’s technical staff.
