Basic Overview of the Asphalt Mixture Stability Tester

　　Overview of the Asphalt Mixture Stability Tester
　　This instrument has been developed and designed in accordance with the standard for stability tests of asphalt mixtures. It is suitable for both stability tests and submerged stability tests, and can be used for mix design of asphalt mixtures or for quality inspection of asphalt pavement construction.

　　Instrument composition:
　　The stability tester comprises a main unit, a force-measuring device, a flow-value measuring device, a printing device, and related accessories, all designed for measuring stability and flow value during testing. Moreover, with only minor modifications to the main unit of this testing instrument and the addition of appropriate accessories, it can be used to perform a variety of tests that require the application of vertical loads.

　　Features:
　　1. It can perform functions such as automatic loading, automatic shutdown, data display, data acquisition, peak detection, peak hold, and data printing.
　　2. The circuit adopts separation of high-voltage and low-voltage circuits, as well as separation of digital and analog signals. All electronic components are of ** quality, featuring a wide operating temperature range, stable performance, excellent repeatability, and strong anti-interference capability.
　　3. Equipped with triple self-protection features—hardware, software, and firmware—to ensure the safety and reliability of the testing process. The entire unit boasts a sleek appearance and is lightweight.
　　4. It adopts a modular design approach, with each functional module being relatively independent, making repair and maintenance easier.
