Small Beam Bending Tester: What is the working principle of rotary compaction?
In our daily lives, there’s a type of machine—used for mix design—that’s compact yet durable, incredibly easy to move around, and comes equipped with a built-in mold angle measurement device. You can use this rotation feature to quickly check the quality of your mixes. Its extra-large capacity allows it to hold more mixtures at once, making it particularly convenient. It can also store important data from up to 20 experiments, and offers a variety of output options for you to choose from. So, do you know the main working principle behind the rotary compaction apparatus? Let’s get a reminder from the manufacturer of the beam bending tester!

Structure of the Low-Temperature Asphalt Material Strength Performance Instrument and Meter
Structure of the Low-Temperature Asphalt Material Strength Performance Instrument
Temperature-Controlled Chamber: The temperature-controlled chamber of the asphalt low-temperature performance testing instrument features a wide temperature control range, from -60℃ to +200℃. It can be used not only for testing but also for maintaining the integrity of asphalt material specimens. The chamber is equipped with microprocessor-based control and offers programmable constant cooling rate settings, with a maximum cooling rate of 40℃/h. The chamber boasts a spacious internal volume (400mm wide × 280mm deep × 300mm high), capable of accommodating at least four sets of ABCD specimens or four sets of ACCD specimens for testing.

The function of the low-temperature asphalt material strength performance tester.
The Function of the Low-Temperature Asphalt Material Strength Performance Tester
The low-temperature asphalt material strength performance tester is a new type of testing equipment used to evaluate the low-temperature cracking performance of asphalt binders or mixtures. Its primary purpose is to determine the temperature-strain curve of asphalt binders according to the AASHTO T387 Asphalt Binder Cracking Test Method (ABCD), thereby directly obtaining the low-temperature cracking temperature.

Uses and Features of the Low-Temperature Asphalt Material Strength Tester
Applications and Features of the Low-Temperature Asphalt Material Strength Tester
The low-temperature asphalt material strength tester can precisely control any loading rate. In addition to common mechanical tests on asphalt mixtures, it can also be used—with various instrument accessories—to measure the unconfined compressive strength and indirect tensile strength of diverse geotechnical specimens, as well as to determine the thermal stability and resistance to plastic flow—specifically, the stability and flow values (Marshall test)—of asphalt mixtures. All these tests require vertical loading.
