Introduction and Applications of the Rotary Compaction Tester
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 pavement construction, thereby accurately determining the compaction characteristics of asphalt. This compaction process is carried out in a fully automated manner, with separate rotational motion and mechanical pressure head applying vertical load. The compactor features a high-strength structural steel frame that ensures superior angular control.

Characteristics of the Asphalt Mixture Stability Tester
In view of the shortcomings or deficiencies inherent in the aforementioned prior art, the objective of this utility model is to provide a high-strength Marshall flow value testing setup. This setup utilizes standard Marshall test molds, shims, flow value sensors, and a signal switcher to perform flow value tests on Marshall specimens ranging from high strength to ultra-high strength. The utility model features a simple combination and convenient operation, enabling automatic digital display and measurement of the flow values for high-strength Marshall stability. By simply pressing a button on the display screen of the digital pressure testing machine, the readings of the stability flow values can be displayed separately, making this setup highly versatile and easy to use.
