This Fraass breaking point tester is composed of a brittle point tester and a low-temperature water bath. The brittle point tester is the main testing component, while the low-temperature water bath serves as the essential refrigeration equipment for cooling purposes.

The freezing room of the brittle point tester maintains a cooling rate of 1°C per minute. Equipped with an electric bending mechanism, the instrument loads the specimen automatically, ensuring the specimen is bent precisely once every minute.

The Asphalt Breaking Point Test operation panel features an LCD display, CANCODE, function switches, and a built-in printer. This design allows operators to manipulate the test easily and observe specimen results intuitively.

A layer of asphalt film is applied to a metal sheet of specific dimensions and placed into an insulation cylinder equipped with a cooling device. A handle is used to bend the metal sheet. As the temperature decreases, the asphalt film's temperature drops accordingly. When it reaches the point where the asphalt film breaks under the specified bending conditions, that temperature—indicated by the thermometer—is recorded as the brittle point of the asphalt.

The automatic asphalt brittle point tester utilizes a liquid crystal display and a user-friendly interface. Controlled by a single-chip microcomputer, the entire experimental process is automated, eliminating the need for manual supervision. It automatically detects parameter changes, obtains results, and includes a self-diagnosis function with operational prompts. It also features a built-in printer and an RS-232 output interface for data management.
