Product Overview:
- The Automatic Fraass Breaking Point Tester is a sophisticated laboratory instrument designed for determining the Fraass Breaking Point of bituminous materials in accordance with EN 12593, IP 80, JIS K 2207
- The Fraass Breaking Point represents the temperature at which a bituminous material tends to crack or break rather than deform or flow under specified cooling and bending conditions. This critical parameter is widely used for evaluating the low-temperature flexibility and brittleness characteristics of bitumen and bituminous binders, particularly for pavement and roofing applications subjected to cold climatic conditions.
- The system employs microprocessor-based automatic control to regulate cooling and sample bending operations, ensuring accurate, repeatable, and operator-independent test results.
- Designed with integrated temperature control, automated timing, and digital display, the instrument enhances testing efficiency while minimizing manual intervention.
Principle of Test:
- The Fraass Breaking Point test determines the temperature at which a thin film of bitumen coated on a standardized steel plaque fractures when subjected to repeated bending during controlled cooling. The specimen is cooled at a specified rate while being periodically flexed until cracking occurs. The corresponding temperature is reported as the Fraass
Breaking Point:
This test is an important indicator of:
- Low-temperature cracking resistance
- Flexibility characteristics of bitumen
- Suitability of binder for cold climate applications
- Thermal stress behaviour of bituminous materials
Key Features & Advantages:
- Fully Automatic Test Operation : The instrument incorporates microcomputer-controlled automation for precise management of cooling and bending cycles, reducing operator influence and ensuring high repeatability.
- Simultaneous Multi-Sample Testing : The system is capable of performing three tests simultaneously under identical environmental conditions and automatically calculates the average test value, improving productivity and testing reliability.
- Automatic Cooling Rate Control : The cooling cycle is automatically regulated through a computer-controlled low-temperature circulation bath, maintaining the prescribed cooling rate required by the standard.
- Automatic Sample Bending & Timing : The tester includes automatic timing and specimen bending functions, ensuring uniform application of stress during testing and accurate determination of breaking temperature.
- Digital Monitoring & Display : The test process and measured parameters are displayed on a colour LCD screen, enabling real-time monitoring and simplified operation.
- Built-in Test Report Printing : The integrated printer provides convenient documentation and immediate output of test results for laboratory records and quality control purposes.
- Customizable Temperature Range : The system can be supplied with an extended low-temperature measuring capability for specialized testing requirements.
