Softmatic is Matest’s automatic ring and ball apparatus for measuring the softening point of bitumen, asphalt and pitches according to EN 1427, ASTM D36, AASHTO T53 and other national standards. Dual laser sensors detect the ball drop precisely, the heating plate keeps a constant gradient of 5 °C/min and forced-air cooling shortens the time between tests.
The microprocessor-controlled heating plate maintains a constant temperature gradient of 5 °C/min, fully compliant with international Standards. An integrated magnetic stirrer guarantees uniform bath temperature, while the forced-air cooling system significantly reduces cycle times, allowing multiple tests per day.
The intuitive touch-screen interface (800×480 px) simplifies parameter setup, data management and result visualization, offering advanced tools for test analysis and storage.
Softmatic supports two testing conditions:
Built with a ceramic-glass heating plate and advanced safety features, the unit ensures stable operation and full automation from pre-heating to test completion.
What is the ring and ball test?
Two brass rings filled with bitumen, each carrying a steel ball, are heated in a liquid bath at 5 °C/min. The softening point is the temperature at which the bitumen becomes soft enough to let the balls fall through a defined distance. Softmatic detects the drop with laser sensors and records the temperature automatically, with no operator reading.
Power supply: 230V 1ph 50-60Hz 700W
Dimensions: 435x330xh510 mm
