TILT TEST
The instrument measures the roughness coefficient of a joint.
The unit is also designed to test the possible fluage tendency of bituminous mixtures covering a slope of a dam subject to high sun radiations.
The fluage tendency is the permanent viscous deformation of a material.

AUTOMATIC DIGITAL RING AND BALL APPARATUS
This “high tecnology” digital microprocessor tester, designed and manufactured by Matest, automatically determines the softening point of asphalts and pitches.
Two laser sensors detect the balls fall determining the softening point.
The bath temperature is measured by an electronic system maintaining the gradient (5°C./min) as specified by the Standards.
A magnetic stirrer with electronic speed adjustment from 0 to 160 rpm also ensures an uniform temperature in the vessel during the test execution.
Two test parameters can be selected by the microprocessor menu:
- test on boiled distilled water for softening point from 30 to 80°C.
- test on glycerol for softening point from 80 up to 150°C.
Language selection: English, French, Spanish, German and Italian.
Functions of: clock calendar, test number, user/customer name, general notes, start/end of the test.
Real time visualisation of the bath temperature, test progress, rpm of the stirrer.
The tester is basically composed by:
- Ceramic-glass heating plate with automatic cut off at the end of the test cycle.
- Graphic high resolution display, 320x240 pixels with membrane keyboard.
- The microprocessor, through a friendly driven menu controls all the selected parameters of the: heater/stirrer, temperature probe, laser sensors, pre-heating phase of the plate, records all results in its permanent memory, storing up to 300 tests.
RS 232 port for PC download.
