Probe deflection rheometer.
It allows complete analysis without the use of external thermostatic baths, cooling the TE-BBR bath by means of the Peltier effect (thermoelectric effect).
Peltier cell cooling achieves temperature stability better than 0.1º C without the use of external pumping of flammable liquids.
Equipment designed to measure the rheological properties of asphalts specified in the latest revision ASTM D 4 - P 245 - AASHTO TP1 and SHRP B-002:
Modulus of rigidity.
Logarithm of the slope of the slow-slip curve.

Method of measurement:

Recommended by SHRP (Strategic Highway Research Program) for the study of asphalt specifications. The test basically consists of:

Application of constant load in the center of an asphalt specimen for a selected period.

Continuous monitoring of deflection.

Load and deflection graph obtained during the test.

Pneumatic pressure regulators allow the operator to adjust pressure in the main inlet line

Windows-based operating software. Controls the entire testing process and provides visualization of stress and strain. Reports and graphs can be printed on any Windows® compatible printer.

Solid-state Peltier cooling, no pressurized refrigerants required (air-water heat exchanger included)

Integrated, self-contained liquid bath that is cooled using methanol or ethanol:

Volume: 5 liters

Liquid circulation by means of magnetic stirrer with adjustable speed in panel.

Test tube, stand, etc …, immersed in a constant temperature bath.

Continuous compensation of the Archimedean thrust.
