Key Features

Two Models: Full-Spectrum Rheological Asphalt and Bitumen Testing

The popular SmartPave dynamic shear rheometers assess unmodified and modified asphalt binder and bitumen throughout a wide temperature range, either according to standards or using conventional rheological methods.

SmartPave 303 satisfies the highest measuring standards throughout the board.
SmartPave 93 is specifically developed to meet the demands of quality control and routine measurements in asphalt testing laboratories.

The Ultimate Rheometer Software

RheoCompass is the market-leading rheometer software, providing a comprehensive overview and deep insights. It includes various templates designed specifically for use with the dynamic shear rheometer in the asphalt industry.

The predefined test methods offer step-by-step instructions for all test types specified by AASHTO, ASTM, DIN EN, and FGSV. Templates are routinely updated to ensure users remain in compliance with the latest version of the standard.

Unique Accessories for Easy Handling

The SmartPave 93 and SmartPave 303 temperature control units are the first Peltier heating systems that include heating components above and below the sample, as well as the broadest temperature range.

Both instruments contain Toolmaster. It is the first entirely contact-free automatic tool identification and setup system for rheometers, recognizing measurement systems and temperature control units as soon as they are attached: No more manual data entry.

Fully Automatic Temperature Calibration

Temperature accuracy and stability are critical in asphalt testing.

Anton Paar's RheoCompass software provides completely automatic temperature calibration and verification methods. The SmartPave dynamic shear rheometer's automated calibration assures temperature gradients of <0.1 °C, making it ideal for asphalt processes.

Upgrade the SmartPave DSR to a BBR

Enhance the SmartPave 303 or 93 with a specialized software solution from Pavement Systems LLC, a collaborative partner. Connect seamlessly to this external analysis program and have access to a variety of functions, including iCCL testing.

This effective approach (a surrogate of BBR [AASHTO PP112]) gives low-temperature PG-grade, m-value, stiffness (S), and ΔTc data in under 30 minutes.

Experienced Experts on Hand
