HA-1701.3F SmartPave 92 AASHTO Dynamic Shear Rheometer (DSR)

Description

Anton Paar SmartPave 92 Dynamic Shear Rheometers are configured to meet the demands of everyday quality control testing of 8mm and 25mm samples in asphalt production facilities. These models are ideal for classification of SHRP/SuperPave PG binders.

The synchronous, brushless DC motor drives a rotor mounted on a frictionless air bearing to allow the most precise movement and sensitive measurements. Maximum torque is 125 mNm (milliNewtons-meter) and minimum oscillation torque is 1μNm. Speed range is from 10-3 to 1,500rpm. A clean, dry, and oil-free supply of compressed air is required for operation. Operating air pressures are from 58 to 101psi (4 to 7bar) with optimum pressure of 87psi (6bar).

User-friendly RheoCompass™ software is included and designed specifically for the needs of the asphalt industry. It contains numerous templates that are tailored specifically to the needs of the asphalt industry. The predefined test procedures contain step-by-step instructions for all test types as defined by AASHTO, ASTM, DIN EN, and FGSV. RheoCompass™ software offers fully automatic temperature calibration and verification routines. Temperature accuracy and stability are crucial in asphalt testing. The unique automatic temperature calibration routine ensures temperature gradients <0.1 °C.

Toolmaster™ automatic tool recognition and configuration instantly recognizes testing components and temperature control units, eliminating the need to enter data manually when changing components. Quick-Connect coupling allows one-handed connection of key components and ensures fast, convenient changes. TruRay LED lighting feature provides a clear view of the sample and measurement surface for easy set up and precise filling of the measuring gap. A sliding rail design allows easy access to the sample during trimming and set up operations.

The HA-1700.3F is designed for everyday QC testing, and is supplied without the Peltier temperature-controlled hood. Upper and lower measuring plates and fittings for 8mm and 25mm samples are included. This cost-effective model does not fully meet ASTM and AASHTO requirements for total temperature control. The Peltier system in the base provides temperature control for the lower plate.

The HA-1701.3F is also configured for routine QC testing, but fully complies with current ASTM and AASHTO requirements for temperature control of the testing environment. The patented active Peltier temperature hood controls temperatures both above and below the sample, eliminating temperature gradients and making heating and cooling rates much faster. Test times are reduced, while reproducibility is improved. With no water flow around the sample, set-up and testing takes place in a completely dry environment. Temperature range is -5° to 200°C, with temperature gradients less than 0.1°C.
