Overview
Product Overview
The AELAB SYD-0627 is an Asphalt Bending Beam Rheometer (BBR) designed to measure the low-temperature bending creep stiffness S(t) and creep slope m value of asphalt binders. These measurements can be used to evaluate the low-temperature fracture characteristics of asphalt binders.
The catalog specifies T 0627 asphalt bending creep stiffness testing in JTG E20 and SH/T 0775 Determination of Bending Creep Stiffness of Asphalt (BBR Method). It also references AASHTO T313, AASHTO TP112 and ASTM D6648, and identifies EN 14771 among the European standards used for the instrument design.
The SYD-0627 is suitable for original asphalt, asphalt aged after pressure aging, and asphalt aged after a thin film oven or rotary thin film oven procedure.
The temperature-control system combines PELTIE technology with a refrigeration machine. According to the catalog, the bath can cool from room temperature to -18℃ in 40 minutes. A separate low-noise refrigeration unit connects to the main unit by hose to reduce the influence of refrigeration-unit vibration on test results.
Measurement is supported by an LVDT displacement sensor with a standard calibration module and a high-precision load sensor with a pressure calibration device. The liquid bath includes magnetic stirring, while the operating software digitally displays air-source pressure, pre-pressure, load pressure and air-bearing pressure.
Key Features
- Industrial Tablet Computer Control: The instrument control unit uses an industrial tablet computer for test operation.
- Rapid Composite Cooling: PELTIE technology and refrigeration-machine cooling can reduce the temperature from room temperature to -18℃ in 40 minutes.
- LVDT Displacement Measurement: Uses a linear differential displacement sensor with a standard calibration module for displacement calibration.
- Split Refrigeration Unit: A high-precision, low-noise refrigeration unit connects to the main unit through a hose to reduce vibration influence during testing.
- Load Sensor Calibration: High-precision load sensors are supplied with a standard pressure calibration device.
- Magnetically Stirred Liquid Bath: The host bath includes a magnetic stirrer to support uniform bath temperature.
- Digital Pressure Display: Air-source pressure, pre-pressure, load pressure and air-bearing pressure are displayed in the operating software.
- USB Data Export: A USB communication port allows instrument detection data to be exported.
- Overload and Fault Protection: Abnormal conditions trigger a buzzer alarm and display a fault code on the operating interface.
- Adjustable Test Time: Test time can be set for deformation verification, with a default value of 240 seconds.
- Selectable Result Calculation Times: Software calculation times are available at 8s, 15s, 30s, 60s, 120s and 240s by default.
- Air-Bearing Loading Shaft: The loading shaft uses air bearings with two-stage high-precision air filtration to provide low-damping loading.
