I. Introduction

This Bending Beam Rheometer is based on the T 0627 asphalt bending creep stiffness test (Bending beam rheometer method) in the People’s Republic of China industry standard JTG E20 Highway Engineering Asphalt and Asphalt Mixture Test Regulations, and the SH/T 0775 asphalt bending creep stiffness test Method (BBR method).It also refers to AASHTO T313, AASHTO TP125, American Society for Testing and Materials ASTM D6648.Designed and manufactured by European EN 14771 standards, it is suitable for determining the low-temperature bending creep stiffness S(t) and creep slope value (m) of asphalt, and can be used to evaluate the low-temperature fracture characteristics of asphalt binders.

II. Feature

1. The industrial tablet computer is used to display the deformation curve, pressure curve and temperature curve in real time, and the instrument clock software can be set and adjusted.

2. Adopting PELTIE technology and refrigerating machine compound mode, the cooling speed is fast, and the temperature control accuracy is high.

3. Using linear differential displacement sensor (LVDT), equipped with standard calibration module, displacement parameters can be calibrated, accurate, and high precision.

4. Using high-precision load sensor, equipped with standard pressure calibration device, the pressure can be calibrated, accurate and reliable.

5. Bending Beam Rheometer adopts a high-precision, low-noise, split-body refrigerator, and connect it to the host with a hose to prevent its vibration from affecting the test results.

6. A magnetic stirrer with adjustable speed is installed in the liquid bath, and the temperature of the liquid bath is accurate and uniform.

7. Air source pressure, pre-pressure, load pressure and air bearing pressure can all be displayed intuitively and digitally in the operating software for easy viewing.

8. A USB communication port is designed to export the test data of the instrument.

9. Two-stage high-precision air filter is used to provide high-quality compressed air for the air suspension system to ensure detection accuracy.

10. This Bending Beam Rheometer has the functions of instrument overload protection, fault early warning, etc., when an abnormality occurs, the buzzer will alarm and the interface fault code will be displayed simultaneously.
