Determinination of the rheological properties of bitumenous mixtures bitumen penetration grade 70/100 and rubberr VR 15% using a Dynamic Shear Rheometer (DSR) Anton Paar RheoCompass™, according AASHTO T 315 standard were done. This test method covers the determination of the dynamic shear modulus and phase angle of asphalt binder when tested in dynamic (oscillatory) shear using parallel plate test geometry. It is applicable to asphalt binders having dynamic shear modulus values in the range from 100 Pa to 10 MPa. In this experiment the range in modulus is obtained between 76 - 94°C temperature and was repeated at 76 - 94°C temperature on the same day. An angular frequency of 10 rad/s. This test method is intended for determining the linear viscoelastic properties of asphalt binders as required for specification testing and is not intended as a comprehensive procedure for the full characterization of the viscoelastic properties of asphalt binder. First TEST RESULTS: Mean frequency: 10.0 rad/s = 1.59 Hz Mean strain: 12.06 % Mean shear stress: 0.085 kPa Mean phase shift angle: 75.3 ° Mean complex shear modulus |G*|: 0.706 kPa Mean temperature lower plate: 94.0 °C Mean temperature sample: 94.0 °C ANALYSIS RESULT: Number of data points: 10 |G*|/sin(δ): 0.7302 kPa Standard deviation: 0.0015 kPa Median: 0.7300 kPa Confidence interval (95 %): 0.7291 ... 0.7312 kPa AASHTO T315 ORIGINAL BINDER PERF. CRITERION: |G*|/sin(δ) >= 1.0000 kPa This sample is found to F A I L at 94.0 °C The test temperature is not according to AASHTO T315!
