dc.description.abstract
The relaxation spectrum is a critical tool for characterising the viscoelastic properties of bitumen. This study investigates the challenges associated with generating an isothermal relaxation spectrum from frequency domain data spanning a short range of frequencies. Experiments were carried out on unmodified VG30 bitumen at 0 °C and 60 °C across a limited frequency range spanning 1.39 decades. This was extended using generalised linear viscoelastic models with an appropriate number of relaxation modes to derive continuous relaxation spectra. The range of the relaxation time is found to be more for 0 °C than for 60 °C and in both the cases, the corresponding frequency range to capture the dominant relaxation modes was found to be too high to be accessed by the testing equipment.
