Abstract
This paper employs isothermal annealing at different temperatures to obtain different microstructures of the same modified bitumen with styrene-butadiene-styrene (SBS) copolymer. The effect of polymer-modified bitumen (PMB) morphology on high-temperature rheological properties is investigated based on the same material. The characteristic wavelength ξ of PMB microstructure was calculated from the fluorescence microscopy images. Dynamic shear rheometer (DSR) measurements and multiple stress creep and recovery (MSCR) tests were performed. The PMB morphology-rheology correlation was discussed within the studied temperature and frequency range. Comparing with a binary droplet-in-matrix microstructure, a homogenous PMB morphology tends to store more energy during shear cycles and reach higher recovery after the loading.
