Investigation on Different Properties of Bitumen and Asphalt Mixtures Using Advanced Techniques

<p><span style=color: rgba(23 43 77 1)>Asphalt pavement has been subjected to the alternating and coupling effects of traffic load water light heat ice and snow for a long time. The viscoelastic-plastic properties of bitumen make it susceptible to load changes and humid and hot environments seriously affecting its service life and level of service until losing its essential functions. On the one hand how to use advanced techniques to reveal the material and structural characteristics and performance evolution mechanism of asphalt mixtures under complex service conditions is a critical scientific issue. On the other hand it is crucial to utilize the advanced technology to enhance the resistance ability of bitumen and asphalt mixtures to complex service conditions. This Special Issue aims to use different advanced techniques to characterize and improve the other properties of bitumen and asphalt mixtures at multiple scales including characterization techniques such as microstructure characterization phase analysis composition analysis thermal performance functional application and mechanical performance of traditional or multi-functional asphalt mixtures.</span></p>
