Macroscopic Performance and Microscopic Characterization of High Viscosity Modified Asphalt
The article compares and analyzes the macroscopic performance and microscopic characteris-tics of three commonly used high-viscosity modified asphalt,including conventional physical properties(pen-etration,softening point,ductility,60 ℃ power viscosity,etc.)and storage stability,and at the same time,the use of fluorescence microscopy,infrared spectrometry,atomic force microscopy and other observations of different high-viscosity modified asphalt microscopic characteristics.The results show that:TPS high-vis-cosity modified asphalt has excellent low-temperature performance,CNTs/SBS high-viscosity modified as-phalt storage stability is the best;from the microscopic test results can also be seen in CNTs/SBS modifier modification effect is the best,the performance is the most stable,a comprehensive point of view of the CNTs/SBS high-viscosity modified asphalt performance is the best.
