Research the Microstructure and Properties of Modified Asphalt from Dry SBS-T
Keyword(s):
This paper uses a fluorescence microscope to study the microstructure of dry modified asphalt, and compares and analyzes the micro and macro performance of dry and wet modified asphalt. The results show that: in terms of micro performance, when the modifier content is 6%, the dry modifier (SBS-T) becomes to a compact network structure in the asphalt when the shear time is 5 minutes, and it takes 45 min for the modifier to achieve the same result to the wet method. And the macro performance indicators of penetration, softening point, ductility, and viscosity show that the modification effect of asphalt is better by dry modifier is 5 minutes after shearing than the modification effect of asphalt by wet modifier is 45 minutes.
