Modification of Asphalt Modified by Packaging Waste EVA and Graphene Oxide

A composite modifier made from waste ethylene-vinyl acetate copolymer (WEVA) and graphene oxide (GO) is used to modify asphalt pave the roadway. At same time, effect of GO on related properties modified investigated in terms softening point, penetration, ductility, as well distribution. The preparation can reduce modification’s complexity enhance modifier’s dispersion system storage phase. By increasing WEVA contents, point increases, both penetration ductility decrease. It proved that high-temperature performance by better than with WEVA. distribution characteristics a fluorescence microscope show adding more GO, we get even smaller “bee structure” system. indicates promote stop aggregation FTIR spectrum results modification physical modification, indicating physically prevent polymers We present schematic improvement GO. In all, this study provides an idea for application nano-materials.
