Grey Correlation Analysis of Physical Properties and Evaluation Index of Graphene-Oxide-Modified Asphalt

The purpose of this study is to analyze the behavior performance index graphene-oxide-modified asphalt. deviation problem caused by determining graphene oxide content single or several independent properties also investigated. By testing physical asphalt with different admixtures (0%, 0.5%, 1.0%, 1.5%, 2.0% mass) in terms viscosity, penetration, softening point, ductility, rheology, etc., it concluded that addition could improve individual matrix 3% 250%. Moreover, grey correlation analysis method used calculate and between oxide. latter has most significant effect on 135 °C Brookfield viscosity modified calculated based above three indexes, an estimation error less than 0.15% observed. This proves new determination reasonable. Finally, combining macroscopic multi-factor statistical analysis, a reference basis provided for quality control
