摘要: Due to the special characteristics of nanomaterials, nanoclay was selected in this chapter modify base asphalt binder materials. The nonmodified (NMN) and polymer-modified (PMN) were used chapter, original properties tested through field emission scanning electron microscope (FE-SEM) Fourier transform infrared spectroscopy (FTIR). modified binders prepared mixed high shear machine, Superpave™ tests conducted evaluate performance, such as rotational viscosity (RV), dynamic rheometer (DSR), bending beam (BBR). SEM FTIR employed observe microstructures control understand chemical bond ratio changes binders. Based on test results, it is concluded that addition into can improve resistance rutting fatigue cracking well anti-oxidation performance.
