摘要: This study was conducted to investigate the physical and morphological properties storage stability of polymer modified bitumen’s (PMB) mixed with nanosilica (NS). Polymer bitumen, PG-76 NS were concentration weight at 0, 2, 4 6%. Throughout process, binders regulated 163°C blended using a shear rate 3000 rpm for 1 hour. Microscopic examinations bituminous then carried out scanning electron microscopy (SEM); SEM images show that particles disperse well in binder matrix. The NS’ effect on an additional PMB identified some extent reduced viscosity ductility 2 4% NS, 6% stable increase. Additionally, NS-PMBs softening point increased penetration decreased. Furthermore, binders’ depended mainly content succeeded by binder. As result, are good modifier inhibiting oxidizing reactions bitumen
