Results of Penetration, softening points, ductility test indicated that thermal-oxidation and ultraviolet radiation aging are two different aging behaviors to binders, regardless modified or not. Changes of physical and rheologcial properties after ultraviolet aging not consist with those after thermal aging, Dynamic Shearing Rheometer (DSR) and Bending Beam Rheomter (BBR) test indices showed that visco-elastic properties of both unmodified and modified binder evidently changed after ultraviolet aging, low temperature performance fallen thusly. Low-temperature bending and indirect tensile tests results revealed that asphalt mixture moisture stability and thermal cracking resistances turn to poor due to ultraviolet aging, and validated the different influences between thermal and ultraviolet aging on performances of binder and asphalt mixture MODIFIED ASPHALT 625.06(063) Perpustakaan Direktorat Bina Teknik Jalan dan Jembatan Direktorat Jenderal Bina Marga - Kementerian Pekerjaan Umum (NPP: 3273244A00000001) 625.06(063) Wan a 0000019205 My Library 625.06(063) Wan a 18533 machine generated
