Investigation on Rheological Properties and Microscopic Mechanisms of Sasobit/Buton Rock Asphalt Modified Asphalt

Abstract: The objective of this study is to develop a modified asphalt with excellent rheology and workability. Buton rock asphalt (BRA) composite modified warm mix asphalt (BCMWMA) was prepared, and its rheological properties and micromechanisms were investigated. Initially, warm mix asphalt (WMA) was prepared using 3 wt% Sasobit, and then four BCMWMA samples were prepared by blending 5 wt% to 20 wt% of BRA (with 5 wt% intervals). Subsequently, the microscopic morphology and modification mechanism of BCMWMA were analys… Show more

“…Typical kinds of rock asphalt conclude three varieties, i.e., the Qingchuan (QC) rock asphalt from Sichuan, China, the Uintaite Modifier (UM) rock asphalt from Kermanshah, Iran, and the Buton rock asphalt from Buton, Indonesia [2]. Due to rock asphalt having great compatibility with asphalt binder, it is commonly chosen as a modifier of asphalt binder [3][4][5][6][7].…”
