“…Rutting is one of the most common types of failures in asphalt pavements, which is caused by repeated deformation due to high traffic loads and adverse weather conditions. Previous research found that using GO as an asphalt binder modifier improved the deformation resistance measured by the Superpave rutting parameter (G*/sinδ) and MSCR approach [ 18 , 23 , 24 , 25 ]. Several studies have shown that for modified binders, the G*/sinδ parameter is not very effective in evaluating the rutting behavior [ 26 , 27 ].…”

“…Các nghiên cứu của Adnan và cộng sự [11], Zhu và Zhang [12], Zheng và cộng sự [13] chỉ ra rằng, GO cải thiện tốt các đặc tính cơ lý của nhựa đường như độ kim lún, điểm hóa mềm, độ dẻo, và độ nhớt. Một số đặc tính khác của nhựa đường khi bổ sung GO cũng được cải thiện đáng kể như hiệu suất làm việc ở nhiệt độ cao [14], [15], đặc tính làm việc ở nhiệt độ thấp [16], tăng cường khả năng chống lão hóa của nhựa đường [17]. Trong số các chỉ tiêu đánh giá của nhựa đường, độ kim lún và điểm hóa mềm là hai chỉ tiêu quan trọng nhất để phân loại mác nhựa đường theo độ kim lún [18], nên việc xác định 2 chỉ tiêu này của nhựa đường biến tính GO là rất cần thiết.…”

“…The incorporation of GO into AB, producing a synergistic interaction between the two materials, can lead to significant improvements in their viscoelastic properties, resistance to rutting, 29,30 fatigue, 31,32 and aging. [33][34][35] Specifically, Li et al 29 demonstrated that the addition of GO enhances the anti-rutting performance of 80/100 penetration grade (PG) and styrene-butadiene-styrene (SBS) modified ABs. Their findings also revealed that GO has a more pronounced influence on the viscoelastic properties of SBS-modified ABs, thereby emphasizing its significant impact on enhancing the shear modulus (G*).…”

“…Firstly, current studies on GO-modified ABs often employ high agitation parameters (speed, time, temperature) during the modification process; however, they lack specific assessments of the effect of aging on the production of GO-modified AB. [33][34][35] Aging is a crucial factor influencing the long-term performance of ABs, and its impact on GO-modified binders remains inadequately explored. Secondly, there is a notable absence of temperature-viscosity curves for GO-modified ABs, established according to the instructions of ASTM 2493.…”
