“…Styrene-butadiene-styrene block copolymer (SBS), one of the most productive thermoplastic elastomers (TPE), has been used in various domains, such as pressure-sensitive adhesives [1,2], footwear, asphalt modifiers [3][4][5][6] and coating because of its good balance between mechanical properties and favorable processability. But the high inflammability of SBS imposes restriction on its application in some high-end fields.…”

The effects of fullerene (C 60 ) and aluminum hydroxide (ATH)/C 60 combination on the thermal stability, flame retardancy and mechanical properties of styrenebutadiene-styrene block copolymer (SBS) were investigated. Adding small amount (0.5-2 mass%) of C 60 into SBS matrix raised the initial decomposition temperature of the composites slightly, while C 60 alone had little influence on the flame-retardant behavior. In SBS/ATH/C 60 system, however, the addition of C 60 significantly improved the UL-94 vertical combustion grade and limiting oxygen index. The total content of the flame retardant in SBS/ ATH/C 60 system (56 mass%) was lower than that in SBS/ ATH system (60 mass%) when UL-94 reached V0 level. Consequently, the adverse effects on the mechanical properties due to the high level of flame-retardant loading reduced. Meanwhile, the data obtained from cone calorimetric test indicated that C 60 can not only reduce the heat release rate, but also raise the char residue of SBS/ATH composites.

Rejuvenator diffusing into aged bitumen was evaluated by determining penetration and chemical components of aged bitumen with rejuvenator coat before and after diffusing experiment. Effects of temperature, time and viscosity of rejuvenator on the diffusing ability of rejuvenator into aged bitumen were investigated. Results indicated that the diffusing ability of rejuvenator into aged bitumen could be enhanced with the increasing of temperature and time, however, the diffusing of rejuvenator into aged bitumen would be restricted due to the volatilization of light component and aging of rejuvenator under high temperature (over 170 ). R ℃ ejuvenator with low viscosity diffused into aged bitumen more easily.

“…This binder needed 3% -4% of WCO to meet the properties comparable with the original 80/100 bitumen. Meanwhile, the penetration value of aged sample from a motorway with 6.3 dmm, need about 20% of WEO to satisfactory to target grade 60/70 bitumen [5]. Zamhari et al [22] revealed that the addition of 10% WEO to the artificial aged bitumen with penetration value 31 dmm have facilitated to achieve the target penetration grade 80/100.…”

“…While a higher RAP content can significantly increase the mixture's stiffness. Through rejuvenation, the properties of the old asphalt pavement (particularly its binder properties) can be improved to restore the original ratio of asphaltenes to maltenes and compensate the hardening effect [3][4][5]. Asphaltenes is a solid, hard, brittle component that is not affected by oxidation, whereas maltenes is liquid, oily and resinous in appearance [6].…”

Road construction necessitates a high amount of bitumen, which is a non-renewable material. The usage of reclaimed asphalt pavement (RAP) can be seen as a sustainable option, which offers economic benefits and conservation of natural resources. However, the high stiffness offered by RAP which leads to cracking has impelled the application of rejuvenator. The exploration of waste oil as the rejuvenator has gained the interest but they still lack of the information. This paper aims to highlight previous research works conducted on the waste oil application in the pavement materials. Large amount of waste product from the automotive industry and by-product of frying can impose adverse impact if not disposed properly. The properties of two types of waste oil namely waste engine oil (WEO) and waste cooking oil (WCO) were reviewed. Additionally, method incorporating waste oil in pavement materials, effects to the binder and mixture performance also included. It was observed that the effects of WEO and WCO are commonly produced both of the adverse and good effects to the pavement. The temperature, amount of waste oil and RAP are notable to give significant influence on the performance properties.
