“…7 is a plot of the G*/Sin (δ) parameters obtained from the DSR test results. These results are for the 40/50 binder that was then blended with 1%, 3% and 5% and JCO [16,19]. The control binder, shown in blue (40/50) have an upward shift for all data points, and had an overall of PG 76, indicating the binder stiffness.…”

Abstract. Reclaimed asphalt pavement (RAP) usage has increased recently due to the decreasing supply of liquid asphalt and concerns over adverse health effects when making use of petroleum-based/chemical recycling agents which increased the need for bio-based recycling agents designed to return the RAP binder to its original state. The objective of this study is to investigate the possibility of using jatropha curcas oil (JCO), which is a non-edible oil (do not compete with the food chain) that cannot be used for nutritional purposes due to the presence of anti-nutritional factors, such as phorbol esters, as a bio-base rejuvenating agent for aged bitumen. The physical properties and storage stability of the bio-oil, original bitumen, aged bitumen and rejuvenated bitumen were measured. The results of the investigation indicated that the bio-oil have potential to rejuvenate aged bitumen to condition that resembled the original bitumen, the use of the bio-oil show benefits from both health and environmental perspectives. Also the rejuvenated bitumen was found to be very stable in term of storage.

“…1 below is a plot of complex modulus 'G*parameters against phase angle obtained from the DSR test results. These results are for the 40/50 binder that was then blended with 1%, 3% and 5% and JCO for subsequent testing (M. E. Abdullah et al, 2016). The binder blend with 3% JCO, shown in light blue, fails specification at 70ºC, which is expected for a PG 64 or 80/100 binder.…”

“…Materials for asphalt paving and standard structures must be complied with the requirements of standard specified by Highway Department in order to be sure that it's suitable to utilize and last long whilst highly safe for the users. However, HMA shows limitation on temperature, soften when the temperature is high and cracked when the temperature is low causing oxidation of asphalt because of aging process [1][2][3]. In addition, heavy traffic,high loading weight and wet tropical climatic conditions will damage the roads although these pavements are still in service cause large expenses for maintenance due to pavement distress [4].…”

Issue of rubber additive in asphalt mixture has been discussed in asphalt industry Malaysia and its usage was suggested to be used in Pan Borneo Highway project. Using rubber additives can increase revenue rubber tappers in Malaysia. Hence, a study was conducted by the Public Works Department (PWD) and Malaysian Rubber Board (MRB) to investigate the properties of Cup Lumps Modified Asphalt (CMA) based on PWD specifications and its performance. The study area selected was at FT02, Jalan Kuala Lumpur - Kuantan, Temerloh Pahang. In this study, 5 % Cup Lump Modified Binder (CMB) were used. Tests involved were Penetration Softening Point, Flash Point, Dynamic Shear, Marshall, Road Scanner (RS), Falling Weight Deflectometer (FWD), Skid Resistance (Pendulum Test) and Dynamic Creep. The results indicate that CMB with bitumen 60/70 meet the specification. However, it will tend to rut when the temperature exceeds 70°C. For CMA mixture, it shows similar performance with conventional mixture. Meanwhile, at site, the performance for CMA pavement was better in surface condition (94 % good condition in roughness), structural condition (100 % good condition), skid resistance (SRV 63) and dynamic creep (32.01 MPa) compared to conventional pavement AC14. Thus, it can be suggested that the performance of CMA is better than conventional mixture AC14.
