The asphalt modifier formed by the miscibility of waste cooking oil and rubber is referred to as WRO. WRO modifiers prepared from waste tire crumb rubber (WTCR) and waste cooking oil (WCO) have the potential for solving the problems of segregation of rubber asphalt and the low recycling rate of waste cooking oil.

 · Zahoor et al. (2020) reviewed the utilization of waste cooking oil (WCO) as a possible organic-based rejuvenator of the asphalt-binder pavements. At present, the …

 · Abstract. The modification of binder with waste cooking oil (WCO) for paving materials indicates the implementation of recycling practice with environmental issues concern, thus improving the proper management of this waste product. This paper presents a critical review of the WCO utilisation as a modifier to enhance binder properties.

 · Dynamic Mechanical Analysis (DMA) has been well established to be important for rubbers and polymers, but it can also be applied to manufacturing of ceramics, such as asphalt design. Figure 1. A piece of asphalt mortar loaded into a bending specimen holder [1]. Asphalt pavement is composed of aggregates, such as different sized rocks and sand ...

 · The waste corn oil and waste soybean oil were also used to rejuvenate the aged asphalt, and their ductility at 15 °C were measured (Ji et al., 2017). The test results …

 · Different kinds of waste material fillers, such as, baghouse fines, filling phosphate waste, recycled lime, Jordanian oil shale fly ash, ceramic waste materials, as well as municipal solid waste incineration ash, and many others have been investigated. It was proved that these types of recycled filler could be used in asphalt mixture and ...

Three types of bio-oils generated from wood waste resources are used in this study: the original bio-oil (OB), de-watered bio-oil (DWB) and polymer modified bio-oil (PMB). OB, DWB and PMB were added into the base asphalt PG 58-28 at 5% and 10% by weight.

 · Asphalt binder has been modified with waste engine oil previously and showed, lower consistency, lower moisture damage resistance at higher dosages, and impaired high-temperature performance. In the current study, three different additives were added to solve these issues associated with waste engine oil-modified bitumen.

 · Bio-oil is employed as an asphalt binder modifier and rejuvenator throughout the world in order to improve the binder performance and to utilize the aged RAP binder with …

The authors previously studied full recycling of RAP rejuvenated with waste cooking oil (WCO). The asphalt concrete (AC) manufactured revealed good mechanical behaviour except for rutting resistance. Therefore, they decided to also include in the asphalt mixtures low density polyethylene (LDPE) from urban waste as a low-cost polymer to improve ...

The inclusion of waste engine oil decreased optimum asphalt content, and reduced rut resistance. Meanwhile, it may also have limited improvements on fatigue resistance of the mixtures. Recommended.

 · Hence, researchers strive to find other alternatives to solve these problems, to enhance the performance and lifespan of flexible pavement. Biomass-based bio-oil, such …

Waste-cooking oil (WCO) has received significant attention regarding rejuvenating aged-asphalt binder (AB) in recent years. Most current studies focused on whether the performance of WCO rejuvenated aged-asphalt binder (WRAB) can meet the requirements without considering the susceptibility to performance change after the reaging process …
