Waste materials such as waste tire rubber WTR waste cooking oil WCO bio oils waste engine oil WEO and other waste oils have been the subject of various scientific studies in the sustainable and waste research field The current environmental concerns have been identified to protect natural resources and reuse waste materials Accordingly this work
The two asphalt binder were identical in term of asphalt A7 60/80 pen and asphalt A11 100/120 pen and two rejuvenator were identical in term of RA containing 90% alkyl aromatic oil and 10%
ABSTRACT Reclaimed asphalt pavement RAP mixtures reduces environmental burden by utilising existing pavement material However RAP percent is limited due to performance issues at higher RAP content due to improper blending The degree of blending can be improved using rejuvenator Waste cooking oil WCO is gaining attention as a potential
This review highlights that waste cooking oil as a rejuvenator to activate aged asphalt materials is the most promising resource utilization pathway Meanwhile waste cooking oil as a modifier to prepare bio asphalt needs to focus on insufficient high temperature performance Regarding the deficiencies of existing research on the resource
1 Introduction Asphalt Binder provides adhesion in the asphalt mixtures and has a global demand of 143 million metric tons per year Li et al 2022 Although it constitutes 10 11% by volume of mixtures it accounts for 90% of the total cost Asli et al 2012 Dony et al 2013 Mamun and Al Abdul Wahhab 2020 During service life binder undergoes ageing
Recycling of UV aged asphalt has been a hot research issue In this paper waste cooking oil plasticizer toughener and petroleum resin were used as raw materials for asphalt paper explores the effect of regeneration conditions on the regeneration effect of UV aged asphalt binders through high temperature rheology and chemical compositions
Some research projects have studied full recycling of reclaimed asphalt pavement RAP Several additives have been used to rejuvenate the RAP s aged bitumen 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
Waste cooking oil WCO recycled asphalt is facing issues regarding insufficient thermal oxidation stability and aging resistance In this research glycerol esterification was adopted to pretreat WCO and the consequences of this treatment on the aging resistance and thermal stability of WCO were analyzed The impacts of varying levels of esterification of WCO
The two asphalt binder were identical in term of asphalt A7 60/80 pen and asphalt A11 100/120 pen and two rejuvenator were identical in term of RA containing 90% alkyl aromatic oil and 10%
rejuvenators with reclaimed asphalt pavement RAP and/or recycled asphalt shingles RAS to create a high recycled binder Each year it is estimated that contractors receive about 80 million tons of asphalt In addition approximately 11 million tons of waste asphalt shingles are generated of which 10 million tons are from
The purpose of this study was to investigate the regeneration effect of waste cooking oil WCO on aged asphalt with molecular dynamics MD simulation comparing it with a rejuvenator Firstly the molecular models of virgin and aged asphalt were established by blending the four components of asphalt saturate aromatic resin and asphaltenes Then different
The experimental results indicated that WCO qualities influence the rejuvenation behaviors of aged asphalt significantly and the WCO with higher qualities low acid value and viscosity as defined in this research tends to achieve better rejuvenation effects Waste cooking oil WCO in many cases can rejuvenate aged asphalt and restore its properties However
Keywords Reclaimed asphalt RA · Waste cooking oil WCO · Rejuvenation · Blended WCO · Secondary aging 1 Introduction Waste cooking oil WCO is the by product of frying items can also serve as a rejuvenator as indicated by recent studies [15 17] Several studies have also highlighted the impact of the quality of WCO on its
This study examines the merits of esterification of waste cooking oil to reduce its acidic content for use as a rejuvenator for aged asphalt It further examines how acidic compounds in bitumen
With the increasing emphasis on RAP recycling technology in recent years a waste rubber/oil WRO asphalt rejuvenator was self developed by mixing crumb rubber CR with waste cooking oil WCO
AbstractWaste cooking oil WCO was investigated as an asphalt rejuvenator and found to have good potential The properties of the WCO itself will change with usage and the WCO under different stages may affect the bond between the asphalt and minerals
Waste cooking oil WCO is generated when edible vegetable oil is used for frying food items Inappropriate disposal of WCO exacerbates environmental pollution block drains and contaminates terrestrial and aquatic habitats while its consumption deleteriously impacts human and animal health surfactants asphalt rejuvenator are discussed
DOI / Corpus ID 266620878; Biomass waste to produce bio oil as rejuvenator for asphalt based on pyrolysis technology article{Liu2023BiomassWT title={Biomass waste to produce bio oil as rejuvenator for asphalt based on pyrolysis technology} author={Shinan Liu and Houzhi Wang and Jun Yang and Sang Luo and Yixuan Liu and Wei
In parallel the performance of encapsulated new soybean oil and waste cooking oil WCO is compared via their characterization and effects on the mechanical properties of asphalt and J Pei 2015 Design preparation and properties of microcapsules containing rejuvenator for asphalt Constr Build Mater 99 2 143 149 https
In road construction different types of waste oil have been recommended to overcome the stiffening effect of reclaimed asphalt pavement content However the selection of an effective rejuvenator based on a comparative study can lead to using the resources more efficiently In this study waste cooking oil and waste engine oil are used to rejuvenate three
It is also referred to as used cooking oil UCO non edible oil or waste oil WEO A small amount of waste cooking oil is appropriately collected and recycled A large amount of waste cooking oil is deliberately thrown into dumping sites and waterways resulting in pollution Controlling waste cooking oil is a major problem
Bio oils from contaminated biomass and industrial biomass wastes semi biomass such as waste cooking oil WCO waste cooking oil residue WCOR and waste engine oil WEO are also incorporated in the asphalt binder as an extender modifier and rejuvenator Asli et al 2012; Azahar et al 2017; Chen et al 2014b; Ji et al 2017; Maharaj et
Waste cooking oil WCO is the by product of frying items utilising cooking oil that contains processed plant or animal fats High reclaimed asphalt RA renders mixtures more prone to intermediate and low temperature cracking failures In this regard waste cooking oil WCO is gaining attention as rejuvenator to incorporate higher RA in
