Keywords: Asphalt Recycling, Reclaimed Asphalt Pavement, Rejuvenator, Waste Engine Oil, Waste Vegetable Oil 1. Introduction Due to increased environmental awareness and limited resources, researchers are seeking for new methods and technologies to ensure sustainability, efficiency and less greenhouse gases in asphalt industry.
Cold in-place recycling methods are used to different extents but are often not very suitable for small construction sites. Therefore, a new process was developed using vegetable oil-based rejuvenators to reactivate the old binder of the reclaimed asphalt pavement (RAP) material. Briefly summarised, RAP is produced on-site from the old pavement, then sprayed with water and rejuvenator before ...
Sep 09, 2017· Microencapsulated Sunflower Oil for Rejuvenation and Healing of Asphalt Mixtures ... The mixtures containing sunflower oil as a rejuvenator showed the best performance in self-healing efficiency. However, the healing efficiency of the mix with microcapsules was lower than the mixture with the rejuvenator. ... Laboratory Evaluation of Waste ...
The improved antiaging property of asphalt binders containing two types of antioxidants (tns-(2.4-di-tert-butyl)-phosphite (168) and antioxidant 1010 (1010)) and waste cooking oil (WCO) were investigated using Fourier transform infrared spectroscopy. In addition, the regeneration of WCO in aged asphalt binders was discussed.
Investigation of the possibility of using waste cooking oil as a rejuvenating agent for aged bitumen Majid Zargar, Esmaeil Ahmadinia, Hallizza Asli, Mohamed Rehan Karim Bitumen is a useful and expensive material with high thermal sensitivity. Despite the limited resources, it has been applied in
Therefore, a new process was developed using vegetable oil-based rejuvenators to reactivate the old binder of the reclaimed asphalt pavement (RAP) material. Briefly summarised, RAP is produced on-site from the old pavement, then sprayed with water and rejuvenator before it is mixed thoroughly and immediately compacted.
