TL;DR: In this paper, the effect of waste edible vegetable oil on the rejuvenation of aged asphalt binders was investigated in terms of physical, chemical and rheological properties, and it was shown that waste vegetable oil can effectively soften aged asphalt.

TL;DR: In this article, the use of recycled brick powder as replacement of mineral filler in asphalt mixture was investigated and a comparative study was carried out on the performance of two mixtures using recycled bricks powder and limestone filler.

TL;DR: In this article, the potential of using recycled fine aggregates powder (RFAP) as filler in asphalt mixtures was investigated, and the results indicated that RFAP can improve the properties of asphalt mixture, such as including water sensitivity and fatigue resistance.

TL;DR: In this article, the authors investigated the high temperature rheological properties of rejuvenating aged asphalt binder with rejuvenator, waste cooking and cotton seed oils, and the results indicated that the rutting resistance factor and the complex modulus of rejuvenated binders decreased due to the addition of rejuvenator and waste cooking or waste cooking oil while their phase angles increased.

TL;DR: 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.
