Effect of Warm Mix Asphalt (WMA) Antistripping Agent on Performance of Waste Engine Oil-Rejuvenated Asphalt Binders and Mixtures

Evaluating the performance of rejuvenated asphalt mixes is crucial for pavement design and construction, as using a rejuvenator not only boosts recycling contributes to positive effects on environment but also increases sensitivity rutting moisture. This study was executed evaluate effect warm mix (WMA) antistripping agent, namely nano-ZycoTherm, moisture-induced damage potential mixtures containing 30% 60% aged (RAP) binder with 12% waste engine oil (WEO). For this purpose, resistance in wet dry conditions examined utilizing loaded wheel tracker. In addition, impacts moisture were evaluated different experiments, such modified Lottman (AASHTO T283), resilient modulus, dynamic creep, aggregate coating tracking tests. Fourier transform infrared (FTIR) spectroscopy thermogravimetric (TG) analysis performed identify functional groups, which would be significant terms damage, assess thermal stability samples, respectively. The results revealed that rejuvenation WEO susceptibility mixtures; however, addition ZycoTherm found enhance WEO-rejuvenated mixtures. Furthermore, indicated exhibited better condition compared conventional HMA However, showed poorer condition. summary, adoption WMA RAP techniques demonstrated satisfactory outcomes susceptibility, also, these are much less expensive implement.
