In recent years, nanomaterials in bitumen modification have become widespread due to their superior properties. Graphene and its derivatives are prominent examples of this. Therefore, this review study was conducted to evaluate the effect of graphene on bitumen in detail. Accordingly, by examining the literature studies, general information about graphene and its derivatives was given, and the preparation conditions of graphene-modified bitumen were evaluated. Then, the effect of graphene on the physical and rheological properties of bitumen was investigated. In addition, the effect of graphene modification on the performance of asphalt mixtures and the use of graphene in composite modification was investigated. As a result, it was determined that graphene improves the high-temperature performance of bitumen, but its effect on the lowtemperature and fatigue performance of bitumen is mostly negligible. In addition, it has been determined that graphene increases the rutting resistance of bituminous mixtures and positively affects the cracking resistance of bituminous mixtures in general.
Son yıllarda bitüm modifikasyonunda üstün özelliklerinden dolayı nano malzemelerin kullanımı yaygınlaşmıştır. Grafen ve türevleri bunun belirgin örneklerindendir. Bu nedenle, grafenin bitüm üzerindeki etkisini detaylı bir şekilde değerlendirmek için bu derleme çalışması yapılmıştır. Bu doğrultuda, literatürdeki çalışmalar incelenerek ilk olarak grafen ve türevleri hakkında genel bilgiler verilmiş ve grafen modifiyeli bitümlerin hazırlanma koşulları değerlendirilmiştir. Ardından, grafenin bitümün fiziksel ve reolojik özellikleri üzerindeki etkisi incelenmiştir.Buna ilaveten, grafen modifikasyonun asfalt karışımların performansı üzerindeki etkisi ve kompozit modifikasyonda grafen kullanımı araştırılmıştır. Sonuç olarak, grafenin bitümün yüksek sıcaklık performansını geliştirdiği ancak bitümün düşük sıcaklık ve yorulma performansı üzerindeki etkisinin çoğunlukla ihmal edilebilir düzeyde olduğu belirlenmiştir. Ayrıca, grafenin bitümlü karışımların tekerlek izi direncini geliştirdiği ve bitümlü karışımların çatlama direnci üzerinde genel olarak olumlu bir etki gösterdiği belirlenmiştir.
