The modification of bitumen with waste oils encourages the transition5 to sustainable production and consumption strategies by increasing resource efficiency and reducing environmental impacts. In this study, bitumen was modified with waste engine oil (WEO) and waste industrial oil (WIO) at the rate of 2%, 2.5%, 3%, 3.5%, and 4% by weight to increase resource efficiency and contribute to sustainable transportation. Physical tests (penetration, softening point, penetration index, rotational viscometer) were applied to the oil modified bitumens, and the chemical composition of the bitumen as a result of the modification was examined using FTIR, SEM, and EDS analyses. Results indicate that modified bitumens exhibit superior performance in cold climate regions. The modification of 4% WIO and WEO into bitumen reduced the mixing temperature by 3.5% and 5%, respectively, and the compaction temperature by 5% and 10%, respectively. The findings of the study indicate that WIO and WEO can be used in bitumen modification to improve its performance. This study contributes to sustainable production practices by not only utilizing waste materials in a sustainable manner but also reducing the environmental impacts of industrial processes.

ATIK MOTOR VE ENDÜSTRİYEL YAĞLAR İLE MODİFİYE EDİLMİŞ BİTÜMÜN FİZİKSEL VE KİMYASAL ÖZELLİKLERİNİN İNCELENMESİ

Öz

Bitümün atık yağlar ile modifikasyonu, kaynak verimliliğini artırarak ve çevresel etkileri azaltarak sürdürülebilir üretim ve tüketim modellerine geçişi teşvik etmektedir. Bu çalışmada, kaynak verimliliğini arttırmak ve sürdürülebilir ulaşıma katkı sağlamak amacıyla bitüm ağırlıkça %2, %2.5, %3, %3.5 ve %4 oranlarında atık motor yağı (AMY) ve atık endüstriyel yağ (AEY) ile modifiye edilmiştir. Modifiye edilen bitümlere fiziksel deneyler (penetrasyon, yumuşama noktası, penetrasyon indeksi, dönel viskozimetre) uygulanmış ve modifiye bitümlerin kimyasal içeriği FTIR, SEM ve EDS analizleri ile incelenmiştir. Çalışma sonucunda, modifiye edilen bitümlerin hava sıcaklığının düşük olduğu bölgelerde kullanımının daha uygun olacağı tespit edilmiştir. AEY ve AMY ile %4 oranında modifiye edilen bitümlerin karıştırma sıcaklığı sırasıyla %3.5 ve %5 oranında azalırken, sıkıştırma sıcaklığı ise %5 ve %10 oranında azalmıştır. Çalışmadan elde edilen sonuçlara göre AEY ve AMY’lerin bitüm performansını arttırmak amacıyla bitüm modifikasyonunda kullanılabileceği gösterilmiştir. Bu çalışma, atık malzemelerin sürdürülebilir bir şekilde kullanılmasının yanı sıra endüstriyel süreçlerin çevresel etkilerini azaltarak sürdürülebilir üretim uygulamalarına katkıda bulunmaktadır.
