Abstract (2. Language): 
In this study the use of steel slag obtained from Sivas Divriği Iron-Steel Plant in hot mix asphalt was investigated. For this purpose steel slag was used as filler material considering the grading. Furthermore the effects of binders containing styrene-butadiene-styrene on the mixtures including steel slag were investigated. From the obtained results it was determined that, the mixtures containing Sivas Divriği steel slag showed similar performance in terms of Marshall stability, retained Marshall stability and exhibited better performance in terms of Marshall quotient (MQ), indirect tensile stiffness modulus than the mixtures prepared with limestone. It was also determined that this mixtures did not give satisfactory results with regard to resistance to moisture damage and the polymer modification did not have a significant effect on the performance of hot mix asphalt containing steel slag.

Abstract (Original Language): 
Bu çalışmada Sivas Divriği Demir-Çelik Fabrikası'ndan temin edilen cürufun, bitümlü sıcak karışımlarda kullanılabilirliği araştırılmıştır. Bu amaçla demir cürufu, doğal granülometrisine bağlı olarak 200 numaralı elek üzerinde kalan malzeme ve filler yerine kullanılmıştır. Çalışmada ayrıca stiren-butadien-stiren modifiyeli bitümlerin cüruf içeren bitümlü sıcak karışımlar üzerindeki etkileri de incelenmiştir. Elde edilen sonuçlardan Sivas Divriği Demir-Çelik Fabrikası'ndan temin edilen cüruf içeren numunelerin kalker kullanılan numunelere göre Marshall stabilite, kalıcı Marshall stabilitesi bakımından benzer performans sergilediği, Marshall oranı (MQ), indirekt çekme rijitlik modülü bakımından ise daha iyi performans sergilediği belirlenmiştir. İndirek çekme mukavemeti ve nem hasarına karşı dayanım bakımından kabul edilebilir sonuçlar vermediği ayrıca polimer modifikasyonunun demir cürufu kullanılan bitümlü sıcak karışımların performansı üzerinde fazla bir etkisinin bulunmadığı belirlenmiştir.
