AB  - Bu çalışmada, Etilen Vinil Asetat (EVA) polimer katkısının bitümün fiziksel ve yüksek sıcaklık performansı üzerindeki etkisi incelenmiştir. Araştırma kapsamında geleneksel bitüm deneyleri ile birlikte dönel viskozite deneyleri gerçekleştirilmiş ayrıca bağlayıcıların yüksek sıcaklık performansını belirleyen reolojik çalışmalar dinamik kayma reometresi (DSR) ve çoklu gerilmeli sünme geri dönme (MSCR) deneyleri yardımıyla uygulanmıştır. Çalışmanın sonucunda, EVA polimeri saf bitümün penetrasyonu düşürdüğü, yumuşama noktası ve viskozitesini ise arttırdığı tespit edilmiş bu sayede bitümün fiziksel olarak sertleşmesine neden olduğu ortaya konmuştur. Ayrıca, çalışma kapsamında DSR yüksek sıcaklık performans sınıfı (PG) 76 °C olarak tespit edilen %7 EVA katkılı bağlayıcının MSCR deneyine göre performans sınıfı PG70S olarak belirlenmiş ve PG64S olan saf bitüme göre bir sınıf artış sağlandığı belirlenmiştir. Bu sonuç, EVA katkılı bitümün 70°C sıcaklıkta, 70 km/s üzeri araç hızında ve yirmi yıl boyunca trafik tasarım şeridinde beklenen maksimum 10 milyon (eşdeğer standard dingil yükü) ESAL sayısında kalıcı deformasyona maruz kalmadan kullanılabileceğini ifade etmektedir.

N2  - The effects of Ethylene-Vinyl Acetate (EVA) on physical and high temperature performance of bitumen was investigated in this work. conventional bitumen tests, rotational viscosity tests were conducted within the context of the research, and rheological studies such as dynamic shear rheometer (DSR), multiple stress creep recovery tests (MSCR) were also performed to determine high temperature performance of binders. The results indicated that EVA polymers reduce penetration, increase the softening point and viscosity of the bitumen which in turn indicates bitumen became stiffer after the modification. Besides, %7 EVA modified binder classified as PG 76 in DSR test was graded in MSCR grading system as PG70S which is one level higher compared to that of base bitumen. This result means that EVA modified binders can be used without permanent deformation until 70°C, under 10 million ESAL at 70 km/h traffic speed.
