Superpave ve Marshall yöntemlerinin deneysel karşılaştırılması

Bu çalışmada, asfalt beton numuneleri Superpave ve Marshall yöntemlerine göre hazırlanmış ve onların tasarım şartnamesine göre karşılaştırılmıştır. Superpave numunelerinin hazırlanmasında Fırat Üniversitesi Bilimsel Araştırma Projeleri Birimi (FÜBAP) desteğinde yaptırılan yoğurmak presten faydalanılmıştır. Her iki yönteme göre hazırlanan numuneler, stabilite, birim ağırlık, boşluk yüzdesi, agregalar arası boşluk yüzdesi ve akma değerleri bakımından karşılaştırılmıştır. Bu karşılaştırma neticesinde her iki yöntemin birbirine göre avantaj ve dezavantajları belirlenmiştir. Superpave numunelerinin optimum asfalt içeriği, Marshall numunelerinden daha az elde edilmiştir.

Experimental comparison of Superpave and Marshall methods

In this study, asphalt concrete specimens were prepared according to The Superpave and Marshall mix design methods, were compared according to their design specifications. Gyratory compactor developed by The Firat University Sciencific Research Project Unit (FUBAP) was used. The specimens prepared according to the stability, specific gravity, percent air void, voids in mineral aggregate and flow. In this comparison, the advantages and disadvantages of both methods were evaluated. Design binder content of Superpave specimens were determined to be less than that of Marshall specimens.
