Asfalt, sıcaklığa bağlı akış davranışı nedeniyle kendi kendini iyileştiren bir malzeme olarak bilinir. Asfalt betonunda hasar oluştuğunda, bitüm ısı ile çatlaklara akabilir ve çatlakları doldurarak iyileşme sağlayabilir. Kendi kendini iyileştirme ile ilgili mevcut literatürde çoğunlukla, çeşitli yöntemlerle asfalt betonunun yapay olarak ısıtılmasına önem verilmektedir ve mikrodalga ısıtması bu yöntemlerden biridir. Literatürde, mikrodalgayla iyileşen asfaltta çelik liflerinin kullanımını kabul eden çalışmalarda bir artış olmasına rağmen, mikrodalga iyileştirmeyi artırmak için alüminyum liflerin kullanımına ilişkin veri yoktur. Bu makale, alüminyum ve çelik talaşı gibi metal atıklarını içeren asfalt betonunun mikrodalgayla iyileşme potansiyelini değerlendirmektedir. Ayrıca asfalt betonunda bazalt ve kalker agregası (BA ve KA) kullanımı değerlendirilmiştir. Bu amaçla, öncelikle BA ve KA'nın mikrodalga emiş kabiliyetleri belirlendi. Çalışmanın ikinci aşamasında poroz asfalt betonu numuneleri hazırlanmış ve düşük sıcaklıklarda endirekt çekme (IDT) dayanım testi ile hasar verilmiştir. Bundan sonra, hasarlı numuneler mikrodalga ısıtması ile iyileştirildi ve IDT dayanım testi ile tekrar hasar verildi. Sonunda, numunelerin iyileştirme indeksi, iyileştirilmiş numunenin dayanımının ilk haline oranı olarak belirlendi. Sonuçta, BA'nın KA'dan neredeyse üç kat daha fazla mikrodalga emici malzeme olduğu ve BA içeren asfalt numunelerinin daha iyi iyileşme performansı gösterdiği bulunmuştur. Ayrıca, mikrodalga iyileşmesini hızlandırmak için alüminyum talaşlarının çelik talaştan daha iyi bir seçenek olabileceği de ilk defa bu çalışmada ortaya konmuştur.

Self-Healing Potential of Porous Asphalt Concrete Containing Different Aggregates and Metal Wastes Through Microwave Heating

Öz

Asphalt is known as a self-healing material due to its temperature-related flow behavior. When damage occurs in asphalt concrete, bitumen can flow into cracks with heat and provide recovering by filling the cracks. Much of the current literature on self-healing pays particular attention to artificially heat asphalt concrete by several methods, including microwave heating. Although there is a growing body of literature that recognizes using steel fibers in microwave healing asphalt, there are no data on the use of aluminum fibers to improve microwave healing. This paper evaluates the microwave healing potential of asphalt concrete that contains metal wastes such as aluminum and steel shavings. Besides, the use of basalt and limestone aggregate (BA and LA) in asphalt concrete were evaluated. To achieve this, firstly, microwave absorption capabilities of BA and LA were determined. In the second step of the study, porous asphalt concrete specimens were prepared, and they were damaged by the indirect tensile (IDT) strength test at low temperatures. After that, damaged specimens were healed via microwave heating, and they were damaged again by the IDT strength test. In the end, the healing index of the specimens was determined as the proportion of healed specimen’s strength to the original. It has been found that BA is almost three times more microwave absorber material than LA, and asphalt specimens containing BA showed better healing performance. It has also been demonstrated for the first time that aluminum shavings might be a better option than steel shavings to accelerate microwave healing.
