Marmara denizi dip tarama malzemesinin yol inşaatında yeniden kullanım potansiyeli

Öz

Günümüzde, çeşitli amaçlarla gerçekleştirilen deniz tarama uygulaması sonucunda elde edilen malzemeler artık atık olarak görülmemekte ve farklı alanlarda yeniden kullanım potansiyelleri araştırılmaktadır. Bu çalışmada, denizlerde yürütülen tarama işlemleri sonucunda elde edilen malzemelerin çimento ve kireç katkısı ile iyileştirilerek, mühendislik özelliklerinde ki değişimler incelenmiş ve bu iyileştirme sonucunda dip tarama malzemesinin yol altyapı tabakalarında yeniden kullanım potansiyeli irdelenmiştir. Saf halde bulunan ve hazırlanan karışımlar üzerinde Kıvam limit deneyleri, minyatür kompaksiyon ve serbest basınç deneyleri uygulanmıştır. Serbest basınç deneyi 1,7 ve 28 gün gün kür koşulları için tekrarlanmıştır. Yapılan deneyler sonucunda, eklenen çimento ve kireç oranının artmasıyla numunelerin plastik limitlerinin arttığı ile buna bağlı olarak plastisite indislerinin azaldığı tespit edilmiştir. Tüm oranlardaki çimento ve kireç katkıları ve artan kür süresi, malzemenin serbest basınç dayanımını arttırmıştır. Yapılan çimento ve kireç katkısı ile zemin özelliklerinin iyileştiği ve yol altyapı tabakalarında kullanıma uygun olduğu tespit edilmiştir.
