Yol inşaatlarında dolgu malzemesi olarak kullanılan doğal zemin kaynaklarının giderek azalması, alternatif malzeme ihtiyacı doğurmaktadır. Bu ihtiyaç doğrultusunda büyük miktarlarda yapı malzemesi gerektiren yol inşaatı gibi yapım işlerinde, atık malzemelerin kullanılabilirliği güncel bir araştırma konusu olarak karşımıza çıkmaktadır. Bu çalışmada; geri dönüştürülmüş beton agregası (RCA), geri dönüştürülmüş asfalt agregası (RAP), elektrik ark fırın cürufu (EAF) ve pota cürufu (PF) gibi atık malzemelerin geoteknik uygulamalarda dolgu malzemesi olarak kullanılabilirliği araştırılmaktadır. Bu amaçla temin edilen atık malzemelerin; dane çapı dağılımı, özgül ağırlığı, kompaksiyon özelliklerileri, permeabilite katsayıları, kayma mukavemeti parametreleri, ıslak ve kuru CBR değerlerini belirlemek üzere deneyler yapılmıştır. Bunlara ek olarak, çelik cüruflarının şişme potansiyelleri hızlandırılmış şişme deneyleri ile belirlenmiştir.
