Özet
Öz: Bu çalışmada, çelik üretimi esnasında bir yan ürün olarak ortaya çıkan Yüksek Fırın Cürufu (YFC) ile stabilize edilmiş killi bir yol taban zemininin yol esnek üstyapı kalınlığına ve maliyetine etkileri araştırılmıştır. Bu amaçla, kil zemine ağırlıkça %5, 10, 15, 20 oranlarında YFC ilave edilerek stabilize karışım numuneleri hazırlanmıştır. Hazırlanmış olan saf ve katkılı numuneler Standart Proktor, serbest basınç ve Kaliforniya Taşıma Oranı (CBR) deneylerine tabi tutularak en yüksek dayanımı veren YFC oranı belirlenmiştir. Bu oran dikkate alınarak, AASHTO 1993 yöntemi ile YFC katkılı zemin üzerine inşa edilecek yol esnek üstyapı tabaka kalınlıkları ve maliyetleri hesaplanmıştır. Deneyler neticesinde, YFC katkısı ile kil zeminin dayanımında önemli iyileşmeler olduğu ve en iyi dayanımın %20 YFC içeren karışımlardan elde edildiği tespit edilmiştir. AASHTO 1993 yöntemi ile yapılan hesaplamalar sonucunda, %20 YFC içeren zeminler için belirlenen tabaka kalınlıklarının, saf killi zemine göre oldukça azaldığı görülmüştür. Her iki zemin için belirlenen tabaka kalınlıklarına göre yapılan tasarım hesabında, zemine %20 YFC ilave edilmesinin, saf killi zemine kıyasla yol üstyapı tabaka kalınlığı %26,67 oranında azalttığı tespit edilmiştir.
Öz: In this study, the effects of a clay road subgrade stabilized by Blast Furnace Slag (BFS), which appeared as a byproduct during steel production, on road flexible pavement thickness and cost were investigated. For this purpose, stabilized mixture samples were prepared by adding %5, 10, 15, 20 BFS to the clay soil by weight. The pure and additive samples were conducted Standard Proctor, Unconfined Compression and California Bearing Ratio (CBR) experiments and the BFS ratio was determined to provide the highest strength. Taking into account this ratio, the road flexible pavement layer thicknesses and costs to be built on BFS-additive soil were calculated with the AASHTO 1993 method. As a result of the experiments, it was determined that there were significant improvements in the strength of the clay soil with the contribution of BFS and that the best strength was obtained from mixtures containing %20 BFS. As a result of calculations made by AASHTO 1993, it was observed that the layer thickness determined for soils containing %20 BFS decreased considerably compared to pure clay soils. In the design calculation according to the layer thicknesses determined for both soils, it was determined that adding 20% BFS to the soil reduced the layer thickness of the road pavements by 26.67% compared to pure clay soil.
