Numerical Analysis of the Drainage Performance of Steel Slags Used In Embankment Fills

Öz

In this study, the effect of hydraulic conductivity of steel slag, a by-product of steel industry, on the drainage time and the thickness of the highway foundation layer was investigated via DRIP (Drainage Requirement in Pavements) software developed by Federal Highway Administration (FHWA). Three electric arc furnace (EAF) and one ladle slag (LS) from four different facilities along with a control soil were used in the analyses to compare their drainage performance as an embankment material. Analyzes were performed on steel slag and natural aggregate materials to investigate the effect of drainage percentage (U), base layer thickness (H) and hydraulic conductivity (k) on drainage time. The results show that the fines content and hydraulic conductivity significantly affect the drainage time, especially after 40% of the drainage. In addition, increasing the thickness of the foundation causes a serious reduction in the drainage time. When the performances of the control material and the steel slag obtained from different facilities were compared, it was seen that the drainage properties of especially the electric arc furnace steel slag materials yielded satisfactory results in case used as an embankment fill material

ÇELİK CÜRUFLARININ YOL DOLGU MALZEMESİ OLARAK KULLANIMINDA DRENAJ PERFORMANSININ SAYISAL ANALİZİ

Öz

Bu çalışmada, Amerikan Karayolları Müdürlüğü FHWA (Federal Highway Administration) tarafından geliştirilmiş bir yazılım olan DRIP (Drenage Requirement in Pavements) aracılığıyla, demir çelik endüstrisi atık malzemesi olarak ortaya çıkan çelik cüruflarının hidrolik iletkenliğinin drenaj süresi ve karayolu temel tabakasının kalınlığı üzerindeki etkisi incelenmiştir. Analizlerde üçü elektrik ark fırını (EAF), bir tanesi pota fırını (PF) cürufu olmak üzere dört farklı tesisten elde edilmiş çelik cürufu (SS), ayrıca drenaj performansının karşılaştırması ve kontrol amacıyla bir adet tabii zemin malzemesi kullanılmıştır. Drenaj yüzdesi (U), temel tabakası kalınlığı (H) ve hidrolik iletkenlik (k)’in drenaj süresi üzerindeki etkisi incelenmiş olup analizler sonucunda ince dane içeriğinin ve hidrolik iletkenliğin, özellikle drenaj süresini, drenajın %40’ı tamamlandıktan sonra önemli ölçüde etkilediği görülmüştür. Ayrıca, temel kalınlığının arttırılması, drenaj süresinde ciddi bir azalmaya neden olmaktadır. Kontrol malzemesi ile farklı tesislerden elde edilmiş çelik cürufu malzemesinin performansları karşılaştırıldığında, özellikle elektrik ark fırını çelik cürufu malzemelerinin drenaj özelliklerinin yol dolgusu malzemesi olarak kullanımında tatmin edici sonuçlar verdiği gözlemlenmiştir.
