Dynamic Properties of Hydraulic Mechanically Stabilized Slag as Railroad Material
철도노반재로서 수경성입도조정고로슬래그의 동적 물성특성
Abstract
Dynamic properties of hydraulic mechanically stabilized slag(HMS25) was studied for utilizing it as a roadbed material. HMS25 is a by product material during pig iron production process. It has a very good potential application as a roadbed material. Therefore, the resonant column and torsional shear tests were carried out to evaluate the dynamic properties of HMS25 which are necessary for designing roadbed of railroad track. As a result, it was found that HMS25 has excellent dynamic properties required for roadbed material used in railroad track.
