A Study on Load Transfer Efficiency of Skewed Transverse Joint of Concrete Pavement by the Fatigue Test

피로실험에 의한 콘크리트 포장체 경사가로줄눈부의 하중전달율에 관한 연구

This paper presents load transfer efficiency of skewed transverse joint of jointed concrete pavement with the fatigue model test. A 1/12 scale model was used to satisfy the geometry, loading, material similitude, which are variables to the skew angel of transverse joint. As the test results by fatigue load 700kgf applied, the deflection and stress of transverse joint were decreased as to increasing of skew angle of transverse joint. In addition, load transfer efficiency of transverse joint with skew angle is better than the load transfer efficiency of transverse joint without skew angle.
