• Determination of neutral plane position is the key in the analysis of bi-layer cement concrete slab on Winkler foundation; however, there are no solutions for it when the interface of bi-layer slab is semi-bonded. Based on the Kirchhoff hypotheses, a coefficient c was introduced to characterize the interface condition and the equation of neutral plane was formulated in this paper. The change of position of the neutral plane for the bi-layer semi-bonded slab was investigated. In addition, the ratio of the stress distribution along the depth is derived, which is of great importance in the design of bi-layer cement concrete pavements.
