摘要：

The transformation in axle loads of vehicles along with environmental factors requires stiff base layer for concrete pavement and one such stiff layer is dry lean concrete (DLC). The DLC would have variable stiffness as a result of the construction practices. The present study focuses on understanding the influence of DLC stiffness on the tensile stresses in plain cement concrete (PCC) slab using Finite Element (FE) analysis. The PCC slabs are analyzed considering various cases: bonded and un-bonded base with positive and negative temperature differentials. From FE analysis, it is observed that an improved DLC base stiffness has a more pronounced effect on stresses to recede in the PCC slab of bonded concrete pavement with a positive temperature differential. The influence of DLC stiffness was less in the bonded concrete pavement with a negative temperature differential, while marginal in un-bonded concrete pavement with positive and negative temperature differentials.
