Investigations for curling stress in self-Compacting Concrete Pavements

  • Shoib Imtiyaz Dar, Brahmjeet Singh


A road pavement is a construction composed of superposed layers of processed materials over the subgrade natural soil. In India, flexible flooring for road construction is favored because of cheaper building costs and speed of construction as compared to rigid flooring. However, maintenance expenses for rigid floors are considerably cheaper than the maintenance costs for flexible floors. The rigid pavements are built by casting concrete sheets over dry lean concrete or granular substructures. Cement concrete flooring is intended to resist traffic loads and environmental stresses throughout its lifetime. In the concrete pavement analysis, the environmental variables examined include temperature, moisture, precipitation and frost/heavens. The strains produced by daily temperature variations in the concrete paves are known as curling stress. In the concrete pavement analysis, curling stresses are as significant as axle loads, since they are able to cause cement concrete pavements to collapse alone. The stiff floors are built of typically vibrated concrete. Self-compacting concrete (SCC) is favored over regular concrete primarily because of enhanced mechanical characteristics and building speed. The usage of the natural river sand in concrete manufacturing becomes impracticable and outdated due to environmental laws and concerns. Crushed sand is now extensively utilized in concrete production.
