CONCRETE PAVEMENT

The behavior of concrete pavement that is exposed to loading and environmental effect entirely depends upon the quality of concrete, the underlying sub grade, and the base course. Generally, concrete is strong in resisting compression load acting on it, but considerably weak in resisting tensile stresses. Thus, concrete pavement acting as a beam, resting on a weak sub-grade and base courses, is also weak in carrying heavy load associated with impact forces. The reaction and movement of the sub-grade supporting the slab, affects the stability of the concrete pavement.
