Effects of Water-Coupled Cracks on Life-Cycle Assessment of Concrete Pavement under Moving Load

Life-cycle service time of concrete pavement, strongly governed by the coupling of water and cracks, is known as the inevitable issues of ambient-environmental effects on the fatigue life of concrete pavement. This couple is a key determinant for the long-term durability and maintenance in the current design codes. In this study, three-dimensional nonlinear analysis was conducted by integrating the constitutive laws for concrete and cracked reinforced one, modelling of pore water inside cracks, and the multi-yield surface plasticity for soil foundation to examine the fatigue life under high-cycle moving loads of traffic. The behavioural simulation is discussed with emphasis on the prodigious water pressure in narrow spaces surrounded by a pair of crack planes under the repetitive loading of wheel passages and the drastically shortened fatigue life is focused on in view of the maintenance strategy.
