 note = {Most decision makers face problem in the management of concrete infrastructure like bridge due to existence of uncertainties. Uncertainties may change the physical and mechanical properties of concrete deviates from designed value due to workmanship error, environmental conditions and by others. Deteriorated concrete structures due to uncertain parameters need maintenance and rehabilitation that causes huge financial involvement of the owner. Usually least cost option from life cycle analysis is taken as a measure for repair and rehabilitation. But most critical issue is to predict the actual performance condition of the structure at the study time. Durability parameters are to be considered as probabilistic distribution to take the effect of uncertainties caused by errors mentioned above. In this framework, for the prediction of deterioration, cover depth, permeability of cover and degree of saturation of cover concrete are taken as parameters with log-normal distributions and the probability of failures for each is compared along with the life time. It is found that the concrete with smaller cover-low permeability and high permeability-larger cover have almost similar effects on the service life of structure. It reveals that emphasis should be given on permeability to predict the service life of concrete infrastructure. Life cycle computation was done based on some assumption. 5 types of repair includes in the LCC calculation. Comparison is shown among different repair methods to help the owner to choose best option of repairing method. And effect of cover properties on LCC is also realized in this study.},
