Study on the disastrous impact of the flood on pavement of North Bihar, India

Floods are one of the most extreme events that affect human life in different regions worldwide. In India, North Bihar is one of the regions affected by floods every year during the monsoon season. Every year, floods cause the loss of human and cattle lives. It has also become the reason for enormous economic loss. Damage to infrastructure is a significant cause of such economic loss. Every year, transportation infrastructure gets inundated due to damage to the pavement during severe flood conditions. Many researchers have investigated the impact of floods on pavement structures. They have reported the different factors significantly influencing the pavement during flood conditions. Different forms of pavement failure take place due to this. Pavement deterioration models were developed to predict pavement damage. None of the deterioration models are suitable for all regions. The suitability of deterioration models depends upon conditions in the selected region. In this study, the impact of floods on the pavement in North Bihar is investigated. The different forms of pavement failure were identified and their extent was analyzed. Also, a mathematical model was developed to predict different forms of failure due to floods in North Bihar. It was observed that the height of flood has significant impact on the different parameters considered in this study.
