Current legislation and subsequent asset management rules require state departments of transportation (DOTs) to conduct statewide evaluations of roads, highways, and bridges that have required repair and reconstruction activities two or more times since 1997 due to emergency events as declared by the president of the United States or by a state’s governor.

The TRB National Cooperative Highway Research Program's NCHRP Synthesis 556: Asset Management Approaches to Identifying and Evaluating Assets Damaged Due to Emergency Events furnishes documentary evidence of the approaches that state DOTs have taken to identify and evaluate locations where highway assets have been repeatedly damaged and to identify considerations that have been made for mitigating the risk of recurring damage to assets in those areas.

The report is intended to help transportation agencies with building data sets and tools that support the evaluation of damage to assets associated with emergency events and to illustrate methodologies that are being used to integrate these risks into asset investment decisions.
