The objective of this research is to develop proposed AASHTO guidelines for a data-driven risk assessment at the bridge and structure level. The guidelines considered risks from natural and man-made hazards and aimed to be useful in a bridge management system.

For this NCHRP Project 20-07/Task 120 Asset Management, the consultant assisted the AASHTO Task Force on Transportation Asset Management by coordinating numerous on-going activities and by contributing to the development of the AASHTO Strategic Plan for Asset Management. The consultant coordinated the business of the Task Force with the FHWA, AASHTO members, and other public and private agencies regarding the operation, improvement, and preservation of transportation assets. The consultant helped coordinate and facilitate a workshop on asset management held in Scottsdale, Arizona, on December 1-3, 1999.

The objective of this research, NCHRP Project 14-20A Consequences of Delayed Maintenance of Highway Assets, was to develop processes for quantifying the consequences of the delayed application of maintenance treatments on highway pavements, bridges, and other physical assets. The research expressed consequences in terms of performance indicators (e.g., distress and level of service), costs to owners and road users, and other relevant factors and defined delayed maintenance applications by (1) the inability to meet the agency-defined application schedule or (2) the available budget relative to an unconstrained budget (i.e., availability of the funds required to perform all needed maintenance).
