Transportation asset management (TAM) is an area of great importance to state departments of transportation (DOTs) throughout the United States. As defined in Moving Ahead for Progress in the 21st Century (MAP-21), TAM is a “strategic and systematic process of operating, maintaining, and improving physical assets… that will achieve and sustain a desired state of good repair over the life cycle of the assets at minimum practicable cost.” Because of the federal requirements in MAP-21 and subsequent legislation, the interest in TAM has intensified as state DOTs must meet the federal requirements and implement TAM within their agencies as a good business practice.
Numerous NCHRP research reports provide guidance and tools to state DOTs to aid them in implementing TAM in their agencies. Some NCHRP research has been published by AASHTO, including the AASHTO Transportation Asset Management Guide: A Focus on Implementation, 2nd Edition (the Guide). The Guide is available through the AASHTO Bookstore at https://store.transportation.org/Item/CollectionDetail?ID=217) and a digital version available on the AASHTO TAM Portal at https://www.tam-portal.com. Practitioners have suggested that the Guide would be more helpful and more easily implemented if it contained more up-to-date information gained through new research with content updates to the digital guide only, such as new/updated case studies, user checklists, how-to guides, etc.
The objective of this research is to develop new and updated digital content for the online version of the AASHTO Transportation Asset Management Guide: A Focus on Implementation, 2nd Edition (found at https://www.tamguide.com). Updates and new content shall:
  1. Reflect relevant, new research results;
  2. Reflect lessons learned from asset management practices used by other transportation modes;
  3. Describe asset management tools used by state DOTs;
  4. Identify gaps in practice that additional tools may address;
  5. Address pressing issues facing asset management practitioners and decision-makers, including but not limited to equity, climate change, risk and resiliency, making multi-objective decisions, implementation challenges, coordination with regional and local agencies, and emerging technologies;
  6. Add additional practice examples, e.g., how-to guides, checklists, work-flows, standard operating procedure examples, templates, or videos; and
  7. Provide enhancements to the Transportation Asset Management Gap Analysis Tool (found at https://www.tpm-portal.com/tool/tam-gap-analysis-tool-nchrp-08-90/) as well as new or other enhanced asset management tools.
