The transportation industry faces a wide range of plausible future drivers and scenarios that could affect standard practices over the next 30 to 50 years. Because the range of plausible futures over such a long-term period is very broad, making a focused prediction of the implications for highway infrastructure preservation, maintenance, and renewal (PMR) is quite challenging.
The TRB National Cooperative Highway Research Program’s NCHRP Report 750: Strategic Issues Facing Transportation, Volume 7: Preservation, Maintenance, and Renewal of Highway Infrastructure focuses on the issues affecting the PMR of highway infrastructure. The study places emphasis on preparing for plausible future scenarios and develops a pathway to guide transportation agencies in advancing the implementation of emerging PMR practices through a process involving awareness, advocacy, assessment, adoption, and action planning.
The appendices to Parts A and B of this report are available as part of NCHRP Web-Only Document 272: Existing and Emerging Highway Infrastructure Preservation, Maintenance, and Renewal Definitions, Practices, and Scenarios.
In addition, there are two guides included within the report that help with the understanding, identification, application, and implementation of emerging PMR practices. They are also available as standalone guides:
