An Expert Task Group (ETG) will advise the below describe committee regarding priorities in terms of the technical tools and products that state departments of transportation need to maintain and improve the performance of their pavements. The ETG will not issue a formal report.
The ad hoc committee (TRB-SASP-17-04), which is parent to the ETG and which was approved by GBEC on April 12, 2017, will advise the Federal Highway Administration (FHWA) Infrastructure R&D Program regarding priorities in terms of the technical tools and products that state departments of transportation need to maintain and improve the performance of their pavements, bridges, and other structures. FHWA's program includes gathering data on long-term infrastructure performance; structural design; material testing, evaluation, specification and mixture design, and optimization for both traditional and innovative materials; performance evaluation and prediction; construction; life-cycle cost analysis; environmental and sustainability aspects and implications; preservation of bridges, tunnels, culverts, geotechnical elements; aerodynamic and hydraulic engineering guidance; design and mitigation for extreme events (e.g., seismic, blast, and scour); advanced materials and structural systems; tools for the assessment and condition monitoring of highway structures; and data-driven performance management and preservation tools. The FHWA and its contractors are designing tools and predictive models for highway infrastructure owners to use to maintain and improve their assets; the committee’s role will be to comment on such products as appropriate. The committee will meet annually to interact with FHWA and other stakeholders and issue an annual assessment in the form of a letter report.
