This project was a continuation of NCHRP Project 20-68A

The objective of NCHRP Project 20-68A(02) was to plan and manage the execution of domestic technology scans, each addressing a single technical topic. AASHTO and NCHRP identified scan topics, based on suggestions submitted by state DOTs and FHWA. Each scan was planned and conducted with a scan team chair (or co-chairs) and 8 to 10 scan-team members. A subject-matter expert, working with the scan-team chair and members, was responsible for (a) conducting a desk scan; (b) defining the appropriate duration of the scan, its technical structure, and other factors likely to influence planning of the scan; (c) preparing scan technical materials; and (d) supporting the scan-team's reporting of their experience and findings. AASHTO and NCHRP identified scan team chairs and members. The management team was responsible for receiving scan-topic descriptions from NCHRP; planning, executing and documenting scans, including securing NCHRP approvals of interim and final products; and preparing an annual report of the domestic scan program's activities.
