The construction, maintenance, and operation of transportation infrastructure requires immense amounts of products and materials. New products, materials, engineered systems, and innovative technologies are presented to state departments of transportation (DOTs) by suppliers and manufacturers, as well as sometimes by contractors and internal DOT staff.

NCHRP Synthesis 616: State DOT Product Evaluation Processes, from TRB's National Cooperative Highway Research Program, documents current state DOT practices, funding, policies, management techniques, tools, and workflows of product evaluation processes.

Supplemental to the report is a dataset of various administrative documents from different state DOTs.
