An array of resources exists, ranging from theoretical to application-based documentation and guidance for the evaluation of products for use in state DOTs' construction and maintenance operations.
From page 11...
... Literature Review 11   Traditionally, product evaluation is the responsibility of the state DOT, which develops independent product evaluations requiring various resources and staff levels.

... 18 State DOT Product Evaluation Processes Each product submitted is evaluated based on performance, department priorities and needs, and compliance with all health, safety, and environmental laws and policies. Products that do not perform, do not fill a need, or do not meet safety and environmental requirements are neither accepted nor used in Caltrans's construction and maintenance operations.

... Literature Review 19   2.4.3 Michigan DOT Michigan DOT uses the new materials and qualified products evaluation process. New materials are defined as those that have no current specification or use and are only considered by Michigan DOT when the material is fully developed and commercially available for construction or maintenance activities.
From page 20...
... 20 State DOT Product Evaluation Processes Once the evaluation is complete, the SME decides whether to reject the product with appropriate justification, continue to further study the product, or accept the product. Products that are accepted are then recommended for development as a standard or supplemental specification, a special provision for construction, a standard plan, or a qualified product evaluation procedure.
