Welcome to the AASHTO Product Evaluation List (APEL) web site. This site provides a repository consisting of findings from the evaluation and testing of new, innovative, and/or proprietary engineered transportation products and materials. The three types of information contained within the site are as follows: AASHTO Evaluated Products, State Evaluated Products, and State Certified Products. It is important to note that APEL is NOT an approved products list, rather it is a source for independent, unbiased data and information from which state product coordinators may determine to use new, innovative products in conformance with the Code of Federal Regulations 23 CFR 635.411 (a)(2).
