Welcome to the Maryland Product Evaluation List (MPEL) web site. This site provides a repository consisting of findings from the evaluation and testing of new and/or proprietary, engineered transportation products. Registered vendors can submit requests for evaluation of their products by the Maryland Department of Transportation.

The Office of Materials and Technology maintains a listing of Qualified Materials used on Maryland State Highway Administration construction projects. Qualified materials are those which have undergone a prescribed procedure for submittal, testing, and pre-approval. Qualification does not imply that materials can be used on SHA projects without regard for normal Quality Assurance testing and procedures.
The products identified are approved for usage in the State of Maryland as Patented or Proprietary Products under 23 CFR 635.411. Certifications are products certified by MSHA that are either Essential for Synchronization, or that No equally suitable alternative exists. Experimental products are approved by FHWA and are used for research or for a distinctive type of construction on relatively short sections of road for experimental purposes. Public Interest Findings are specific products or materials specified for use when other acceptable products or materials are available, if FHWA approves of its use as being in the public interest.
This document outlines procedures for the consideration and evaluation of new products and processes by MDSHA.
This guide addresses the needs of vendor representatives who want to submit their products for evaluation to MDSHA.
Please contact Maryland SHA via e-mail if you have any comments, questions, suggestions, or concerns about product evaluation or the MPEL web site.
