Abstract
State transportation agencies (STAs) implement countless transportation products that are identified, evaluated, and accepted through a Product Evaluation Program (PEP). Through an effective PEP, STAs can ensure the continuous availability of high performance products to be used on various construction and maintenance projects. STAs are encouraged to constantly monitor and update an Approved or Qualified Product List (APL or QPL, respectively). The purpose of this study was to assess the current state of practice of PEPs throughout transportations departments in the United States. The researcher analyzed flowcharts, product application forms, and standard operating procedures, and also conducted an extensive academic literature related to the subject. A survey was then developed and distributed to all 50 DOTs (56% response rate). Follow-up interviews were conducted with about half of the respondents. Data was collected on PEP staffing levels, satisfaction, size of approved product lists, annual budgets, and more.The study found that, in general, PEPs lack priority, consistency, and coordination. Statistical analyses revealed that agencies dedicating equal time toward both phases of evaluation (initial product application review and technical product review) have achieved the highest satisfaction levels for PEP communication and performance. An optimal PEP management model is proposed, and includes a modified product application form, past performance survey (where applicable), and revised product evaluation form.
