Specialty Products Evaluation

Please send all forms and literature to the Specialty Products Evaluation Coordinator, Kasey Browning, at kasey.browning@la.gov. 

For additional information on the evaluation process, manufacturer responsibilities, and committee responsibilities, please refer to the link above, titled SPE Evaluation Policy.

The Specialty Products Evaluation process was developed to review materials for which LADOTD does not have a current specification or an Approved Materials List. The Specialty Product Evaluation (SPE) Committee, established by DOTD EDSM V.4.1.1, provides for the structured review, evaluation, and implementation of all specialty products and associated procedures submitted to the department. The SPE Coordinator thoroughly documents all submittals, evaluations, and implementation of specialty products.


The committee establishes policies and procedures to give structure and consistency to reviewing, evaluating, and implementing committee recommendations. Chairing the SPE Committee is the Materials Engineer Administrator who appoints members of their staff to coordinate the committee's activities. The committee is composed of the following various sections and divisions of the department:

·         Materials and Testing, Chair

·         Materials and Testing, Coordinator

·         Warehousing and Procurement Section

·         Bridge Design Section

·         Contract Services Section

·         Plan Quality and Publications Section

·         Construction Division

·         Louisiana Transportation Research Center

·         Maintenance Division

·         Materials and Testing Section, Committee Chair

·         Purchasing Section

·         Traffic Engineering Section

·         Traffic Services Section

·         Road Design Section

·         Pavement and Geotechnical Section

Manufacturer Responsibilities: 

A manufacturer requesting a product evaluation by the department must complete a Specialty Products Evaluation Form available from the Materials and Testing Section. The form must be filled out completely and signed by a manufacturer representative who officially authorizes the evaluation of the product and acknowledges the "General Notes" on the form. Additionally, the manufacturer must submit the form and all product literature, MSDS sheets, prior test data, etc., via email to the Specialty Products Evaluation Coordinator. After the SPE Committee meeting, the manufacturer is notified whether the product will be evaluated. The name of the evaluator will also be provided if applicable. ​After completion of the evaluation, the manufacturer will be notified of the committee's actions.

Committee Procedures:

The committee reviews all specialty product submittals and decides whether products merit the department's pursuit of the evaluation. Should the committee decide to evaluate the product, the assigned evaluator may contact the manufacturer and/or representative to set up a time for the manufacturer and/or representative to present to interested parties within the department. One of the department's sections will coordinate the evaluation through the department or APEL/NTPEP. Upon completion of the evaluation, the committee reviews the evaluation results and approves or rejects the product. When a product is approved, the manufacturer shall coordinate the implementation of the product on LADOTD projects.
