The Nashville Department of Transportation and Multimodal Infrastructure (NDOT) has formed the Approved Materials Committee to maintain a robust and up-to-date list of approved materials that meet the highest standards. The Approved Materials Committee plays a vital role in assessing and approving materials, products, and engineered systems proposed for use within NDOT.
The committee will convene quarterly to assess applications collected during specified open application periods. The Approved Materials List will be updated based on the committee’s recommendations. Materials that do not meet our standards will not be considered.
The Approved Materials Committee will close its first application window on Friday, April 19. As we strive to enhance safety, reliability, and quality across Davidson County, we welcome your participation.
