The Delaware Department of Transportation (DelDOT) does not maintain an approved/qualified products list for most construction products (other than stormwater items managed by our Stormwater Section). If you would like to have your product/material utilized on a DelDOT project, you must submit your material to a contractor completing work for DelDOT. The general contractor would then submit the product/material to the Materials & Research Section who verifies that the product/material conforms to the appropriate specification requirements for the contract.

To see if your product meets any existing specifications, please check the specifications online at DelDOT's website

If your product does not meet any of the existing specifications and is a new product/material, please contact Mr. Greg Hainsworth.
