Specifications Using Recycled Materials by Material

TxDOT has eliminated unnecessary requirements for virgin materials in its construction and maintenance specifications. Additionally, we have approved specifications that specifically call for or allow for the use of recycled materials. Some specifications require their use, while others allow their use if noted in the plans. Please note, this document is provided for information only and is not to be used for bidding or contract purposes.

Specifications Using Recycled Materials can also be viewed by Application. Please contact us if you have any questions.
