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.
