Authorized Materials Lists (AML)

Authorized Material Lists are specified in Caltrans specifications and are primarily a proactive measure used in conjunction with other acceptance activities as outlined in Department standards and guidance documents. The materials included on these lists are authorized for use on Caltrans construction projects. Use of AMLs alone without other corresponding measures may not assure compliance to state and federal regulations. Actual performance of the material will be the responsibility of the vendor and the user.

For products that meet established AML authorization criteria, please submit your request using the Authorized Material List Submittal Form TL 9502.

For AMLs with authorization criteria that are under development, please submit your request for addition to the respective AML using the New Product Evaluation Submittal Form TL9501.
