AASHTO DPA-1-CD

The Design Policy Archive CD-ROM is a new single user Windows CD that contains the AASHTO archived design policy documents listed below. All of the technical information in each has been superseded by new AASHTO policy publications. Historians, attorneys, and law libraries will find this publication to be especially useful, as it brings together in one place all the significant archived AASHTO design policies.
