  • serves as an extensive pavement reference that users can browse to look up typical design values, methods, practices and resources
  • provides approved policies and procedures for pavement design for use on TxDOT projects
  • provides pavement engineers with a uniform, streamlined process for designing pavements
  • includes a list of available training courses for pavement engineers and links to web-based training for pavement design and analysis programs used by TxDOT
  • serves as a guide to pavement engineers for selecting pavement rehabilitation strategies
  • addresses related topics that a pavement engineer needs such as procedures for changing load zones, superheavy load analysis and pavement forensics.
