AASHTO has released a project proposal for the development of AASHTOWare Project Data Analytics. Learn more about this new addition to the AASHTOWare Project Software Series.
Please forward this brief survey to your Maintenance, Construction, or Traffic Safety managers in your agency with responsibility for pavement marking standards and practices. The Utah Department of Transportation (UDOT) is seeking information on your state DOT's experience with the application of Temporary Striping and Permanent Striping during the wintertime. We are seeking to improve the retroreflectivity and durability of striping (primarily paint) that is applied when needed in the winter.
The following questions were asked as part of this survey:
1. Does your state DOT have a Policy or Specification that you would be willing to share that describes your requirements for the application of both Temporary Striping and Permanent Striping during the wintertime? If yes, please provide links or attachments with these Policies or Specifications and a short explanation.
2. What is the contact information for the person in your state DOT with whom we may follow up to learn more?
