Temporary Traffic Plates ?

[WLGiii]

We have a duct bank crossing a road at 4 ft. wide. I have been asked to approve the specs for this temporary traffic plate used to protect cable trenches (from city traffic) while the concrete cures. This plate will support traffic of all variations during a week long task at that part of the project. So far local DOT has not approved anything we have submitted.

Where can I find anything related to temporary traffic plates that conform to AASHTO Standard HS-2044 ?

Googling didnt help me much.

So , Ive now figured out HS20-44 are AASHTO loading specs for bridges. Where can I get a copy of AASHTO HB-12 - Standard Specs. For Highways and Bridges ?

you can purchase it off the AASHTO website. But, it's not cheap... Maybe you can borrow a copy from a local structural firm.
