Utility Trench repair
(OP)
One of my clients has asked for a detail that shows trench repair with concrete reinforced with #10 mesh with 6"x6" openings tied into the existing concrete by dowels. Any thoughts or sources on this?

For pavement reinforced with WWF they don't dowel the new into the old. The detail calls for using the same size mesh and cutting a dovetail in the existing base. The patch width is the full width of the traffic lane; in the opposite direction it is the trench width + 1'-6" each side of the trench (W+3' total).
Similar for unreinforced pavement or asphalt pavement except the W+3 is reduced to W+2'.
Patch thickness for concrete pavement is the same thickness as the existing; for asphalt pavement it is 6" of asphalt on 6" of stone.

Here's a link to the two drawings. They're not the best quality but I think you'll be able to make out the important items.
