PCC Paved Ditch

[sehad]

I'm looking for a design guide on concrete paved ditches or for maintenance of paved ditches. Spacing on contraction joints, redwoods, thickness, load transfers(if needed), max slopes, etc......

I'm in the process of a rehab job on a paved ditch built about 40 to 50 years ago and I'm not familiar with the design so I can't immediately spot specific causes of problems. Any publication would be helpful. Thanks.

No, but stuff runs quick in that thread and I was out most of the day. Can you place it here? Thanks in advance!

Thanks. I have some standard plans from La. I'm more interested in the design of the joint spacing. Design of the location of the weep holes, etc. Like I said, I'm doing a rehab job. Case in point. Rule of thumb is contraction joint spacing 30 times the thickness of the slab max. 4 inch slab = 10 ft max spacing. The spacing is 14' so that contributes to the cracking of the slab.

I need to understand the design so that I can say "this" is the problem and "this" will fix it.

The standards do help though, they are slightly different that some of the ones I have seen here.
