Question for all you Civils out there

Chuck: I dunno, something about calculating all that head in the pipe ....

As long as you have good flow, and seepage is minimized.

I don't see anyone advising you to have an erosion and sediment control plan prepared and certified by a PE or CPESC. Chucktown's specs are useless if they don't call for that - you will find yourself shut down by the CODPH faster than you can say "silt fence" if you don't get your earthmoving permit first, and you cant' get it without the ESC plan and specs.

: ldman: :rtft:

Just put up some silt fence. It's covered in the earthwork spec.

 

[Dleg]

That won't satisfy most permitting authorities. He'll need a certified plan and have it approved beforehand.

actually, with all those diapers you are running thru Mechguy, just take a few of them and sprinkle the filling in the crack. they will absorb any available mosture and expand to fill any void there.

and keep your disturbance under an acre and you can avoid the stormwater permit from CDHPE.

unless you are in texas, then cdhpe won't bother you there either.

 

[Dleg]

You could also settle a permit dispute with a duel, in Texas.

Sounds like you guys have all this geotech stuff figured out. I'll go back to making inane comments and posting photos.

^^^nice

That looks like the right stuff. I would also suggest a sealant for the grout after it cures.
When installing the grout, I would recommend using high-pressure air to clean out the groove as best as you can (especially each face of exisiting concrete). Then moisten both faces of the crack. The moisture will help remove any additional dust and will help the grout to adhere to the existing concrete as well as helping the grout cure properly.

^^All very good advice.

Micropiles! You need them!

This is the best suggestion yet! I may have to rethink my strategy....

Mechguy IS in texas....

Sounds like you need a transportation engineers opinion...I recommend a longitudinal dowel retrofit with polymer coated rebar. a new pcc surface course and obviously high grade silicone filler material...this solution also works well with mudjacking...The real cost question then becomes if you want to use 3000 psi or 5000 psi concrete...obviously due to liability concerns and unknown traffic counts I naturally have to recommend the 5K concrete.

 

[Dexman PE]

I believe the 5000 psi concrete was already recommended by the geotechs...

 

[FLBuff PE]

When did this become a 'pile on the geotechs' thread? Nice to know our work is as well respected in the engineering community as in the rest of the world.

 

[Dexman PE]

We're not piling on anything. The latest geotech report didn't have any piles in it...

I'm just getting tired of my work getting shat on, or being viewed as easy or 'just a checkmark on the form' that needs to be taken care of. Guess who they usually come after first when things go wrong?

Usually the Surveyor!

 

[TranspoVA]

Geotechs always recommend 5000 psi concrete...and oddly enough none of the geotechs brought up soil borings or mechanical stabilization so Im a little disappointed.

If it makes you feel any better FLBuff, I appreciate your inputs I'm probably still going to go with the cheapest, quickest option though LOL
