Bridge repair

[1bush2hog]

There are much better ways to treat the wood vs using hazardous waste.

Copepr napthenate would be my choice for a post dip... That or asphalt based paint that cures to nearly environmentally inert status..

I agree, however, when I was a kid I doubt ANY of that stuff was around. Even if it was we were not aware of it. Aslo, there is more education about environmental issues now than then. Heck where I grew up the State DOT was putting used motor oil on dirt roads to keep the dust down.

I also cautioned about the environmental concerns, maybe I was a little too subtle

Don't invite Senator Kennedy over for your retirement party!

This might be the answer invite Kennedy over and tell him to bring along Ms Plosie. If history repeats might not get a new bridge but you could sure have a nice tourist attraction.

With that said our local engineering collage does some design projects for the student I am told maybe you could get some good Free engineering done this way.

I know lots of places put down dust control oil... but used motor oil.. I wonder how long it has really been since UMO has really been put down.

Dust control oil has been out for quite along time... and the average populess has a hard time discerning between construction materials. Virtually every paving job we go to.. some resident calls the DEP on us and says we have a truck leaking oil onthe ground.. the dep gets out there all in a hurry only to find out that it is asphaltic emulsion dripping from our prime / tack truck... then he shrugs.. and gets bck in his car and goes home...

We're talking appx. 40 years ago and I know what burnt motor oil is

I wasn't singling you out or specifically refering to you on knowing the difference between use dmotor oil.. and other oil products.. just the 'average' person.. etc.

40 ys ago wasn't that long...good ole' late 60's!

Actually I’ve been thinking this past week on how I’ll prevent water contamination. I think I’ll spread a plastic sheet under the bridge while the treating process is occurring. After the migma dries (it may take a while) I can remove it.


Where can I buy copper naphthenate, or the asphalt based paint? All alternate ideas will be most welcome!

Many years ago we used to treat fence posts with Blue stone

Copper(II) sulfate (CuSO4), spelled "sulphate" in most Commonwealth nations, is a common salt of copper. Copper sulfate exists as a series of compounds that differ in their degree of hydration. The anhydrous form is a pale green or gray-white powder, while the hydrated form is bright blue. The archaic name for copper(II) sulfate is "blue vitriol" or "bluestone"[1]

We can still buy it at the local farm supply stores.

Down here in FL.. the HD stores carry both asphalt paint.. and copper napthenate. I have also seent he asphalt paint at TSC.. and other 'farm' stores. Warning.. CN removes hair and maeks a pretty darn permanent stain on just about anything... even stains skinn for as long as it takes for those cells to sluff off...

I'll go investigate alternatives today, thanks guys!

You might want to put the steel longitudinal members a bit wider apart, to match the track width of heavy machinery like the cement trucks you spoke about. The steel beams will hold a cement truck, but the wood ?????
