Hunks of concrete are falling off the Route 50 bridge, but it isn’t as bad as it sounds, according to the State Highway Administration.
The SHA will be performing maintenance next week, on Oct. 13 and 14, to address what is known as “spalling” of the bridge’s concrete structure, a phenomenon that has caused concern amongst some boaters.
The right-hand eastbound lane will be closed from 7 a.m. to 5 p.m. both days to complete the process.
So in two days they are going to build forms and pour or spray concrete over those areas? Why don't we just save the tax payers $ and patch it with some gause and paper mache? That hole in the deck to the far right looks like a lot more going on than 'spalding'! I appears to have been patched once and has simply fallen out again! This work is no better than putting lipstick on a pig!
Rebar corrosion is what causes spalling. So if they leave that rusty metal in place and slap some concrete over it they will be back fixing it again very soon. The salt air and water will penetrate that exposed area and will more than likely spread the corrosion internally creating expansion and major cracking. It looks from the picture that the top of the column is also damaged.
But if the government says its ok then you have no choice but to believe them..
Not long after this bridge was built(completed ahead of schedule) cracks were found in the super structure. Immediate weight limits were imposed on trucks that needed to cross this bridge. The old bridge is in better shape than the new one.
When will you guys get it ? There isn't any money left for these types of repairs. We have to pay all the illegals , the welfare , the food stamps , the housing , the medical bills , the school lunches , the clothing allowance , the condoms , the abortions , the cell phones , the drug rehabs and many many more.
3:07 You are so very much wrong. Corrosion of reinforcing steel and other embedded metals such as rebar happens to be the leading cause of deterioration in concrete. When steel corrodes, the resulting rust occupies a greater volume than the steel. This expan- sion creates tensile stresses in the concrete, which can eventually cause cracking, delamination, and spalling.
My sidewalk is spelling and doesn't have rebar. It uses some type of newerish concrete which I can't recall the name of. So spalling can be caused by things other then rebar, like heat or even a MUX with too much water when poured.
It must be blamed on global warming so we can get energy credit money to replace the bridge! Now, everybody needs to pony up another thousand this year on the electric bills to pay for it!
No alarm here only big chunks of concrete falling off.

ReplyDeletePutting a band-aid on something that needs major surgery?????? Yea thats smart!!!!
ReplyDeleteBlame it on Bush, right Obama?
ReplyDeletePlease, until a flood.

I pray to God there are smarter people than you working on this problem
DeleteLol rebar corrosion doesn't cause spalling. Do some research.

Extreme heat causes spalling.

DeleteMaybe it is time for them to think about building a new bridge. Something that they will not have to open and shut and tie up traffic.
ReplyDeleteExposed rebar may not pose a threat but falling chunks of concrete could.
ReplyDeleteDeclare the bridge unsafe and watch how fast they either repair or replace it. They need that tax money that OC generates each season.

ReplyDelete5:15 that is the truth.
ReplyDeleteCut oil subsidies and corporate welfare and there would be money to fix infracture.
ReplyDeleteA pavement that can spell and it contains newerish concrete - WOW!
