Reinforcing Rigid Pavement

Reinforcing Rigid Pavement

Reinforcing Rigid Pavement


There is a doubt that has been drilling my brain since 2 or 3 weeks ago. Someone ask me if I know something about any special specification or desing criteria for reinforcing concrete pavements within a seismeic zone.
I have never read something about it, in fact I have been searching and asking and nobody around the city could tell me something. There was a guy who told me that he believed that in California used to reinforced the rigid pavements pavements to take the strengths generated by the earthquake but it was all that he known.

I'm not an specialist in this topic but I really can find the sense in adding steel bars to a pavement. But you never known.

Genomty - try to keep your queries to a single thread - many threads do tend to overlap and for many of us, we still have problems trying to judge which best '1' we should put it in - but try to keep it there - best for continuity of discussions, too.  Welcome to ENG-TIPS !!

RE: Reinforcing Rigid Pavement

I have been involved with concrete and asphalt pavement design for 25 years, have worked with the PCA, ACPA and private consultants.  I have been to many research-oriented seminars, know most of the present researchers, and I have never come across any mention of reinforcing concrete pavements for the forces exerted by earthquakes.  First of all, the methodology doesn't exist, even if it did, why would one do this in the first place?

If the reason was to preserve the pavements, I can't imagine the structure that one would come up with that would withstand a Loma Prieta or even smaller magnitude quake.  the cost would be exorbitant and unjustified (its easier to remove and/or repair than build).  

If the reason is to save lives, how many people have been killed by failing pavements in earthquakes???  If you want to save lives, get the multi-taskers (lip-stick wipin', latte-swillin', cell-phone babblin', hairdo checkin', masturbatin' fools)off the road!

A most definite answer.  Too bad it wasn't in the other copy of the same thread that already had some replies.

thanks a lot!

your notes have confirmed my arguments
