Looking for opinions on the attempted repair of a two-piece box culvert system using a monolithic slab poured over the entire system.
The culvert system is two culverts wide, 16 long underneath a 4 lane road plus a turn lane. About a month after final completion, longitudinal cracks begam forming in the top pieces of the culverts. The road was shut down immediately for evaluation.
The cause was determined to be incorrect placement of the rebar, and the manufacturer hired a firm to come up with a fix that did not involve removing and replacing the top pieces. The repair was designed by an EI and was approved by a PE who is not a structural engineer.
The design consists of a slab tied into and poured over the entire system. The design references standard plans, but the standard plans are for a monolithic slab poured over one-piece box culverts in order to address differential settling.
The EOR of the original system did not sign off on or thoroughly review the repair plans, saying that it is the responsibility of the engineer that designed it.
We have a set of strain gauges in the slab but were given no guidance on how to interpret them. The original monitoring plan called for them to be placed on the wheel path (4 different locations, two sensors at each.) Instead, they were placed on the white line. I have not been able to get an explanation for this.
We've had one sensor that's been acting odd almost since it came online. It's been steadily increasing and diverging from the other sensors and is now about three times the values of the rest. (Maxed at 220.) It is longitudinal to the white line.
This weekend, the companion sensor (transverse to the white line) took a sudden dip to less than -1000 microstrain. It then spiked up and down going back up to 60 a couple times and then -2500 at its lowest. About the same time, another sensor about 30 feet away started reading a temperature of 200+ degrees.
My instinct is that this repair slab should not have been tied into the original tops and that we now have reflective cracking within the repair slab. I'd appreciate any thoughts anyone has on the issue.
I have a relative that wants to move their savings to a high yield account but she also wants her three kids to all have access. The only way I can think of doing this is to have four owners. My bank, CIT, only allows two. Does anyone know if there are banks that allow for four owners?
