I had a driveway poured a few weeks ago.
I inspected the driveway 2-weeks after the completion. (I live out of town)
The 14' wide driveway had a crack all the way across the width and down both sides of the slab (4" thick).
This line is directly over a PVC pipe that was placed under the driveway in order to run cables in the future. (General Contractor suggested it for this purpose)
Everything I have read online says that the only reason this would crack all the way across was because the ground was not prepped for the pvc pipe and the pipe was just laid on the ground and the concrete was poured over it.
Does anyone have expertise on their opinion of what could have caused this crack?

The contractor has offered the following repair
1) Grind a "V" trench at the crack approximately 3/4 of an inch wide.
2) Blow out concrete powder and debris.
3) Inject two part epoxy made by Simpson Strong Ties into the v trench/crack. Same material that is used to anchor seismic ties or anchor bolts.
4) Fill the top layer; approximately 1/2 inch with 8000 psi concrete mix. Called Sheplers Patch Plus.
5) Fill the last layer with Eucoreco surface patch.
6) Blend in the panel to color.

I am being told by non-experts in construction, that they believe this is just a band-aid and it will fail in a few years.

Does anyone have any experience with driveway construction, concrete, the products that are proposed to repair the crack ??

any input would greatly be appreciated.

Without looking at the entire driveway I can only suggest that there are not enough/any expansion joints, from the picture it appears the pvc is at the bottom of the slab so at least 4" deep. This is enough coverage. The epoxy is a fix as long as the stress at that point has been removed. There is a possibility that you could saw cut out a section of the drive way and rep our ?
Can you let me know how far apart the expansion joints are from each other ?
It sounds like your contractor is going to fix either way.

every 8-10', i did not measure it, but that is my guess by eye balling it.

You can use the epoxy as your contractor suggested or cut out the section over the pipe and re pour, that would require rebar to be installed (drilled) into the adjacent sections and new concrete poured over that.
I would recommend to have the stress relieved to help with this issue in the future.
