Colorado B.S. Thread

I keep hearing about that. Not even sure where that is.

 

It's 2019. The world will both end soon AND in the meantime things will get worse. Plan for the 1,000 year event.

 

Soo driving over the backfill with a tractor or vehicle is not compacted enough? Asking for a friend!

 

Your big toe puts down more psi than those.

 

What like the overpass on Hwy36?

edit: guess I'm a little behind with that comment

 

I’m going to have to look into this Hwy. 36 thing.

I like like 1/2 mile from this, really snarled my commute until they figured out how to reroute traffic around it, now my exit is just before the hellacious traffic jam starts when I’m trying to get home.

 

Same shit for us down here in the "GAP" project.......

CDOT and the STATE can screw themselves......

 

They missed a chance to title the article "Crack ruins lives"

 

Anyone headed to Rodney Atkins on Friday????????

Platte River Grille!

 

And anyone else headed to the Fillmore the weekend after for Bush/Live?

Wife and I are HUGE concert junkies....so lets meet up!

 

Yep. That would be one solid example of what can happen though that was likely more of moisture issue than contractor negligence. CDOT projects are actually pretty well structured on the QC side. I could go into it a bit more but Ill spare you all, but if you grade a biology exam with an answer key to a chemistry test, things can appear to be correct when they really are not.

 

At Platte River Grille.. well that seems like an odd spot haha. I might have to make it over there

 

Yeah, IIRC we'd had a couple dry years around when they did the construction, then this year has been very wet. And I wouldn't mind hearing more educated speculation, but that's me.

 

Holy jeez does the truck drive better with poly rack bushings. Until mine started clunking I had never noticed how much play they had in them.

 

Dry weather conditions shouldnt play a role but they certainly do make things much more difficult.

That video talked about "fat clays" which are definitely not the preferred material for being underneath a road but even still if they are put in properly can be suitable. What the video didnt talk about is that the greater Denver area has soils, that are not necessarily unique to this area but are definitely exaggerated here more so than just about anywhere else in the country, that experience tremendous volume changes. They swell and contract at pretty surprising levels (swell of 15-20% is not uncommon) and those volume changes are definitely moisture induced. If clay is placed at the proper water content (and protected from moisture loss/gain) than it can last forever. But, if it is not, it can fail very very quickly. This happens because clay isnt porous like a sand so when water is introduced to the material there is no room in between the particles for it to sit so they have to separate to make room for it which causes stability issues. Now if the clay is placed too wet and then is allowed to dry out it will shrink/consolidate which is why you get all these dips in the road that we are blessed with out here. The "proper" water content is the tough part and thats where I was going earlier with the reference to grading the biology exam with an answer key to a chemistry test.

 

This pretty much sums up my dirt knowledge.



Oh and Barley has this

 

Sadly, that pretty much sums up a lot of contractors knowledge as well.
