Overload of the Day

[skyking1]

Here in Washington, they claim it is cheaper. Mill the surface in the morning, send it to the plant and send it back out to lay down in the afternoon. I have read claims that less than 10% of the material is lost and would need to be replaced by new. No idea how accurate that claim is, but it is made regularly.
I can see the reasoning, finding aggregate here in the Puget Sound basin is getting more and more difficult with houses springing up everywhere and nobody wants a gravel pit in "their" back yard.

they grind out between the rumble strips and don't have to go back to restore them.
I did a job with Wildish out of Oregon at Centralia and Chehalis, running tack truck, excavator and loader etc.

They do that here as well to some extent. I don't think that they process it and send it back out that fast, but I'm not sure.

Our state has also experimented with what was called the CRAB method, in which they add cement (dry) to the ground asphalt, then add water and lay it out. They then put a cap lift on it. I don't think it has worked very well as it is really tough to get the mixture and water consistent.

I think apac here grinds and removes and uses milled to repave, then later regrinds the removed asphalt for the next job

IIRC I saw mention years ago of a "Train" consisting of a mill, overhead conveyor to a mixer, hot tank in between, and a paver at the end.

I've seen that done here. Grind it off at the front end of the road train and lay it again out the back.

Most of the big jobs like the interstate were done with belly dumps, then picked up with an elevator like a Roadtec.
It's too much of a PITA to drop and pick the pups.
Now the super solos are the kings of the moderate sized pave jobs. That is mostly all they haul around here.

Great pictures Mike. That overhead one with all the plywood shimming over the island and laid down marker cones, that one shows how much goes into making a move like that happen.

They did that not far from me here, entire width from shoulder to shoulder was milled down whatever thickness they were going, fed through a bunch of machines, and laid back down all in one continuous process. It has been at least 3 or 4 years now and it is as good as any fresh road, no seal has been applied and a few heavy winters, no cracks or disintegration out of the ordinary. It was sure a long train of machinery when they were doing it. I don't remember what heat source they were using to heat it all.

Roadtec has a machine that uses a cold emulsion.

Is that thing made out of plastic? The trailer tires aren’t even squatty

 

[Birken Vogt]

I assume that is his trailer and Herc let him load it on there?

If I was working at that rental yard I would have told him to go get a bigger truck and I did not want to fish my dozer out of a ditch upside down.

 

[Willie B]

Looks like 8 heavy tires on the trailer. From what I see it might be a 15 or 20 ton trailer. If the trailer is overloaded it may not be greatly overloaded.
The truck is another matter.

 

[skyking1]

I got a new spin on it. It's a service truck, right? Air compressor?
Mechanic with a great imagination rigs up air brakes for the trailer.
Nothin but the handbrake baby!

Could be moving it between their job sites and Herc wasn't informed.

 

[boaterri]

300 psi in the tires?

 

[Acoals]

215/75R17.5 trailer tires are rated at about 4500lbs each in dual configuration. 36,000lb max load on the tires in a tandem setup. That dozer isn't that big. The tires are fine, and probably the trailer is as well. The towing vehicle, not so much . . .

Question is--- did he wreck or get pulled over? answer is no. Is what he is doing correct? answer is no.
Is it going to happen today across the U.S.? answer is yes. The reason for these stunts, cheapness.
Which goes back a on going thread about DOT numbers, do I need a bigger trailer and truck?
Answer is yes or hire, simple, but the issue is how can one screw the wording around to mean something
different so it jives with what {They want to read, interpret or hear, that meets their own cheap
behavior along with overloading}.

Or it's gotta move and no one can do it until Tuesday next.
