Pave Your Own Driveway?

[PILOON]

As far as you want. Once.

LOL, good response.

I also worked on a job at an airport apron, I was doing inspection and taking concrete beams(test specimens). The pavement was thick, like 24” thick. They didn’t haul in dump trucks but used what they called buggies. Almost like a concrete truck with the drum cut in half, but smaller. They didn’t spin, just brought the concrete and dumped. The plant was really close, maybe a 1/4 mile away.

When they did the interstate here, almost all of the trucks were dump trucks or those half-round dumps. The plant was about 5 miles away.

I watched them rebuild a airport runway here a few years back. The concrete was 15 inches thick with standing rebar. They used a combination of dumb trucks and belly dumps. They just dumped in front of the slip form machine. The aggregate pile feeding the concrete plant was huge. They brought in a mobile concrete plant just for the runway.

How far can you haul concrete in a dump truck?

You mean 'How long"

The airport was about 6 miles, the border crossing was 18 miles, probably 25-35 minutes with traffic and speed zones etc., I really don't know how far or how long concrete can be hauled in a dump truck, it would depend on the air temp, humidity and mix design.

I wonder how many bumps in the road it would take for most of the aggregate settle to the bottom.

It'll all get mixed up again when they dump it and the auger starts chewing on it. It must be working... all our concrete highways are in great shape!

That’s the problem with hauling concrete in trucks that don’t spin, it can segregate.

I didn't see it. I am pretty sure it was a zero slump mix . It self leveled after the drive, but there was no migration of water to the top even after the drive in a hard spring Mack.
.I mixed some concrete at home dumped it into my tractor bucket and took it about 1200 feet to anchor in a corner post and it had all separated out so I know what you mean. Dump truck hauling has it's obvious limits.
