Pave Your Own Driveway?

Forgive me, but I thought asphalt was all the same. What are the mixes you speak of?

Both concrete and asphalt mixes may have different granular grain size compositions. There are different types of asphalt and cement may be mixed with different ingredients for specific purposes.

The cost of each will vary as to what was used and the temperature the asphalt is mixed at.

A yard = A Yard only in exterior dimensions. The densities can vary considerably.

The cost of the granular mix can vary greatly as to how it is graded, the rock type and availability.

End result cost per yard from one area to the next area has great latitude for difference.

As a note concrete/asphalt deliveries for small jobs have been known to be rejects from jobs requiring testing.

Eddie - I understand the concrete expansion and contraction. Don't you just saw cut it afterwards for that? Then what do you fill the cuts with to keep water from getting underneath?

Expansion joints and cutting the concrete for cracking are two different things. When concrete is exposed to the sun, it expands as it gets hot. When it gets cold, it contract acts. The bigger the slab, the hotter it gets outside, the more it moves. If there was not a space for this movement, the concrete would destroy itself. Most of the time, a 1x4 is plenty of space for this to happen. If you ever drive across a highway you'll notice this by the noise your car makes hitting every expansion joint. Bridges are the same way, but they use something a lot more expensive then wood. Some don't use anything at all in their spacing between each slab.

Cutting the concrete after it's poured helps hide the cracking from using too much water in the mix. It creates a week line in the concrete that allows the concrete to crack in a straight line, so you don't see it. Depending on how big the slab is, and how hot it gets, cutting might allow enough movement in the slab if the cut is big enough to allow for expansion of the concrete when it's hot. I've seen people use 30 pound tar paper for this with good results.

This is not needed when building a house since the inside of the house is always at a constant temperature, so the concrete does not expand or contract.

Where the heck are people getting concrete anywhere close to $100 a yard on a truck? $170 here.

Concrete will not go thru an asphalt paver. It will not flow out to the edges.

I was finally going to surface my gravel drive this year, 45’x70’. After the sixth bid, 3 bit, 3 crete, I gave up and said maybe next year.

Concrete paver is not the same as asphalt paver, two different machines

Concrete supply stores sell felt used as expansion, typical size is 1/2 inch thick

It would be interesting to see what kind of support would be required to feed the slip paver. Pumper, or can the truck drive along side and dump into the hopper?

Then what about your expansion joints or keyway?

OP did not specify, just said working paver for $7,500. You couldn’t buy a working concrete paver for $30,000, let alone under 10 grand. Hence my assumption.

There are so many different concrete pavers I’ve seen. Some that will do two lanes wide, they finish it 100%, almost no hand work. Then there are some low dollar ones. They usually aren’t much more than a vibrating screed that strikes it off and rough finish it, they usually ride on steel forms.

I have never seen a concrete paver that didn’t require a fair amount of hand work behind it

 

[dodge man]

When I’m talking a concrete paver that doesn’t need much if any hand work it’s the kind that does highways and interstate highways. The trucks just dump on the ground in front of it and the machine augers it from there. There is even an arm that follows behind it and swings back and forth to finish it. I’ve seen similar ones used on airport runways and taxi ways.

Even the highway pavers will have 6 to 8 people working behind it.
