If you use recycled asphalt that has been run through the crusher to come out as 3/4 inch size, you lay it down and spread it level, when it gets hot out, this stuff will harden up nicely, preventing moisture from the ground.
Most permanent asphalt plants have a pile of broken asphalt that they crush and add to the new asphalt, but they sell it as well. Very inexpensive. Because it's asphalt, no dust, too.
If you decide to concrete later, it's a perfect base for concrete.
Great substitute for gravel on a driveway..."sets up" in the heat and no dust.
