Best Sealer to use on Recycled Asphalt

Hi Guys,

So after a painfull week and a half we've finally finished our new driveway. Did a recycled asphalt and it turned out pretty good but I feel like its going to deteriorate quickly, especially in the winter when I take a snow shovel to it.

We sprayed it with Calcium Chloride as the paving company suggested but that didnt seem to do anything so I'm thinking about putting some sort of sealer on it.

The problem is, there's so many different types and I have no idea which would work best on recycled asphalt.

Theres, asphalt emulsion (which everyone seems to say is junk), water base coal tar, rubberized coal tar, acrylic, epoxy and I'm sure several others.

Any advice would be really appreciated.

Can you contact whoever made the recycled asphalt? I would think they would know best.
I don't understand the use of calcium chloride - that's basically strong salt water

They're who recommended the calcium chloride, if you google it it seems its quicte highly regarded for road stabilization but it didn't seem to do much.

Calcium chloride will attract water so it's often used for dust control. Can't come up with a reason to put it on asphalt.

It retains moisture so prevent it from drying out, it also helps bind and stabilize the agragate as well as improves compacting. It is widely used in road reclamation.

I suspect the calcium chloride is only useful in the curing process of the asphalt. It's pretty corrosive! I have in in the tubes of the back tires on my tractor but if the tube leaks it will rust the rim if the tube busts, it will kill whatever vegetation it gets on.

That probably leaves you using one of the asphalt sealers but they usually recommend that the asphalt cures for one year before application. I don't know how much [if any] that changes with recycled asphalt.
