I just had a client contact me that needs their gravel parking pad resurfaced. She said that a friend of theirs had recommended a product called asta (?). It's like a concrete/polymer product that creates a hard surface that doesn't allow weeds to grow. Apparently it's being used quite a bit in the Traverse City, MI area. I'm not familiar, and can't come up with anything via Google. Can anyone point me in the right direction?

Really? No one has heard of this? Hmmm...I think her voicemail spelled it AFTA, but it may be ASTA. Shoot.

If it's what I am thinking.....gravel with this polymer pourd over, which will create a hard flat surface with the look of the gravel.

I know someone who had that done for a driveway...........after the first winter......the following winters it would explode in spots and sections.........he had to redo the driveway.

I have a customer that has a crushed 3/8 blue stone driveway that is quite hard and not much gravel movement........this has been down several years now and still looks great.

I think it was a thin black top.......gravel spread over and gone over with a mechanical roller.......does look nice.......best part is that there is no showing of tire track rutting from car and van

I also have seen ads in landscape magazines for a polymer that is mixed into the gravel, wet down and then rolled. It is supposed to make a firm self repairing surface. The supplier was from California I think but darned if I can find it now or remember the name of the product.

I found the stuff I was thinking of. PolyPavement: Natural Soil Pavement - Liquid Soil Solidifier

Thanks- those are what I was coming up with as well. I contacted a landscaper from Traverse City and he didn't know either. Must be a brand new thing

These are some of the better product that will do what you want.
I have installed a few poly products but they didn't hold up well.

Thank you so much Paul. This will come in handy for suggestions for a local golf course.

It turns out that the product in question is AFTON stone- a 22a road gravel product, which, yes, properly compacted, will form a solid surface and generally have little weed growth for a few years but not forever.

We're going to just topdress with p-stone, as that's what they have and like already.
