When they resurfaced the expressway, they sold that old crushed asphalt to anyone.
Our county got mountains of it, that they started laying on county streets and roads.
They found out soon it would not hold together and developed potholes right away.
Without being laid properly with hot tar, etc., that loose stuff really never compacts properly.
They started mixing it with other, whatever was handy, crushed caliche, screenings, crushed concrete, plain dirt and that worked much better.
I would get someone that knows how to use that to put it down for you, not someone that is clueless, or you too will have a nice area full of potholes.
Our parking lot in front of the barn is the screenings left over from the crushed asphalt, that they were giving away for the hauling, much better for that than the crushed asphalt itself, but weeds and grass will grow in that, unlike on real asphalt.
If you want asphalt, go with the real thing, that will last you much longer, especially if you won’t have the continuous traffic on it city streets and highways have.
Our vet used plain highway asphalt on his vet clinic extension aisle and stalls and seems to like it.
Some of the people that work for them think the regular concrete in the older barns is better.
Will see what others experiences are with that.
