Water Sucking Concrete?.....Well Almost......

They have been using it in Sweden for a while apparently so it's good for ice. The water is not trapped under the road it soaks away naturally as if there was no road there. Obviously it is for rain and snow not rivers of water. The idea is to prevent floods forming due to water being trapped on the surface.

We actually use something very similar only with asphalt. Makes a great drainage layer.

Our major roads and highways here have that type of asphalt, but to have it in concrete would be nice. The asphalt looks like an open cell foam insulation

Do you know about how thick the layer generally is? We typically place it anywhere from 2.5" - 3" thick. Just curious with your subgrade conditions what you guys use.

On some of the new turnpike construction they have like 6 feet of base, I think there using recycled crushed concrete and the asphalt is like a foot thick. They pave it a few times each time its like 3-4 inches for a regular road its like a foot of base and then like 4 inches of asphalt. But on a driveway to a house the existing earth is compacted and about 3 inches of asphalt. We only have like 4-8 inches of topsoil here and then its solid coral rock if you have to dig a 5 inch hole you better go get the chipping hammer. It sucks the tree roots don't even go down they just stay on the surface
