Hmmm… Doesn’t acid rain and other acidic solutions destroy calcium carbonate?

how flexible would this be with contractions and expansions due to heat summer and winter? would lack of durability be supplanted by constant re pavement of roads?

At first blush, a great idea!. Unpaved rural roads are done in a similar fashion using gravel/sand mixture and oil distillates as the bonding agent. Seems to me there is a strong possibility here and potentially represents a good start in saving our environment by "greening" the concrete jungle! Reflecting on Michael's comment, aren't we resurfacing roads annually anyways? The benefits offered reduced carbon emissions lowering associated risks attached to global warming.

Sandstone is in no way malleable. Horrible idea for a road surface. No thought whatsoever put into WHY asphalt is as ubiquitous as it is.

In response to a few comments here. When has your umbrella ever been hit with acid rain? Roads worked pretty well before tarmac was invented so expansion in the summer really wouldn't be an issue as it has no need to. I think the day we need to ask the question of whether stone is more durable than tarmac is the day I need to goto work on a space hopper. Unless you live in a cave, you should know that roads get re-paved all the time, how many roads have you been down that have giant holes in them? I doubt this would need as much upkeep really. The abundance of sandstone along with it's durability and eco-friendliness is clearly a great idea over keep using crappy tarmac. If you have criticisms, then please give reasons why, after knowing a little about both materials. If you keep the surface at the right texture for tyres and treat it in such a way that it doesn't destroy them, there's no reason why you couldn't use sandstone at all. People thought that using limecrete was a stupid idea instead of concrete until it started getting used and now it's not common, but certainly the better of the two, environment wise so in the long haul, don't moan, help with ideas.
