Wasn't sure where to post this, so here goes. We probably all notice the massive differences in road surface quality when we ride our bikes. I'm specifically not talking about potholes and other damaged surfaces, though. Is there anyone here who knows why a particular surface type is chosen for a given stretch of road? Obviously motorways get a slightly different treatment but I've noticed on the same stretch of road you'll get the small stone (chips) dressed surfaces (me no likey), some smooth black tarmac, then the more grey harder stuff. When a new road is put down around here, it's pot luck what type of surface they will choose, often it's the stone chips but occasionally on a piece of road a beautiful surface is laid and I can't see why (but glad it is) that would be. I don't know the actual names for these road surfaces and wouldn't be surprised if someone here does! Anyone cast their expertise here? I wish all roads were the smooth type!
