Wow 10 Wheels! That doesn't look anything like the chip seal used around here. Those are boulders compared to the shards that are used on the roads as chip seal here in Wisconsin, namely Madison. I'd take a picture of it now but most of it is covered in snow - go figure, but this is Wisconsin.

The tiny pieces are supposedly more of a hazard to puncture bike tires, even the road work signs say for bicyclists to use an alternate route when they put this stuff down initially.
