More stones also make asphalt more slippery in wet conditions don't they?

More stones also make asphalt more slippery in wet conditions don't they?
- alexey-salmin 2y agoI think it's the opposite, this kind of asphalt has very rough surface.
- stavros 2y agoIt has a rough surface in the way that it makes it uncomfortable to walk on, but not in the way that tires will grip to it. Stones are oddly-shaped, but slippery.
- PeterStuer 2y agoBut not the right kind of grit rough. The 'stoney' rough asphalts can be extremely slippery when wet, and even dry they then to extend breaking distance. My guess is they also cause more rolling tire wear and slightly more fuel consuption.
- jmb99 2y agoI’m not sure how you could have worse grip when braking (caused by lower friction) while simultaneously increase tire wear (caused by higher friction), unless I’m misunderstanding something.
- tempestn 2y agoStatic (resisting sliding) vs rolling friction.
- PeterStuer 2y agoTire wear is not just friction. The uneven coarse grit can pound, cut, chip and twist the tire surface all while having less grip/friction.
