Some properties of crushed stone for road surfaces

For this surface texture on the macroscale, beside the particle size of the aggregate also the resistance to crushing and abrasion is rather important. The macroroughness is likely to decrease rapidly in case of insufficient resistance to crushing which will cause destruction of stones at the surface.
