liquid slag. Basic oxygen furnace slag has increased skid resistance and high level of strength described by the impact- and crushing value compared to natural rocks and thus makes it an ideal aggregate for road constructions and surface layers for high skid resistance. 2. Oct 27 2015 · The basic skid resistance representation is the graph giving the variation of friction coefficient with speed (figure 15). It can be seen that wet skid resistance decreases with speed and the decrease rate depends strongly on the road surface macrotexture.
