What does material of road surface mean?

Explanation:
Traction on the road is determined by the surface material and its interaction with tire rubber. The key idea is that friction changes with weather: a dry surface typically provides more grip than a wet one because water reduces the tire’s contact and thus traction. So the material of the road surface is about how much friction or grip it offers under dry versus wet conditions, which directly affects braking and handling. Color, slope, and what the pavement is made of in a chemical sense don’t describe this difference in traction between dry and wet conditions.
