Roads appear to shine when wet because of the reflection and refraction of light on the smooth surface of the water. This creates a glossy effect that makes the road appear shiny.
Rough asphalt roads typically have the most friction due to the texture of the surface, which provides better traction for vehicles. Smooth roads, such as concrete or tarmac, may have less friction and can be more slippery, especially when wet.
Icy roads have less friction than dry roads because ice is a smooth and slippery surface, making it difficult for tires to gain traction. The lack of friction between the tires and the icy surface reduces the ability of the vehicle to brake, accelerate, and turn effectively, leading to increased risk of accidents. Dry roads, on the other hand, provide better traction for tires due to the rougher surface, allowing for better control and maneuverability.
High friction is not useful in situations where smooth, effortless movement is desired, such as when driving on icy roads or pushing a heavy object along a smooth surface. Excessive friction can cause wear and tear on surfaces, increase energy consumption, and make tasks more difficult to perform.
The surface of a car can affect its speed primarily in terms of aerodynamics. A smooth and aerodynamic surface reduces air resistance, allowing the car to move more efficiently through the air and achieve higher speeds. Rough or uneven surfaces can create drag, slowing down the car and reducing its speed.
Asphalt. Macadam is another common name for the process. To Macadamize something is to pave it with asphalt.
they were built with smooth rocks on the to top. Then on the side there were paths for people when solider were marching down the road.

Tarmac is not a rock; it is a man-made material used for surfacing roads, driveways, and parking lots. It is a mixture of asphalt and aggregate materials that form a smooth and durable surface. Tarmac is not impermeable and can allow some water to pass through its surface.

roads and paths
Inadequate shocks, and or suspension components that are usually on passenger cars that aren't designed to travel on any surface other than a smooth, paved surface.
The question is "WERE there roads in the Persian empire". The simple answer is no, the Persians only had dirt paths they travelled on but not "roads" by definition being a paved path. The Romans invented roads.
People typically walk on surfaces like sidewalks, roads, grass, dirt paths, or floors indoors. The specific surface depends on the setting and environment in which they are walking.
Roads were not invented. They started as animal trails, then became the worn paths that people walked on. When people developed carts, they began to widen and improve those paths and the result was what we now call roads.
