Answer 1

Answer:

As others have noted, the majority of roads are paved with asphalt and asphalt roads tend to be black or dark gray in color largely because the asphalt cement (bitumen) is a petroleum product that is dark brown to black in hue.

Explanation:

Why are Roads Black

why roads are black in colour, why aren't roads white, what is the black stuff on the road called, asphalt road, black asphalt

Black Asphalt

There are reasons that I identified and that I want to share

asphalt concrete is available at a low price. The cost that occurs to made of asphalt concrete is also low.

During the summer and high temperatures, the black color does not reflect the solar waves that will help us to see the roads clearly.

Asphalt concrete absorbs heat but that doesn’t affect to visibility in extremely hot conditions.

In night times bright colors can be easily seen on black roads. whereas bright colors on white roads cannot easily be identified. We can easily say that white lines can be easily identified on black roads whereas white line road markings cannot be identified easily on the white roads.

In addition, any irregularity on the road, with the exception of the black color, can be simply detected.

Asphalt concrete has a higher adhesion with rubber than concrete roads.
