Yes - road surfaces do radiate energy, black ones especially. However, white or light colored road surfaces are also beneficial to us right now because they make up for diminishing albedo caused by the loss of polar ice. Scientists say plenty of heat is being absorbed by earth's atmosphere because it is not being reflected back into space as it used to be up to a short while ago due to the melting ice of the polar caps. One way of making up for this loss is by inventing and adopting white or light colored road surfacing, with black carriageway markings, all over earth, to make up for the loss of extensive white polar ice areas.

Why does a good absorber of radiant energy appear black?
In short, because they "don't reflect'." A matte surface isn't smooth; it has a surface that does not fully reflect light/radiation; the surface looks dull because there's little reflection. A smooth surface will reflect because it's smooth (glass-like) and will reflect or bounce light away from its surface. The surface looks shiny because of the reflection. The color of the surface matters because the darker the color, the more light/radiation is absorbed. Lighter colors reflect light; darker colors absorb light.
What is Best surface to minimize solar heat gain?
The answer lies in the Leslie Cube (look it up in an Internet search). Though the cube demonstrates which surface radiates heat better the principle is the same. A dark colour absorbs solar energy better than a light surface and a matt surface likewise absorbs solar energy better than a gloss surface. Think of it this way ... the amount of solar energy hitting two side by side surfaces is the same for each but the light glossy one will reflect more solar energy and therefore absorb less while the dark matt surface will reflect less solar energy and therefore absorb more. Hence solar heat collectors are black.
Why don't white surfaces absorb as much light as black surfaces?
it's depends on element's of black surface that element absorb the sun light and convert it to thermal energy and in the other side white surface doesn't had a much element like black surface.
What color effect body heat?
Black color absorbs more than it radiates. White color reflects back off most of the absorbed energy into the surrounding. Different colors have varying capacity to retain onto heat energy absorbed from the surrounding.
If a black car and a white car are left in the Sun the black car will tend to be hotter. This is because the black car's surface will more light energy than a white car.?
Black surfaces absorb more energy than any other color
Which surface radiates heat the best?
Dull Black Surfaces

How do you measure the temperature of the sun?
The surface of the sun radiates energy in nearly the same manner as a black body. That is to say, the fraction of light that is emitted at each wavelength is a function of the temperature alone. As a result, we can measure the spectrum of the Sun, and then fit it with a blackbody spectrum to derive the temperature.
Does black hole radiates any type of rays?
Yes, all high energy types. The intensity of each ray depends on the type of black hole. Ultraviolet, X-ray, Gamma

Is the l'oreal Paris feria starry night a blue black?
Yes, it is a bright blue black.
Why a person is cold when he wears black at night?
Because black surface emits more light energy than a white surface at night. Therefore, if we use black shirt, it will take more energy from the body, therefore the person will feel colder
Put the word starry in a sentence?
"Starry" can mean full of stars or star-studded. It can also mean star-like in some way (e.g., shining, sparkling, star-shaped, or lofty). The term "starry-eyed" refers to an overly optimistic, idealistic outlook.The following are sentences containing "starry":It was a quiet, starry night.The cape was black and decorated with a gold starry pattern.She came to Washington as a starry-eyed intern, with grand dreams of making a difference.
Why drain pipes are always painted black?
black is a good absorber and hence a good emmiter of thermal energy. painting the surface black can increase the rate of this transfer of energy, and hence thedrain pipes are painted black:)
Why does black absorb the most energy from the sun?
Firstly, black is not a colour - it is the absence of colour (white isn't a colour either - it is a mixture or combination of all 'colours'). We see colour when its particular wavelength is reflected of the surface of something. The wavelength(s) reflected depends on the composition of the surface. Back to black - so when we see 'black' it is because all wavelengths of light has been absorbed by that surface. Light is energy; all that energy being absorbed = heat.
Why don't white surfaces absorb as much light as black surfaces?
it's depends on element's of black surface that element absorb the sun light and convert it to thermal energy and in the other side white surface doesn't had a much element like black surface.
