The aggregate used in the asphalt polished under traffic conditions. This polished aggregate is what sparkles under certain lighting.

What are the benefits of white pavement?

Reflective pavements decrease the amount of heat that is absorbed at the Earth’s surface and thus lower surface temperature. This decrease in surface temperature reduces the transfer of heat into the atmosphere, which offsets a portion of the warming from greenhouse gases and thereby delays climate change.

Why can roads be white?

LA is attempting to fight climate change by painting streets grayish-white with CoolSeal. CoolSeal is made by a company called GuardTop, and it helps to reflect solar rays off asphalt so that less heat is actually absorbed.

Why is asphalt white?

Heat Reflectivity: White asphalt roads have a high reflectivity factor, meaning they reflect a significant amount of sunlight instead of absorbing it. This helps in reducing the urban heat island effect and keeps the surrounding areas cooler.

Does black asphalt turn white?

Black bituminous pavement appears to turn grey and lighter over time. What is actually happening is the black asphalt cement that completely covers the aggregate oxidizes at the surface due to UV exposure and other weathering elements.

Why is asphalt black and not white?

Asphalt is derived from bitumen – a side-product of petroleum distillation. Bitumen is black. So there would be significant cost added to make roads in colors, as black can’t be easily tinted – so you would have to find a white(r) material that functions as well and as cheaply as bitumen.

Why is new asphalt so dark?

Fresh asphalt pavement is black because all the particles in it are covered with a layer of fresh tar. With time, the tar gets covered with road dust and grit, and the topmost surface of the pavement gets the tar worn off to expose the aggregate. both these effects lighten the surface color.
