Cool off asphalt

Will painting asphalt lower it's temperature? If you take asphalt from
black to a light color will the surface heat lessen?

Cool off asphalt

Yes. What you are referring to here is the material's Albedo or it's solar reflection index (SRI). In general terms, the lighter a surface color, the more solar radiation is reflected rather than absorbed.
