I worked for Department of transportation testing materials that go into road construction, there is asphalt that is clear its just more expensive to make, I know on Cali they were testing a grey asphalt to lower Temperatues in city roads. It’s really not cost effective to change the binder color when roads are typically milled and filled every couple of years. The clear asphalt was to maintain a dirt road look for a rural town in Canada I believe.
