Remember the thread about different colored roads?
I can't find it... but I remember that someone had seen roads of other colors than black asphalt...
I had meant to do a web page on it, I even ordered a set of digital electronic thermometers to measure the various temps in my garden... but the thermometers had such tiny screws I couldn't get the batteries in... in any case, I just found this article:
New energy uses for asphalt
By ARTHUR MAX, Associated Press Writer Mon Dec 31, 2:14 PM ET SCHARWOUDE, Netherlands - If you've ever blistered your bare feet on a hot road you know that asphalt absorbs the sun's energy. A Dutch company is now siphoning heat from roads and parking lots to heat homes and offices. As climate change rises on the international agenda, the system built by the civil engineering firm, Ooms Avenhorn Holding BV, doesn't look as wacky as it might have 10 years ago when first conceived. Solar energy collected from a 200-yard stretch of road and a small parking lot helps heat a 70-unit four-story apartment building in the northern village of Avenhorn. An industrial park of some 160,000 square feet in the nearby city of Hoorn is kept warm in winter with the help of heat stored during the summer from 36,000 square feet of pavement. The runways of a Dutch air force base in the south supply heat for its hangar. http://news.yahoo.com/s/ap/solar_roa...otw3qN.BVhr7sF

Colorants can be added to asphalt, and that can make the asphalt less hot when the sun shines on it. I think I must have posted it more than 31 pages of posts ago...

I've seen brownish red, burnt red, greenish slate, slate, jet black, black, dark gray, medium gray, light gray, almost sliver,
off white (hot melt topped with crushed rock) and grayish covered with mud, and in Amish country, medium gray with light brown polka dots.

Some parts of town here, they have red brick. Some of those streets that have the red brick also have old trolley tracks.
