This is the type of extreme absurdity that could
only come from the left. The company themselves admits that the product only results in a 10° to 15° cooler surface temperature. And statistics show that the pavement will reach temperatures of 150°. So at
best, you’re only going to reduce pavement temperatures to 135° (still scorching) at a staggering cost of $40,000 per mile.
Dark-colored or black asphalt absorbs between 80% and 95% of the sun's rays, heating up LA's streets up to 150 degrees F. The light-coated streets, on the other hand, reflect much more of the sun's rays and are an average of 10 to 15 degrees F cooler than regular asphalt streets.
While the coatings last for seven years, they are expensive, costing about $40,000 per mile.
Now, pavement that never sees direct sun due to shade provided by trees is considerably cooler than 10° - 15°. Trees provide that shade at a cost less than $40,000 per mile and they last exponentially longer than 7 years. Plus, they have the added ecological benefit of giving off oxygen and providing shelter for wildlife. Finally, when their “life” is over, they can be used for heating or paper.
Los Angeles is spending $40,000 per mile to paint streets white — and it could have a surprising ripple effect on the city
