Why We Need White Roads

The regular black asphalt roads that we see in our cities are actually a reason that adds to the heat in our cities. The black color tends to absorb more of the sunlight and then releases it after sunset into the atmosphere. This means that temperatures in the heart of the city can be almost five times higher than temperatures fifty miles out in the wilderness, away from the city.

A simple way to counter this measure contributing to global warming is to paint the roads white! Not just any white paint, but a special one developed in LA with the name CoolSeal. This paint ensures that most of the radiation of the sun is reflected back, rather than absorbed by the road. This means that the temperature of the area also drops lower than the areas which have regular black roads.

Yes, painting all the roads in your city with this special paint will be expensive. However, if you count the long term benefits of having a cooler city, and the low electricity bills of the citizens, it may just be an investment worth making. The study of the sustainability of this experiment of painting all the roads in your city white with CoolSeal will make an interesting science project.
