One of the less pleasant smells associated with the changing seasons comes shortly after winter thaw and spring rains – the extended summer season of highway repair and driveway installation. As you're driving by, trying to ignore the dark fumes, it's hard to think of asphalt as a particularly “green” substance.
However, it is! Environmentally friendly asphalt is much better for the planet than most people assume. It's a fine choice if you're looking for a paving material that does as little damage to the earth as possible.
