What's light green, sprayed on top of asphalt, and lowers the temperature of parking lots by 30 degrees?  Green asphalt!  If you went to school at Robert L. Duffy school in Phoenix, you would have known the answer already. Late last month, the charter school became the testing ground for "green asphalt," a concrete-based reflective covering designed to make asphalt surfaces cooler and more durable.  Phoenix-based Emerald Cities installed the coating at the school to demonstrate the viability of the technology to city leaders and contractors, company CEO Sheri Roese said recently. As part of its efforts to be carbon neutral, the school had its parking lot resurfaced to lower the energy needed for cooling adjacent buildings and make the parking lot more comfortable for students during lunch and recess.
