Asphalt is Environmentally Friendly - Asphalt Pavement ...

Asphalt pavements do not leach; therefore, once constructed, asphalt pavements have minimal impact on the environment. Studies show that asphalt pavements and stockpiles of reclaimed asphalt pavement do not leach. Asphalt is used to construct liners and caps for landfills. The impermeable material is an effective barrier to potential leaks.
