Asphalt is Environmentally Friendly

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.

Effects of Soil Compaction

Some bacteria such as rhizobia provide nitrogen to plants. Some fungi live in symbiosis with plant roots, facilitating the uptake of immobile nutrients such as phosphorus and potassium. Only few bacteria and fungi have negative effects (e.g., plant diseases). Bacteria and fungi are at the bottom of the soil food web (Figure 12).
