Once constructed, asphalt pavements have minimal impact on the environment. Studies show that asphalt pavements and stockpiles of reclaimed asphalt pavement do not leach. 6,7. Environmental applications. Asphalt is used to construct liners and caps for landfills. The impermeable material is an effective barrier to potential leaks.
Asphalt plants are good neighbors, who are active in their community. They offer opportunities for local employment, and often contribute to community events with volunteers and financial donations. Many asphalt plants are family-owned and -operated and have been an important part of their community for decades.

readymade asphalt that is loaded on customer trucks for transportation to the road pavement site. The system is installed in over 30 plants in Sweden and the Nordic region. The purpose of this thesis work is to help them develop a modern HMI (Human Machine Interface) for the SCADA system.
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).
buildings and paved surfaces (asphalt, concrete), roads, parking lots are called impervious surfaces. Increasing urbanization and pressure of population stimulates the growth of impervious surfaces in the cities. Tremendous increase in impervious surfaces has far reaching effects on the landscape and environment of the region.
