ROAD CONSTRUCTION MATERIALS FROM THE PERSPECTIVE OF ENERGY SAVINGS

The energy consumption of road construction is from the viewpoint of production, processing and transport of materials and mixtures assessed. Total energy and economic demands of a particular technology is the choice of suitable materials and technological processes affected. Tendency of modern society is to find the most acceptable way to reduce the possible negative impact of activities on the environment and humans. In the field of road construction are mainly recycling or reuse of materials, technologies with production and processing at lower temperatures, new materials and additives and not least the modern machine equipment used. From the perspective of sustainable development in road construction it is necessary to use such as environmentally compatible, energy and economical acceptable materials and technologies. It is an effort to reduce the energy intensity of the production and processing of road construction mixtures in order to reduce the possible negative impact, as well as increasing fuel prices. In assessing the energy consumption of road construction is possible to focus on cars, design of road or road construction - from design to placing and compacting of the mixture. The Paper deals with issue of cement concrete pavements and asphalt pavements from the viewpoint of energy consumption in the production and processing of materials and mixtures. Detailed focus is on results of laboratory verification of warm mix asphalt with selected additives.
